Switch Mode Power Supply S8VM 3

Specifications

■Ratings/Characteristics

Note: 1. Do not use the Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power

Supply may result in ignition or burning.

2. Refer to the Engineering Data section on page 7 to 8 for details.

3. If the V. ADJ adjuster is turned, the voltage will increase by more than +20% of the voltage adjustment range.

When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.

4. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

5. Conducted emissions: The noise value is affected by factors such as the wiring method. The product conforms to Class B when the aluminum plate is laid under the

product. For 15-W models, insert a clamp filter (ZCAT2436-1330 by TDK: 50 Ω min. [50 to 500 MHz], or the equivalent) in the output wire to reduce noise.

6. Radiated emissions: The noise value is affected by factors such as the wiring method. The product conforms to Class B when the aluminum plate is laid under the product.

For 150-W models, insert a clamp filter (ZCAT2017-0930 by TDK: 35 Ω min. [50 to 500 MHz], or the equivalent) in the input wire to reduce noise.

7. UL1604 (Class I/Division 2) and CSA C22.2 No. 213 (Class I/Division 2) approval pending for 150-W models. However, S8VM-15024@@ models are designed for com-

pliance with an output rated current of 6.3 A max.

Engineering Data

■Derating Curve

Note: 1. Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the

area shown by shading A in the above graphs).

2. If there is a derating problem, use forced air-cooling.

3. When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models

cannot be used side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference

value, allow at least 50 mm spacing on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of

80% or less.

4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above

derating curves.

■Mounting

Note: 1. Improper mounting will interfere with heat dissipation and

may occasionally result in deterioration or damage of inter-

nal parts.

Use the product within the derating curve for the mounting

direction that is used.

2. Use the metal plate as the mounting panel (*1).

3. Install the Power Supply so that the air flow circulates

around the Power Supply, as the Power Supply is designed

to radiate heat by means of natural air flow.

4. Mounting screw tightening torque

(recommended value: 0.49 N·m)

■Remote Sensing Function

(S8VM-100@@@@/150@@@@ only)

This function compensates a voltage drop on the load lines.

To use this function, connect after removing the two short bars of the

remote sensing terminal.

Note: 1. Use a 2-conductor shielded cable as a connection wire (*1).

2. Use as thick a wire as possible since high voltage drops on

the load lines (*2) may activate the overvoltage protection

function.

3. Use when the voltage drop is 0.3 V or lower.

4. When the +S and −S terminals are opened with the short

bar removed, the overvoltage protection function is activat-

ed and the output voltage will be cut off.

5. If the load line is too long, use an electrolytic capacitor in the

following 3 locations:

1) Across the load terminals

2) Between the +S terminal and + terminal

3) Between the −S terminal and − terminal

Select the capacity of the connected capacitor from be-

tween several tens to several hundreds of µF as a guide,

and then determine the capacity when actually connecting

the capacitor between terminals as shown below.

Switch Mode Power Supply S8VM 9

■Overload Protection

The Power Supply is provided with an overload protection function

that protects the Power Supply from possible damage by short-circuit

and overcurrent.

When the output current rises above 105% min. of the rated current,

the protection function is triggered, automatically decreasing the out-

put voltage. When the output current falls within the rated range, the

overload protection function is automatically cleared.

The values shown in the above diagrams are for reference only.

Note: 1. Internal parts may occasionally deteriorate or be damaged

if a short-circuited or other overcurrent state continues dur-

ing operation.

Eliminate the overcurrent state as soon as possible.

2. Internal parts may possibly be deteriorated or damaged if the

Power Supply is used for applications with frequent inrush cur-

rent or overloading at the load end. Do not use the Power Supply

for such applications.

■Overvoltage Protection

Consider the possibility of an overvoltage and design the system so

that the load will not be subjected to an excessive voltage even if the

feedback circuit in the Power Supply fails. When an excessive

voltage that is approximately 140% of the rated voltage or more is

output, the output voltage is shut OFF, preventing damage to the load

due to overvoltage. Reset the input power by turning it OFF for at

least three minutes and then turning it back ON again.

The values shown in the above diagram are for reference only.

*1 S8VM-@@@24A@/P@

*2 Except for S8VM-@@@24A@/P@

Note: 1. Do not turn ON the input power again until the cause of the

overvoltage has been removed.

2. The overvoltage protection function may be activated when

the output voltage adjuster (V.ADJ) is set to a value that ex-

ceeds +20% of the rated output voltage.

■Undervoltage Alarm Function (Indication and Output)

(Only S8VM-@@@24A@/P@)

If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an

output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@).

Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@) Leakage current when OFF: 0.1 mA or less

Sourcing type: (PNP) (S8VM-@@@24P@)

30 VDC max., 50 mA max.Residual voltage when ON: 2 V or less

•Undervoltage Alarm Function 1 (DC LOW1)

Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V

lower than the voltage output at an output voltage of 24.0 V).

During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is

used as a latch holding function.)

•Undervoltage Alarm Function 2 (DC LOW2)

Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V).

During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights.

Note: 1. This function monitors the voltage at the Power Supply output terminals.

To check actual voltage, measure voltage on the load side.

2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1).

3. Once undervoltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status of the LED (6: Yellow)

light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON again.

4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output

hold status for detection may be reset.

Probable cause of error Troubleshooting methods

--- --- 1

A momentary power failure has occurred in the

input.

Check that the output voltage is normal and no problems have occurred in other devices. No problems

will be caused by continuing to use the Power Supply as is. To clear DC LOW1 (LED display and tran-

sistor output status), turn OFF the input power, and wait at least 60 s before turning ON the input Power

Supply again.

A momentary overload has occurred. The load current has probably exceeded the rated current. We suggest reducing the connected load

or replace the Power Supply with one that has a higher capacity.

A momentary output voltage drop has occurred

at startup due to the capacity of the capacitive

factors on the load side or when the load is acti-

vated.

A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power

Supply with one that has a higher capacity.

The output voltage has returned to normal volt-

age following a rapid drop caused by using the

output voltage adjuster (V.ADJ).

Turn OFF the input power, and wait at least 60 s before turning ON the input power again to clear the

indicator status.

Deterioration due to age (when the Power Sup-

ply has been used for several years)

The internal parts of the Power Supply may have deteriorated due to age. We suggest replacing the

Power Supply. Also replace other Power Supplies that were purchased at the same time.

Overload (immediately following first use of the

Power Supply or when increasing the load)

The load current has probably exceeded the rated current. Check the actual load current and Power

Supply capacity. Continued use in overload status may damage the Power Supply.

The output voltage dropped to -10% or lower of

the rated voltage resulting from using the output

voltage adjuster (V.ADJ)

Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ).

A sudden overload occurred and the Power

Supply remains in overload status.

An error has probably occurred in the load device. Turn OFF the input power, and check whether any

errors have occurred in the load device. Continued use in overload status may damage the Power Sup-

ply.

The output voltage remains low after a rapid

voltage drop caused by using the output voltage

adjuster (V.ADJ).

Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ). To clear DC

LOW1 (LED display and transistor output status), turn OFF the input power, and wait at least 60 s be-

fore turning ON the input power again.

The overload status continues to fluctuate fol-

lowing a sudden overload.

An error has probably occurred in the load device. Turn OFF the input power, and check whether any

errors have occurred in the load device. Continued use in overload status may damage the Power Sup-

ply. 5

Deterioration due to age (after using the Power

Supply for several years)

The internal parts of the Power Supply may have deteriorated due to age. Replace the Power Supply.

Also replace other Power Supplies that were purchased at the same time.

Overload (immediately following first use of the

Power Supply or when increasing the load)

The load current has probably exceeded the rated current. Check the actual load current and Power

Supply capacity. Continued use in overload status may damage the Power Supply.

Power Supply interrupted or damaged. Check whether the input power is being applied correctly. If there is no output even though the input

power is applied correctly, the internal circuit is probably damaged.

Overvoltage protection operation Turn OFF the input power, and wait at least 3 min before turning ON the input power again. If the same

status recurs, the internal circuit is probably damaged.

The short bar has fallen off, or the +S and -S ter-

minals are open.

Check whether the +S and -S terminals are open. If so, the overvoltage protection function is activated.

Therefore, turn OFF the input power and wait at least three minutes before turning it ON again. (S8VM-

10024A@/P@ and S8VM-15024A@/P@ models only)

Output short-circuit Remove the cause of the output short-circuit.

Intermittent operation due to overload (S8VM-

01524A@/03024A@ only)

The load current has probably exceeded the rated current. Check the actual load current and Power

Supply capacity. Continued use in overload status may damage the Power Supply.

The Power Supply fails to start repeatedly due

to the capacity of the capacitive factors on the

load side.

A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power

Supply with one that has a higher capacity.

The input turns ON and OFF repeatedly. Check whether the Power Supply’s input voltage is being applied correctly.

The status repeatedly switches between normal

operation and output short-circuit.

An error has probably occurred in the load device. Turn OFF the input power, and check whether any

errors have occurred in the load device.

Safety Precautions

■Precautions for Safe Use

Mounting

Take adequate measures to ensure proper heat dissipation to

increase the long-term reliability of the Product.

Be sure to allow convection in the atmosphere around devices when

mounting. Do not exceed the range of the derating curve.

Use the metal plate as the mounting panel.

When cutting out holes for mounting, make sure that cuttings do not

enter the interior of the Product.

Improper mounting will interfere with heat dissipation and may

occasionally result in deterioration or damage of internal parts.

Use the Product within the derating curve for the mounting direction

that is used.

When mounting two or more Power Supplies side-by-side, allow at

least 20 mm spacing between them, as shown in the above

illustrations.

The internal parts may possibly be damaged if mounting screws are

over inserted. Refer to Dimensions on page 12 for maximum depth of

insertion inside the Power Supply.

Several Power Supplies cannot be connected. (Only S8VM-

100@@@@/150@@@@) Keep the Power Supply as far away from

heating elements as possible when installing. As a reference value,

allow at least 50 mm spacing on the right and left sides. If only 20

mm spacing is allowed, use the Power Supply at a load ratio of 80%

or less.

Wiring

Connect the ground completely. A protective earthing connection

stipulated in safety standards is used. Electric shock or malfunction

may occur if the ground is not connected completely.

Minor fire may possibly occur. Ensure that input and output terminals

are wired correctly.

Do not apply more than 100 N force to the terminal block when

tightening it.

Be sure to remove the sheet covering the Product for machining

before power-ON so that it does not interfere with heat dissipation.

Use the following material for the wires to be connected to the S8VM

to prevent smoking or ignition caused by abnormal loads.

Over heating or fire can result from inadequately sized wiring

materials when problems occur at the load. As a general rule, always

select wire sizes suitable for at least 1.6 times the rated current.

Recommended Wire Types

Selection of Wires

Select wires for the Power Supply carefully. Refer to this table when

selecting the wires.

Recommended Maximum Current

Minor electric shock, fire, or Product failure may

occasionally occur. Do not disassemble, modify, or repair

the Product or touch the interior of the Product.

Minor burns may occasionally occur. Do not touch the

Product while power is being supplied or immediately

after power is turned OFF.

Fire may occasionally occur. Tighten terminal screws to

the specified torque of 1.6 N·m.

Minor injury due to electric shock may occasionally occur.

Do not touch the terminals while power is being supplied.

Minor electric shock, fire, or Product failure may

occasionally occur. Do not allow any pieces of metal or

conductors or any clippings or cuttings resulting from

installation work to enter the Product.

The table is applicable to wires with 1 to 4 conductors. Keep the cur-

rent value to within 80% of the values shown in this table when using

wires having 5 or more conductors.

XH Connector Preparation

The following Products are provided with the S8VM-05024A@/P@,

S8VM-10024A@/P@ and S8VM-15024A@/P@ for the undervoltage

alarm transistor output wiring.

Be sure to prepare the connector according to the following instruc-

tions to ensure correct wiring. For details, refer to the JST catalog.

•Use a wire size of AWG22 to AWG28.

•The guideline for the length of sheath to be stripped from the wire is

2.1 to 2.6 mm.

•Use either a YC or YRS Crimping Tool (manufactured by JST) to

crimp the terminal and wire.

•Be sure to insert the crimped terminal wires into the housing fully

until a click is heard. Also, make sure that the wires attached to the

housing are securely locked in place.

Installation Environment

Do not use the Power Supply in locations subject to shocks or

vibrations. In particular, install the Power Supply as far away as

possible from contactors or other devices that are a vibration source.

Install the Power Supply well away from any sources of strong, high-

frequency noise and surge.

Operating Life

The life of a Power Supply is determined by the life of the electrolytic

capacitors used inside. Here, Arrhenius Law applies, i.e., the life will

be halved for each rise of 10°C or the life will be doubled for each

drop of 10°C. The life of the Power Supply can thus be increased by

reducing its internal temperature.

Ambient Operating and Storage

Environments

Store the Power Supply at a temperature of −25 to 65°C and a

humidity of 25% to 90%.

The Internal parts may occasionally be deteriorated or damaged.

Do not use the Power Supply outside the derating range (i.e., under

conditions indicated by the shaded area ( ) in the derating

curve diagrams on page 7.)

Use the Power Supply at a humidity of 30% to 85%.

Do not use the Power Supply in locations subject to direct sunlight.

Do not use the Power Supply in locations where liquids, foreign

matter, or corrosive gases may enter the interior of the product.

Overcurrent Protection

Internal parts may occasionally deteriorate or be damaged if a short-

circuited or other overcurrent state continues during operation.

Eliminate the overcurrent state as soon as possible.

Internal parts may possibly be deteriorated or damaged if the Power

Supply is used for applications with frequent inrush current or

overloading at the load end. Do not use the Power Supply for such

applications.

Charging the Battery

If a battery is to be connected as the load, install an overcurrent

limiting circuit and an overvoltage protection circuit.

Dielectric Strength Test

If a high voltage is applied between an input and the case (PE/FG), it

will pass though the LC of the built-in noise filter and energy will be

stored. If the high voltages used for dielectric strength testing are

turned ON and OFF with a switch, timer, or similar device, impulse

voltage will be generated when the voltage is turned OFF and

internal parts may possibly be damaged. To prevent the generation

of impulse voltages, reduce the applied voltage slowly with a variable

resistor on the test device or turn the voltage ON and OFF at the

zero-cross point.

When performing the test, be sure to short-circuit all the output

terminals to protect them from damage.

Insulation Test

When performing the test, be sure to short-circuit all the output

terminals to protect them from damage.

Inrush Current

When two or more Power Supplies are connected to the same input,

inrush current is added to the total current. Select fuses and circuit

breakers giving sufficient consideration to the fusing or operating

characteristics so that fuses will not burn and breakers will not break

due to inrush current.

Output Voltage Adjuster (V.ADJ)

Default Setting: Set at the rated voltage

Adjustable Range: Adjustable with output voltage adjuster (V.ADJ) on

the front panel of the Product from −20% to 20% of the rated output

voltage (−10% to 20% of the rated voltage for S8VM-@@@24A@/P@)

Turning clockwise increases the output voltage and turning

counterclockwise decreases the output voltage.

The output voltage adjuster (V.ADJ) may possibly be damaged if it is

turned with unnecessary force. Do not turn the adjuster with

excessive force.

After completing output voltage adjustment, be sure that the output

capacity or output current does not exceed the rated output capacity

or rated output current.

The output voltage may increase beyond the allowable voltage range

(up to +20% of the rated voltage) depending on the operation of the

output voltage adjuster (V.ADJ). When adjusting the output voltage,

check the output voltage of the Power Supply and be sure that the

load is not damaged.

When increasing the output voltage to more than +20% of the rated

value using the output voltage adjuster (V. ADJ), the overvoltage

protection function may operate.

(S8VM-@@@24A@/P@ Only)

Turn the output voltage adjuster (V.ADJ) slowly. When decreasing the

output voltage quickly, or when adjusting the output voltage to less

than −10% of the rated value, the undervoltage alarm function may

operate.

DIN Rail Mounting

When mounting to a DIN Rail, lower the

S8VM onto the Rail until the Rail stopper

clicks into place, hook section A over the

edge of the Rail and push in the direction of

To remove the S8VM from the DIN

Rail, insert a screwdriver into section

C and pull the S8VM away from the

Rail.

Series Operation

Two Power Supplies can be connected in series.

The (±) voltage output can be accomplished with two Power Sup-

plies.

Series Operation

Note: 1. If the load is short-circuited, a reverse voltage may be ap-

plied inside the Power Supply unit, and this may possibly

cause the deterioration or damage of the Power Supply unit.

Connect the diode as shown in the figure. Use the following

guidelines to select the diode to be connected.

2. Though Products having different specifications can be

connected in series, the current flowing through the load

must not exceed the smaller rated output current.

Parallel Operation

The product is not designed for parallel operation.

In Case There Is No Output Voltage

The possible cause for no output voltage may be that the overcurrent

protection or overvoltage protection has operated. The internal pro-

tection circuit may operate if a large amount of surge voltage such as

a lightening surge occurs while turning ON the input power.

If there is no output voltage even after checking the following points

please contact us.

Check the Overload Protected Status

Check whether the load is in overload status or is short-circuited.

Remove wires load when checking.

Attempt to Clear the Overvoltage or Internal Protection

Function

Turn the input power OFF once, and leave it OFF for at least 3 min-

utes. Then turn it ON again to see if this clears the condition.

Check whether the +S terminal or −S terminal is opened with the

short bar removed. (S8VM-100@@@@/S8VM-150@@@@ only)

Check if the output voltage has been adjusted to more than +20% of

the rated value by output voltage adjuster (V. ADJ).

Buzzing Noise when the Input Is

Turned ON

(50/100/150W)

A harmonic current suppression circuit is built into the input power.

This circuit can create noise when the input is turned ON, but it will

last only until internal operation stabilizes and does not indicate any

problem in the Product.
