Overvoltage Protection
(A) Standard (Vertical) mounting
(B) Face-up mounting
Overload Protection
Output voltage (V)
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.
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 five minutes and then turning it back ON again.

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,
12
W
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.
S8VK-T
Mounting
Power Boost Function
• 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.
*1
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

Overload 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.

Load
• 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.
• 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.
• Power Boost Function is not possible for the S8VK-T 960 W at
2-phase input or in parallel operation.

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.

Schottky Barrier diode
Dielectric strength (VRRM) Twice the rated output voltage or above

• 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.
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.
Two Power Supplies can be connected in parallel.
1. Parallel operation is possible only if the standard mounting and
3-phase input is used.
Maintain an ambient temperature of between -25 and 40•C.
2. For parallel operation, always use two Power Supplies with the
same capacity.
3. Use the output voltage adjusters (V. ADJ) to adjust the difference
in the output voltages between the two Power Supplies to 50 mV
or less.
4. If the output current from the two Power Supplies is not balanced,
the Power Supply with the higher output voltage will operate in an
overcurrent protection state, which will extremely reduce its
service life. After you adjust the difference in the output voltages
between the two Power Supplies, make sure that the currents are
well balanced.
5. The length and thickness of each wire connected to the load and
each unit must be the same so that there is no difference in the
voltage drop value between the load and the output terminals of
each Power Supply.
6. For Parallel Operation with units 120 W, 240 W S8VK-T Power
Supplies, connect diodes or S8VK-R to the outputs of each unit if
sudden load variation influence occurs in the ambient operation
environment.
Refer to the S8VK-R datasheet (Catalog No.: T059) for S8VK-R
specifications and the model number for each capacity.

Backup Operation
In Case There Is No Output Voltage
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 for 120 W, 240 W, and
480 W.
Refer to the S8VK-R datasheet (Catalog No.: T059) for S8VK-R
specifications and the model number for each capacity.
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
5 minutes. Then turn it ON again to see if this clears the condition.

• 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 × rated output current).

The product warranty is valid for a period of three years from the date of shipment from the factory.
Terms of Warranty
The warranty is valid only for the following operating conditions.
1. Average ambient operating temperature of the product: 40°C max.
2. Average load rate: 80% max.
3. Mounting method: Standard mounting
* The maximum ratings must be within the derating curve.
If the product fails for reasons attributable to OMRON within the above warranty period, OMRON will repair or replace the faulty part of 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.
(1) Failures that result from handling or operation of the product under conditions or in environments that are not given in this document and
not given in any other specifications exchanged between OMRON and the customer
(2) Failures that originate in causes other than the delivered product itself
(3) Failures caused by disassembly, modification, or repair of the product by anyone other than OMRON

(6) Failures caused by other causes for which OMRON is not responsible, such as natural disasters and other acts of God
This warranty is limited to the individual product that was delivered and does not cover any secondary, subsequent, or related damages.
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. (The fan is excluded for models with fans.)
This product model is designed with a service life of 10 years minimum under the above conditions.
