Mounting

Side mounting is only for S8VK-G015@@.
Use a mounting bracket (S82Y-VK15P, sold separately) when the
product is mounted horizontally.
Heat dissipation will be adversely affected. When the product is
mounted facing horizontally, always place the side with label facing
upward.

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
121% of the rated current.
When the output current returns within the rated range, overload
protection is automatically cleared.

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 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.

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.

Therefore, check the fusing characteristics of fuses and
operating characteristics of breakers making sure that the
external fuses will not burn out and the circuit breakers will not
be activated by the inrush current.

For All Single phase Models, S8VK-G

Basically OMRON single phase power supply can be used on two­phases of a 3–phase-system when some of conditions satisfy like
below.

1. The supplying voltage is below the maximum rated input.
OMRON Power supply allows the input voltage equivalent or less
than 240 VAC+10%.
Please confirm the input voltage between two lines if the input
voltage satisfies this condition before connecting.

2. The external protector is needed on N input line to secure a safety.
N line has no protection of a fuse internally.
An appropriate fuse or circuit breaker should be connected on N
input line like the following.

120 W: 450,000 hrs
240 W: 360,000 hrs
480 W: 230,000 hrs

MTBF stands for Mean Time Between
Failures, which is calculated according to the
probability of accidental device failures, and
indicates reliability of devices.
Therefore, it does not necessarily represent a
life of the product.

The life expectancy indicates average
operating hours under the ambient
temperature of 40°C and a load rate of 50%.
Normally this is determined by the life
expectancy of the built-in aluminum electrolytic
capacitor.

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. For usage onboard a ship, always attach an End Plate
(PFP-M) to both sides of the Power Supply to hold the Power
Supply in place.

• 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 −40 to 85°C and a
humidity of 0% to 95%.

• 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 0% to 95%.

• 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 Products.

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.

To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.

Power Boost Function

For 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

• t1

≤ 10 s

• Ip

≤ Rated boost current

• lave

≤ Rated current

t1

t1 + t2

× 100 [%] ≤ 30%

• 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.

DIN Rail Mounting

To mount the Block on a DIN Rail, hook portion (A) of the Block onto
the rail and press the Block in direction (B).

•

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.

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.

Charging a Battery

If you connect a battery as the load, install overcurrent control and
overvoltage protection circuits.

Output Voltage Adjuster (V.ADJ)

• 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.

Making Positive/Negative Outputs

• The outputs are floating outputs (i.e., the primary circuits and

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.

Type Schottky Barrier diode

RRM) Twice the rated output voltage or above

F) Twice the rated output current or above

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.

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.)

Parallel Operation

Parallel operation is used when the output current from one Power
Supply is insufficient for the load. Power Supplies are connected in
parallel to increase the output current.
The parallel operation of S8VK-G is possible to increase the output
power.
However please consider the following notes when the parallel
operation must be done.

1. The range of ambient temperature for Parallel operation is –25 to
40°C.

2. Up to two of the same model can be connected in parallel.

3. Adjust the output voltage difference of each Power Supply to 50

mV or less, using the output voltage adjuster (V. ADJ).

4. There is no current balancing function for S8VK-G. A high output
voltage unit may work at overcurrent state and in this situation, a
life of a Power Supply will be extremely short.
After adjusting the output voltage, confirm the output current of the
two Power Supplies balances.

5. Using the parallel operation will not satisfy UL1310 Class2 output.

6. For Parallel Operation, to balance the current of the each unit, the

length and thickness of each wire connected to the load and each
unit must be same as much as possible.

7. If you use the 15-W to 240-W S8VK-G in parallel operation, the
output voltage may drop by several volts if the load changes
rapidly (e.g., if the load starts or is disconnected). If operation
becomes unstable, use the S8VK-R as shown in the diagram.
Refer to the S8VK-R datasheet (Catalog No.: T059) for S8VK-R
specifications and the model number for each capacity.

Backup Operation

Backup operation is possible if you use two Power Supplies of the
same model.
Even if one Power Supplies fails, operation can be continued with the
other Power Supply.
Make sure that the maximum load does not exceed the capacity of
one Power Supply.
For backup operation, connect the S8VK-R as shown in the figure.

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, 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.

at the place of purchase or the place where the product delivered without charge.
This warranty does not cover the following types of failures.

Recommended Replacement Periods and Periodic Replacement for
Preventive Maintenance

The recommended replacement period for preventive maintenance is greatly influenced by the application environment of the product. As a
guideline, the recommended replacement period is 7 to 10 years.*
To prevent failures or accidents that can be caused by using a product beyond its service live, we recommend that you replace the product as early
as possible within the recommended replacement period.
However, bear in mind that the recommended replacement period is for reference only and does not guarantee the life of the product.

Many electronic components are used in the product and the product depends on the correct operation of these components to achieve the original
product functions and performance.
However, the influence of the ambient temperature on aluminum electrolytic capacitors is large, and the service life is reduced by half for each
10°C rise in temperature (Arrhenius law).
When the capacity reduction life of the electrolytic capacitor is reached, the product failures or accidents may occur.
We therefore recommend that you replace the product periodically to minimize product failures or accidents in advance.
* The recommended replacement period applies under the following conditions: rated input voltage, load rate of 50% max., ambient temperature

of 40°C max., and the standard mounting method.

This product model is designed with a service life of 10 years minimum under the above conditions.
