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.
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.
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.
Inrush Current, Startup Time, Output Hold Time
Note: Twice the input current or above will flow during the parallel
operation or redundant system.
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.

Two phases application for Single phase models
For All Single phase Models, S8VK-G
Basically OMRON single phase power supply can be used on two-
phases 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.

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.
•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).
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
• 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.

Series Operation
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.
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.
•Use the following information as a guide to the diode type,
dielectric strength, and current.
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.
8. If you use the 480-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, connect a diode as shown in the diagram.
