Power Boost Function

This function is possible when used in combination with S8VK-G (All

Models).

Power Boost is a function that can output the temporary repeated

boost current larger than the rated current.

However, it should meet the following four Boost current conditions.

1. Time that the boost current flows: t1

2. The maximum value of the boost current: lp

3. The average output current: lave

4. The time ratio of the boost current flow: Duty

Note: Boost current conditions

•Do not allow the boost current to continue for more than 10

seconds.

Also, do not let the duty cycle exceed the boost current conditions.

These conditions may damage the Power supply.

•Ensure that the average current of one cycle of the boost current

does not exceed the rated output current.

This may damage the Power Supply.

•Lessen the load of the boost load current by adjusting the ambient

temperature and the mounting direction.

Safety Precautions

Warning Indications

Meaning of Product Safety Symbols

!CAUTION

Risk of a mild burn on rare occasions. Do not touch

the device unit while it is powered on or immediately

after the power is turned off.

The ignition may accidentally be caused. Tighten

terminal screws to a specified torque 4.43 to

5.31 lb-in (0.5 to 0.6 N·m).

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.

Risk of product damage. Do not reverse the polarity

of the device input terminals when wiring.

Risk of internal component deterioration and

damage. Do not connect an AC power supply.

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.

Wiring

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

terminals are wired correctly.

•Increases in the temperature of internal parts resulting from

heating of wiring materials may result in deterioration or damage to

parts. Use wiring materials suitable to the current being used. The

following wiring materials, torque and strip length are

recommended to prevent heating and possible fires in wiring

materials.

•On rare occasions there is a risk of internal element deterioration

and damage if use is continued in a short-circuit or over-current

state.

•Do not apply more than 75N force to the terminal block when

tightening it.

•Use within a range that does not exceed the output current rating.

When a load short-circuit occurs, the short-circuit current of two

power supply units flows. Use output wiring that can handle the

short-circuit current of two units. If the wiring does not have

sufficient current capacity, connect a fuse on the output side.

Recommended fuse S8VK-R10: 15 A, S8VK-R20: 30 A Fast-

acting type

If the current rating of the output terminal is exceeded on the S8VK-

R20, always use multiple terminals simultaneously.

•Risk of damage to internal components. Do not use in a state that

exceeds the rated current of the signal output.

Installation Environment

•Do not use the Redundancy Unit in locations subject to shocks or

vibrations. In particular, install the Redundancy Unit as far away as

possible from contactors or other devices that are a vibration

source.

•Install the Redundancy Unit well away from any sources of strong,

high-frequency noise and surge.

Ambient Operating and Storage Environments

•Store the product with ambient temperature −40 to 85°C, and

relative humidity 0 to 95%.

•The internal parts may occasionally be deteriorated or broken. Do

not use at a temperature that exceed the operating temperature

range for the mounting type.

S8VK-R

Mounting

The long-term reliability of the S8VK-R can be increased by installing

it properly and sufficiently considering heat dissipation.

Install the S8VK-R so that the air flow circulates around it, because

the S8VK-R is designed to radiate heat by means of natural air

circulation.

Can be used in a contact mounting with the S8VK-G (not covered by

safety certification). Two S8VK-G units cannot be mounted together

in a contact mounting.

Input Voltage

Rating

S8VK-R10: DC5 to 30V

S8VK-R20: DC10 to 60V

Input Power Supply Selection

This product contains an internal fuse. If a power supply other than

the S8VK-G is used, the fuse may blow, depending on the state of the

load. Do not connect a power supply other than the S8VK-G to this

product.

If you are building a redundant system, never use in a state that

exceeds the rated current of the power supply. If one of the power

supplies goes down, there is a risk that the voltage on the load side

cannot be attained.

Use the same model for the power supplies that are connected.

On rare occasions internal element deterioration and damage may

occur if use is continued in a short-circuit or over-current state. Do not

continue use for more than 10 seconds.

Do not use in applications where load rush current or overload may

frequently occur. Slight risk of deterioration and damage due to

internal loss.

The signal output / status LED may occasionally not operate stably.

When using in environments where the temperature is less than

−25 °C, always adjust the 5 V power supply to 5.3 V or higher.

Dielectric Strength Test

The S8VK-R is designed to withstand a voltage test of 1 kV AC

between all input/output terminals and the chassis, and 0.5 kV AC

between all input/output terminals and the signal output terminal, for

one minute.

Note:

1. The S8VK-R may possibly be damaged from the impulse voltage

if a testing device switch is used to abruptly apply or shut off 1 kV

AC, 0.5 kV AC. Increase the applied voltage gradually using the

voltage adjustment on the testing device.

2. When testing, always short-circuit all terminals to prevent damage

to the output terminal.

Signal output

Photo switch output

Photo switch ON when input voltage difference is 2.4 V typ. or less.

30 VDC max. (LVLC), 50 mA max., residual voltage when ON: 2 V

max., leakage current when OFF: 0.1 mA max.

Status display LEDs

The status display LEDs show the status of the input power as shown

in the table below.

Redundancy OK

Green on: Input voltage difference is 2.4 V typ. or less.

Voltage balance

Green on: Input voltage difference is 50 mV typ. or less.

The redundancy OK display/signal operates when the voltage

difference is no more than 2.4 V typ. When using a 5 V or 12 V power

supply, verify that there is no difference in the output voltages of the

power supplies.

The voltage balance display does not guarantee current balance. The

degree of balance varies by model, and therefore if you require

operation with balanced current, check the output current of each

power supply unit.

The models below use a voltage balance display, and cannot be used

as a current balance.

S8VK-G015@@

S8VK-G03012·S8VK-G03024

S8VK-G06024

When adjusting the voltage based on the voltage balance, adjust the

voltage of only one power supply. If you must adjust the voltages of

both power supplies, be sure to check the output voltage before use.

If you want to use the voltage balance display to ensure that the

expected life is obtained, use the same thickness and length of wiring

from each S8VK-G to the S8VK-R.

Connections

It is possible to connect S8VK-R like below.

Certain Precautions on Specifications and Use

1. Suitability of Use. Omron Companies shall not be responsible for conformity

with any standards, codes or regulations which apply to the combination of the

Product in the Buyer’s application or use of the Product. At Buyer’s request,

Omron will provide applicable third party certification documents identifying

ratings and limitations of use which apply to the Product. This information by

itself is not sufficient for a complete determination of the suitability of the Prod-

uct in combination with the end product, machine, system, or other application

or use. Buyer shall be solely responsible for determining appropriateness of

the particular Product with respect to Buyer’s application, product or system.

Buyer shall take application responsibility in all cases but the following is a

non-exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii) Use in consumer products or any use in significant quantities.

(iii) Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety equip-

ment, and installations subject to separate industry or government regulations.

(iv) Systems, machines and equipment that could present a risk to life or prop-

erty. Please know and observe all prohibitions of use applicable to this Prod-

uct.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-

ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE

OVERALL EQUIPMENT OR SYSTEM.

2. Programmable Products. Omron Companies shall not be responsible for the

user’s programming of a programmable Product, or any consequence thereof.

3. Performance Data. Data presented in Omron Company websites, catalogs

and other materials is provided as a guide for the user in determining suitabil-

ity and does not constitute a warranty. It may represent the result of Omron’s

test conditions, and the user must correlate it to actual application require-

ments. Actual performance is subject to the Omron’s Warranty and Limitations

of Liability.

4. Change in Specifications. Product specifications and accessories may be

changed at any time based on improvements and other reasons. It is our prac-

tice to change part numbers when published ratings or features are changed,

or when significant construction changes are made. However, some specifica-

tions of the Product may be changed without any notice. When in doubt, spe-

cial part numbers may be assigned to fix or establish key specifications for

your application. Please consult with your Omron’s representative at any time

to confirm actual specifications of purchased Product.

5. Errors and Omissions. Information presented by Omron Companies has been

checked and is believed to be accurate; however, no responsibility is assumed

for clerical, typographical or proofreading errors or omissions.
