Omron, S8VK-WB Series

Saving Space and More-advanced Control Panels

Harmonized design and side-by-side mounting help delivering more compact control panels with additional functionality.

Uniform height reduces dead space and enables control panel downsizing

The switch mode power supply, noise filter, and DC electronic circuit protector, all compliant with the “Value Design for Panel” concept, are made to be uniform in height to reduce dead space and enable control panel downsizing.

Shortening Lead Time for Control Panel Building

With its extensive product lineup and features such as electrical control CAD support and status visualization, the S8VK Series helps streamline processes in building equipment and control panels.

[Design]

Extensive array of products with different input specifications and capacities significantly reduces selection effort

The S8VK Series offers both models with single phase (200-240 V) input and those with the more popular high-capacity three-phase input, allowing you to significantly reduce selection effort: just select a product with the input voltage and capacity best suited for your purpose.

eCAD library provided for all models greatly reduces design work

OMRON provides the libraries for over 48,000 models*4, highest in the industry, to achieve the great reduction of works for electrical design drawing and data creation.

*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 is determined according to the Electrical Appliances and Material Safety Act.
*4. Values for a cold start at 25°C. Refer to Inrush Current, Startup Time, and Output Hold Time on below.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 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. The value is when both rated output voltage and rated output current are satisfied.
A characteristic when the ambient operating temperature is 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.

Standard Compliance

• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a protective
earth (PE).
• EN/IEC 61558-2-16
The S8VK-WA 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 complies with EN/IEC 61558-2-16.
• For the S8VK-WB, the DC input is not compliant with Safety standards.
• Only 480 W and 960 W models are compliant with BIS (IS 13252 (Part 1)).

Inrush Current, Startup Time, and Output Hold Time

Note: Twice the normal inrush current will flow during parallel operation or for backup operation. 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.

Overload Protection

The product is automatically protected from short-circuit current and overcurrent damages when the load current is in the range of 151 to 175% of the rated current.
When the output current falls within the rated range, the overload protection function is automatically cleared.

Note: 1. Internal parts may occasionally deteriorate or be damaged if a short-circuited or overcurrent state continues during
operation. Be sure to check that the Iout > 100% indicator is not lit or the Iout > 100% signal output is turned OFF
before using.
2. Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with inrush
current or overloading at the load end. Do not use the Power Supply for such applications.

Overvoltage Protection

Overvoltage will be detected to prevent the load from being subjected to excessive voltage when the feedback circuit in the Power Supply fails, etc.
When an excessive voltage that is approximately 130% of the rated output voltage or more is output, the output voltage is cut OFF, preventing damage to the load due to overvoltage.
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.

INPUT OK Indicator

The INPUT OK indicator will light when the input voltage exceeds the lower limit value of the permissible range.
Note: The voltage may be applied even if the indicator does not light.
Be sure to check the input voltage when performing wiring.

DC OK Indicator/Signal Output

The DC OK indicator will light when the output voltage is more than 90% of the rated output voltage, and the internal MOS FET relay is conducted (turned ON).
Note: 1. The output voltage may be generated even if the indicator does not light. Be sure to check the output voltage when
connecting to the load.
2. This function monitors the voltage at the power output terminals.
To check the voltage accurately, measure the voltage at the load end.
3. If the output voltage is set to less than 90% of the rated output voltage, the indicator may go off and the signal
output may be turned OFF.

Iout > 100% Indicator/Signal Output

The Iout > 100% indicator lights up when the output current exceeds the rated output current, and the internal MOS FET relay is conducted (turned ON).
Note: 1. The Iout > 100% Indicator may light up, and the Iout > 100% Signal Output may turn ON during peak current
operation, however, the Power Supply can be used as long as the operating conditions specified in Peak current
(Data Sheet) are satisfied.
2. Even when the operating conditions for parallel operation are satisfied, the Iout>100% Indicator / Signal Output
may operate, so do not use the Iout>100% Indicator / Signal Output.
3. During a short-circuit, the indicator will operate intermittently due to the overload protection function. When this
happens, the indicator will blink in accordance with the intermittent operation, and the Iout > 100% signal output
will repeated turn ON and OFF.
The shortest ON time of the Iout > 100% signal output during intermittent operation is 5 ms.

Specifications of the Signal Output Terminals (between DC OK Signal Output Terminal and COM Terminal, and between Iout > 100% Signal Output Terminal and COM Terminal)

Since the Signal Output is composed of the MOS FET relay, it does not have any polarity.
30 VDC max., 50 mA max.
Residual voltage when the function is ON: 2 V max.
Leakage current when the function is OFF: 0.1 mA max.
Note: 1. Internal current control circuits are not provided internally for output signals. Do not allow the output current to
exceed 50 mA.
2. After completing wiring, confirm that the circuits operate correctly.

Identification of error locations at the input, product, and load side by the Indicator or Signal Output, and troubleshooting for the same (Maintenance point indicator)

Error locations at the input, product, and load side can be identified by the INPUT OK, DC OK, Iout > 100% Indicator / Signal Output.
