Mounting
15 and 30 W
Note: 1. 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. Do not use the Power
Supply mounted in any way not shown above.
2. Use a mounting bracket (S82Y-VS30P, sold separately)
when the Product is mounted horizontally.
3. Heat dissipation will be adversely affected. When the
Product is mounted facing horizontally, always place the
side with the label facing horizontally.
4. Use PFP-M End Plates on the top and bottom of the Power
Supply when mounting horizontally on a DIN rail.
60, 90, 120, 180, 240, and 480 W
Note: Improper mounting will interfere with heat dissipation and may
occasionally result in deterioration or damage of internal parts.
It may also result in failure of the maintenance forecast monitor
function. Use the standard mounting method only.
Overload Protection
The load and the power supply are automatically protected from
overcurrent damage by this function.
Overload protection is activated if the output current rises above
105% of the rated current.
When the output current returns within the rated range overload
protection is automatically cleared.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation.
2. Internal parts may possibly deteriorate or be 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.
Peak Output Current (S8VS-48024@ only)
The peak current must satisfy the following conditions.
Input voltage range: 200 to 240 VAC
Peak current value: 30 A max.
Peak current pulse width: 2 s max.
Cycle: 60 s min.
Note: 1. Two seconds after the peak current is reached, the peak
current limiting function operates to stop the peak current
flow.
2. It takes 60 seconds for the peak current to be able to flow
again.
3. The peak current limiting function prevents the peak current
from flowing at 100 to 120 VAC.

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. If an excessive voltage that
is approximately 130% of the rated voltage (but approximately 110%
of the rated voltage for the S8VS-09024@@@S) or more is output, the
output voltage is shut OFF. Reset the input power by turning it OFF
for at least three minutes and then turning it back ON again.
Note: Do not turn ON the power again until the cause of the
overvoltage has been removed.
Inrush Current, Startup Time, Output Hold Time
Undervoltage Alarm Indication
LED (DC LOW: red) lights to warn of output voltage drop.
Detection voltage is set to approx. 80% (75 to 90%) of the rated output
voltage.
Note: This function monitors the voltage at the power supply output
terminals. To check actual voltage, measure voltage on the
load side.
Undervoltage Alarm Function (Indication and
Output) (S8VS-@@@24A@@/S8VS-@@@24B@@/
S8VS-@@@24BE@ Only)
When output voltage drop is detected, an alarm (a01) and lowest
output voltage value are indicated alternately. The preset value of
detection voltage can be changed in the setting mode.
(From 18.5 to 27.5 V in 0.1-V steps. The value is fixed at 20.0 V for
the S8VS-06024A/S8VS-06024B.)
Further, an output (undervoltage output terminal (DC LOW)) to an
external device is given from the transistor to notify of the error
(excluding S8VS-06024A/S8VS-06024B/S8VS-@@@24BE@).
(Output voltage drop = OFF, i.e., no continuity at the undervoltage
output terminal (DC LOW).)
Example: Outputting an Alarm When the Voltage Output by the
S8VS-09024A@@ Drops to the Set Value (19.0 V) or Lower
:
Note: 1. Operation begins after about three seconds since the AC
power is supplied.
2. The alarm is not indicated in the setting mode.
3. Press the (Mode Key (8)) after the output voltage is
restored, to reset alarm indication.
4. The undervoltage alarm function may also operate when an
interruption in AC input is not restored within 20 ms.
5. The undervoltage alarm function monitors the output
terminal voltage of the Power Supply. To check the voltage
accurately, measure the voltage at the load end.
Note: Operation begins after about three seconds since the AC
power is supplied.

Display and Alarm Output Functions and Operating Procedures
S8VS-@@@24A@@ models (with display monitor) can display the output voltage, output current, peak hold current, or maintenance forecast
monitor time. S8VS-@@@24B@@/S8VS-@@@24BE@ models (with display monitor) can display the output voltage, output current, peak hold
current, or total run time.
Mode Change
Note: No setting mode is provided for the S8VS-06024@.
Operation Mode
Various states of the Power Supply are indicated.
Note: 1. The peak hold current starts measuring the current 3 seconds after the Power Supply is started. Inrush current is thus not measured.
2. For the factory setting, the output voltage will be displayed when the power supply is first turned ON. Thereafter, the output voltage will
be indicated in the same display when shutting down.
Setting Mode (Except for S8VS-06024@)
Set various parameters of the Power Supply.
Note: 1. Press and hold the (9) Up Key U or (10) Down Key D for two seconds or more to increase or decrease the value rapidly.
2. The S8VS-06024@ is not provided with the setting mode and its parameters are fixed at the shipment setting.

This indicator lights when the output voltage lowers.
Note: 1. When the voltage is restored to the set value or higher and
the Key is pressed at the a01 display to return to the
output current display, the a01 alarm will be cleared and the
normal output display will return.
2. The above displays are for models with a maintenance

Self-Diagnostics Function
Numbers in the following table indicate the number used in Nomenclature on pages 15 and 17.
Note: 1. External noise is probable as a cause of “---”, “e01”, “e02”, “e03”, “e04”, and “e05” errors.
2. Operation out of the derating curve area, ventilation error, and incorrect mounting direction are probable as a cause of “h\t” error.
3. If the “h\t” error state continues for more than three hours, the maintenance forecast monitor function becomes invalid. The Yrs output
(Maintenance forecast output terminal (Yrs)) will remain OFF (no continuity).
Replace the power supply if this condition occurs even if the output is correct, as internal parts may be deteriorated.

Maintenance Forecast (S8VS-@@@24A@@)
Displays when the maintenance forecast has reached the set value.
Indication and Outpu t
When the Product is purchased, “ful” will be indicated. As
electrolytic capacitors deteriorate, indication changes to “hlf” (Refer
to page 30). “ful” will be indicated for the maintenance forecast
display for approximately one month after the Power Supply is first
turned ON. The accumulated value will then be displayed depending
on the ambient conditions thereafter. (However, the “hlf” indication
may not appear, depending on the usage environment and the set
value for maintenance forecast.)
S8VS-06024A:
After the remaining time to maintenance is reduced to less than two
years, indication automatically changes to a value, which decreases
from “1.5” to “1.0” to “0.5” to “0.0” (year) as the running hours
increase. If the remaining time becomes less than 0.5 year, an alarm
(a02) and “0.0” are indicated alternately.
S8VS-09024A@@/S8VS-12024A@,
S8VS-18024A@/S8VS-24024A@/S8VS-48024A:
If the maintenance forecast setting L (which can be set arbitrarily from
0.0 to 5.0 years in 0.5-year steps) is set to a value larger than two
years, the indication automatically changes to a value (L - 0.5) after
the remaining time to maintenance is reduced to the set years, and an
alarm (a02) and the remaining time are indicated alternately.
If the setting is less than 2.0 years, the indication changes to a value
(1.5) after the remaining time becomes less than two years, and after
the remaining time becomes less than the set time, an alarm (a02)
and the remaining time (L - 0.5) are indicated alternately.
If the alarm (a02) and a numeric value are indicated alternately, a
transistor (maintenance forecast output terminal (Yrs)) will turn OFF
to indicate the need for maintenance. (The transistor turns OFF when
the maintenance forecast time is reached, i.e., there will be no
continuity at the maintenance forecast output terminal.)
Note: 1. The remaining time to maintenance is based on continuous
operation, not including the time when the power supply is
turned OFF.
2. “ful” will be indicated until approximately one month of
time is accumulated to estimate the speed of deterioration
and the output will remain ON (continuity at the
maintenance forecast output terminal (Yrs)).

Maintenance Forecast Monitor Function
The Power Supply is equipped with electrolytic capacitors.
The electrolyte inside the electrolytic capacitor penetrates the sealing
rubber and evaporates as time passes since it is manufactured, which
causes deterioration of characteristics such as decreasing the
capacitance, etc.
Due to this deterioration of the characteristics of the electrolytic
capacitor, the Power Supply decreases its performance as time
passes.
The maintenance forecast monitor function shows an approximate
period left for maintenance of the Power Supply due to deterioration
of electrolytic capacitors. When the period left for maintenance that
the power supply forecasts reaches the set value, an alarm is
indicated and an output signal is triggered.
Use this function to know the approximate replacement timing of the
Power Supply.
Note: The maintenance forecast monitor function indicates an
approximate period left for maintenance, based on
deterioration of the electrolytic capacitor. It does not predict
failures caused by other reasons.
Relationship between Indicated Values and Output of Set Values
Principle of Operation
The deterioration speed of the electrolytic capacitor varies
considerably according to the ambient temperature. (Generally the
speed follows “Rule of Two for every 10°C”; for every 10°C increase
in temperature the rate of degradation doubles according to
Arrhenius’s equation.) The S8VS-@@@24A@@ monitors the
temperature inside the power supply, and calculates the amount of
deterioration according to the running hours and inside temperature.
Judging by this amount of deterioration, the power supply will give the
alarm indication and output when the period left for maintenance
reaches the set value.
Note: 1. Due to degradation of internal electronic parts, replace the
power supply approximately 15 years after purchase even if
indication and output of maintenance forecast monitor are
not issued.
2. The maintenance forecast is accelerated or decelerated
according to operating conditions. Periodically check
indication.
3. Acceleration or deceleration of the maintenance forecast
may cause the output to repeatedly go ON/OFF.
Only the S8VS-09024A@@, S8VS-12024A@, S8VS-
18024A@, S8VS-24024A@, and S8VS-48024A are
equipped with output.
4. The accuracy of the maintenance forecast function may be
adversely affected by applications in which the AC input is
frequently turned ON/OFF.
Reference Values (15-W to 480-W Models)
Note: The maintenance forecast is the service life (the power
supply’s internal temperature is monitored at all times) of the
internal electrolytic capacitor in actual operating conditions,
and varies according to the customer’s operating conditions.
15 years is taken as the maximum period of the maintenance
forecast.

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 (15- and 30-W models: 0.8 to
1.0 N·m/60-, 90-,120-, 180-, 240-, and 480-W models:
1.08 N·m).
Minor injury due to electric shock may occasionally
occur. Do not touch the terminals while power is
being supplied. Always close the terminal cover after
wiring.
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.
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 use in locations where the ambient temperature exceeds the
range of the derating curve.
•When cutting out holes for mounting, make sure that cuttings do
not enter the interior of the Products.
15-W and 30-W Models
•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.
•Use a mounting bracket when the Product is mounted facing
horizontally.
•Heat dissipation will be adversely affected. When the Product is
mounted facing horizontally, always place the side with the label
facing upward.
•Operate the Power Supply within a range that is 5°C less than the
values in the derating curve in Engineering Data on page 18 if the
Power Supply is used with an installation spacing of 10 mm min.
(20 mm max.) on the left and right.
60-W, 90-W, 120-W, 180-W, 240-W, and 480-W Models
•Improper mounting will interfere with heat dissipation and may
occasionally result in deterioration or damage of internal parts. Use
the standard mounting method only.
•The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation. Do not loosen the screw on the side face
of the main body.
Wiring
•Connect the ground completely. A protective earthing terminal
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.
•When wiring a screwless terminal block, do not insert more than
one wire into a single terminal.
•When using a screwless terminal block, connect or disconnect the
I/O wire to each terminal while inserting an appropriate tool, such
as a flat-blade screwdriver, into the tool insertion hole. Make sure
that the wire is securely connected to the terminal after wiring. Do
not insert wires into the tool insertion holes.
If a wire is not inserted far enough or if it is loose, electric shock,
fire, or equipment failure may occur. Strip the wires according to
specifications. Insert an appropriate tool, such as a flat-blade
screwdriver, into the tool insertion hole, insert the wire until the
stripped portion is no longer visible, and then remove the tool.
Make sure that the wires are securely connected to the terminal
block after wiring. Never insert wires into the tool insertion holes.
•Use the following material for the wires to be connected to the
S8VS to prevent smoking or ignition caused by abnormal loads.

•Strip I/O wires for 11 mm when using a screwless terminal block.
*The rated current for output terminals is 10 A per terminal. Be sure
to use multiple terminals simultaneously for current that exceeds
the terminal rating. When applying a current of 10 A or more, use at
least two terminals each for the positive and negative wires.
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 cut in half 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%.
•Do not use the Power Supply in areas outside the derating curve
otherwise, internal parts may occasionally deteriorate or be
damaged.
•Use the Power Supply at a humidity of 25% to 85%.
•Do not use the Power Supply in locations subject to direct sunlight.
•Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of Products.
S8VS-@@@24A@@ Models only
Satisfy the following conditions when storing the Power Supply for
long periods of time to maintain its remaining service life function.
When storing for more than three months, store within an ambient
temperature range of −25 to +30°C and the humidity range of 25% to
70%.
Periodic Check for Models with Indication
Monitor Except 60-W Models
It may take from several years to more than 10 years under general
operating conditions for the power supply to output the maintenance
forecast monitor alarm (S8VS-@@@24A@@). The total run time
monitor (S8VS-@@@24B@@/S8VS-@@@24BE@) may be a similar
number of years as the maintenance forecast monitor according to
some settings. During operation over an extended period of time,
periodically check if the maintenance forecast monitor output (Yrs) or
total run time monitor output (kh) is correctly functioning by the
following procedure.
1. Select the operation mode.
2. Check that the output (Yrs/kh) is turned ON (with continuity).
3. In the operation mode, press and hold the Down Key D (10) and
the Mode Key M (8) simultaneously for at least three seconds.
The main display (6) changes to “a02.”
An inactive output (Yrs/kh) (no continuity) in the “a02” indication
indicates the correct function.
4. Release keys to return to the regular state.
Note: DC output stays ON during the periodical check.
Overcurrent Protection
•Internal parts may possibly deteriorate or be damaged if a
short-circuited or overcurrent state continues during operation.
•Internal parts may possibly deteriorate or be 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.
•The DC ON indicator (green) flashes if the overload protection
function operates.
Alarm Output for Models with Indication Monitor

DIN Rail Mounti ng
To mount the Block on a DIN Rail, hook portion (A) of the Block onto
the rail and press the Block in direction (B).
To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.
Series Operation
(24-V Model)
Two power supplies can be connected in series.
Note: 1. The diode is connected as shown in the figure. If the load is
short-circuited, a reverse voltage will be generated inside
the Power Supply. If this occurs the Power Supply may
possibly deteriorate or be damaged. Always connect a
diode as shown in the figure.
Select a diode having the following ratings.
2. Although Products having different specifications can be
connected in series, the current flowing through the load
must not exceed the smaller rated output current.
3. Serial operation is not possible with 5-V and 12-V models.
Making Positive/Negative Outputs
•The outputs are floating outputs (i.e., the primary circuits and
secondary circuits are separated). You can therefore make
positive and negative outputs by using two Power Supplies.
You can make positive and negative outputs with any of the
models.
If positive and negative outputs are used, connect Power Supplies
of the same model as in the following figure. (Combinations with
different output capacities or output voltages can be made.
However, use the lower of the two maximum rated output currents
as the current to the loads.)
•Depending on the model, internal circuits may be damaged due to
startup failure when the power is turned ON if loads such as a
servomotor or operational amplifier may operate in series.
Therefore, connect bypass diodes (D1, D2) as shown in the
following figure.
If the list of models that support series connection of outputs says
that an external diode is not required, an external diode is also not
required for positive/negative outputs.
•Use the following information as a guide to the diode type, dialectic
strength, and current.
Parallel Operation
The Product is not designed for parallel operation.
Backup Operation
•
B
ackup operation can be performed. Backup operation provides
protection by using an extra Power Supply even if the output
current is sufficient with one Power Supply. If one of the Power
Supplies fails, the second Power Supply still provides sufficient
power.
Use the same model for Power Supplies A and B.
•Use a load capacity that can be supplied by either Power Supply A
or Power Supply B alone.
•If backup operation is used, be sure to connect a diode to both
Power Supply A and Power Supply B as shown in the above figure
so that the backup Power Supply is not affected by a failed Power
Supply.
Use the following information as a guide to the diode type, dialectic
strength, and current.

•Increase the output voltage setting of Power Supply A and Power
Supply B by the drop in the forward voltage (VF) of diodes D1 and
D2.
Also, the diodes will cause a power loss equivalent to the Power
Supply output current (IOUT) times the diode forward voltage (VF).
Therefore, cooling measures must be implemented so that the
temperature of the diodes decreases to the catalog value or lower.
•Because of the load power and power loss due to the diodes, do
not exceed the rated power of one Power Supply (rated output
voltage x rated output current).
In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the power supply.
In case there is no output voltage, please check the following points
before contacting us:
•Checking overload protected status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
•Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least
3 minutes. Then turn it ON again to see if this clears the condition.
Audible Noise at Power ON
(120-W, 180-W, 240-W, and 480-W Models)
A harmonic current suppression circuit is built into the Power Supply.
This circuit can create noise when the input is turned ON, but it will
last only until the internal circuits stabilize and does not indicate any
problem in the Product.
