*1. The value is when both rated output voltage and rated output current are satisfied.
*2. Do not use an inverter output for the product. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal
temperature of the product may result in ignition or burning.
If the input is connected to a UPS, do not connect a UPS with a square-wave output.
Doing so will cause the internal temperature of the product to increase, possibly causing smoking or burning.
*3. The value for the leakage current is determined according to the Electrical Appliances and Material Safety Act.
*4. Refer to Inrush Current, Startup Time, Output Hold Time on page 12 for details.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 28 V min of the voltage adjustment range. When
adjusting the output voltage, confirm the actual output voltage from the product and be sure that the load is not damaged.
*6. A characteristic when the ambient operating temperature of 25°C.
*7. This is the maximum variation in the output voltage when the input voltage is gradually changed within the allowable input voltage range at
the rated output voltage and rated output current.
*8. 100 to 240 VAC input, in the range of 0 A to the rated output current.
*9. Refer to Overvoltage Protection on page 12 for the time when input voltage shuts off and input turns on again.
*10.At -40 to -25°C, time will be required before the rated output voltage is output after the input voltage is input.
Also, the ripple noise value may exceed the value shown in the above table.
*11.Refer to Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance on page 23 for details.
*12.Refer to Standard Compliance, below.
Standard Compliance
• EN/IEC 61558-2-16
The S8VK-S was designed based on EN/IEC 61558-2-16.
Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.
When certification was received for EN/IEC 60204-1 (Machinery Safety), it was necessary to go through a control transformer to the control
circuits. However, a control transformer is not always necessary for product that have been certified for the safety standard for OVCIII or for
product that use a transformer that conforms to EN/IEC 61558-2-16.
• Safety Standards for a DC Input
The following safety standards are applicable for when a DC input is used: UL 60950-1, cUR (CSA C22.2 No. 60950-1), EN 50178, EN 60950-1, Lloyd's,
and DNV GL.
Safety standard compliance is achievable by connecting a UL-certified fuse as specified below.
Select an external fuse that satisfies the following conditions:
S8VK-S03024: 350 VDC min., 6 A
S8VK-S06024: 350 VDC min., 6 A
S8VK-S12024: 350 VDC min., 8 A
S8VK-S24024: 350 VDC min., 8 A
S8VK-S48024: 350 VDC min., 12 A
• Conformance to Marine Standards
Noise filter “FN2080-10-06” manufactured by SCHAFFNER Corporation. or equivalent should be connected to the Input terminals of S8VK-S
series (Except 60 W).
End Plate (PFP-M) to both sides of the Power Supply to hold the Power Supply in place.
Install clamp filters (“ZCAT2035-0930” manufactured by TDK) on the cables connected to the input and output terminals for 240- and 480-W
models.
• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a protective earth (PE).
• ATEX/IECEx
The Power Supply must be built-in an IP54 enclousure.

Overload Protection
For models S8VK-S03024, S8VK-S06024 and S8VK-S12024, the
output voltage is automatically reduced, and the unit is protected from
short circuit current and overcurrent damage if the load current 121%
to 160% of the rated current. For models S8VK-S24024 and S8VK-
S48024, the output voltage is automatically reduced, and the unit is
protected from short circuit current and overcurrent damage if the
load current 151% to 165% of the rated current.
When the output voltage 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 normal inrush current will flow during parallel operation
or for backup operation. Also, if crossover wiring is used for N
number of Power Supplies, an inrush current of N times the inrush
current for a standalone Power Supply will flow.
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-S
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.
Low-voltage detection output (Only for 240 and
480 W)
Output externally by photo-switch when an output voltage drop is
detected (OFF when an output drop occurs). The detection voltage is
set to about 80% (75% to 90%) of the rated output voltage.
Photo-switch
1. 30 VDC max., 50 mA max. Residual voltage 2 V or less when ON.
Leakage current 0.1 mA or less when OFF.
2. The low-voltage detection output function monitors the voltage of
the output terminal of the power supply.
To check the precise voltage state, measure the voltage of the
load end.
3. If the set voltage is less than 90% of the rated voltage, the low-
voltage detection function may activate.
4. The signal output circuit do not contain current-limiting circuit. Do
not allow the output current to exceed 50 mA.
5. After you complete the wiring, confirm that operation is correct.

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 95% or less.
• 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 95% max.
• 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 Power Supply.
Mounting
• Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Power Supply. 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 Power Supplies.
• The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation. Do not loosen the screws on the Power
Supply.
• The following combinations are possible for (C) Front, Side-by-side
mounting indicated under Mounting on page 12.
• Same models
• S8VK-S03024, S8VK-S06024 and S8VK-S12024
• S8VK-S24024 and S8VK-S48024
Use the Product within the derating curve for the front, side-by-side
mounting.
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.
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.
• When you insert wires or insert a screwdriver into a release hole, do
not press down on the terminal block with a force of 40 N or greater.
• Do not wire anything to the release holes.
• Do not tilt or twist a flat-blade screwdriver while it is inserted into a
release hole on the terminal block. The terminal block may be
damaged.
• Insert a flat-blade screwdriver into the release holes at an angle.
The terminal block may be damaged if you insert the screwdriver
straight in.
• Do not allow the flat-blade screwdriver to fall out while it is inserted
into a release hole.
• Do not bend a wire past its natural bending radius or pull on it with
excessive force. Doing so may cause the wire disconnection.
• Do not insert more than one wire into each terminal insertion hole.
• Do not pre-solder the ends of the wires. Doing so will inhibit proper
connection.
• Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
• Make sure to use stranded wires or wires with ferrules when there
is a possibility of vibration or impact.
• To prevent wiring materials from smoking or ignition, confirm wire
ratings and use the wiring materials given in the following table.
• Input crossover wiring can be used for the input side of this Power
Supply.

●Connecting wires to the Push-In Plus Terminal Block
Part Names of the Terminal Block
Connecting Wires with Ferrules and Solid Wires
Insert the solid wire or ferrule straight into the terminal block until the
end touches the terminal block.
If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wire.
Connecting Stranded Wires
Use the following procedure to connect the wires to the terminal block.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole. The angle should be between 10° and 15°.
If the flat-blade screwdriver is inserted correctly, you will feel the
spring in the release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
insert the wire into the terminal hole until it strikes the terminal
block.
3. Remove the flat-blade screwdriver from the release hole.
Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block.
• If you use a ferrule with a conductor length of 10 mm, part of the
conductor may be visible after the ferrule is inserted into the
terminal block, but the product insulation distance will still be
satisfied.
●Removing wires from the Push-In Plus Terminal
Use the following procedure to remove wires from the terminal.
The same method is used to remove stranded wires, solid wires, and
ferrules.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
remove the wire from the terminal insertion hole.
3. Remove the flat-blade screwdriver from the release hole.

Recommended Flat-blade Screwdriver
Use a flat-blade screwdriver to connect and remove wires.
Use the following flat-blade screwdriver.
The following table shows manufacturers and models as of 2015/Dec.
Power Boost Function
The boost current is a temporary current that exceeds the rated
current.
However, it should meet the following four boost current conditions.
• Time that the boost current flows: t1 10 s
• The boost current: Ip Maximum boost current
• The average output current: Iave Rated output current
• The time ratio of the boost current flow: Duty 30%
• Do not allow a boost current to flow for more than 10 s.
Do not allow the duty to exceed 30%. These conditions may
damage the Power Supply.
• Do not allow the average current for one cycle of the boost current
to exceed the rated current. The Power Supply may be damaged.
• Derate the boost current and the average output current loads
according to the ambient operating temperature and 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.
