*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.

S8VK-WA Specifications 3

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, EN/IEC 61204-7
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 or
EN/IEC 61204-7.
• Safety Standards for a DC Input
＜S8VK-WA240, 380, 960＞
The following safety standards apply to a DC input: UL 62368-1, cUR (CSA C22.2 No. 62368-1), EN/IEC 62368-1,
EN/IEC 62477-1, EN/IEC 61558-2-16
＜S8VK-WA202＞
The following safety standards apply to a DC input: UL 62368-1, cUR (CSA C22.2 No. 62368-1), EN/IEC 62368-1,
EN/IEC 62477-1, EN/IEC 61204-7.
Safety standard compliance is achievable by connecting a safety standard certified fuse to the (L1/+) side.
For a DC power input, connect (L1/+) side to (+), and (L3/-) side to (-).
To select a safety standard fuse, refer to Recommended circuit breakers and fuses on Data Sheet.

 

Inrush Current, Startup Time, and Output Hold Time

S8VK-WA Specifications 5

 

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 overload protection circuit will protect the product from short-circuit currents and overcurrents.

＜S8VK-WA240, 480, 960＞ *1 *2

When the load current reaches 151% to 175% of the rated current, the output voltage is automatically lowered. When the overload status is cleared, the output voltage is automatically recovered to the normal status.

＜S8VK-WA202＞ (switch for parallel operation: SINGLE) *1 *2 *3

 

When the load current reaches 151% to 175% of the rated current, the output voltage is automatically lowered. When the overload status is cleared, the output voltage is automatically recovered to the normal status.
The output voltage is cut off under the following conditions.
• A current exceeding the rating continues for more than 5 seconds
• The overload status continues for three seconds or longer while the output voltage is lowered due to overload protection
To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

 

＜S8VK-WA202＞ (switch for parallel operation: PARALLEL) *1 *2 *3

 

When the load current reaches 81% to 110% of the rated current, the output voltage is automatically lowered. When the overload status is cleared, the output voltage is automatically recovered to the normal status.
The output voltage is cut off under the following conditions.
• The overload status continues for three seconds or longer while the output voltage is lowered due to overload protection.
To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

 

S8VK-WA Specifications 10
S8VK-WA Specifications 11

 

*1. Internal parts may occasionally deteriorate or be damaged if a short-circuited or overload status continues during
operation. Use the product after verifying that the Iout > 100% indicator is not lit or the Iout>100% signal output is OFF.
*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.
*3. Do not turn ON the power again until the cause of the overvoltage has been removed.

 

＜Only S8VK-WA20224＞ (for terminal block)

If use continues for longer than 10 seconds while a current exceeds a 45 A output current for each terminal of output, overload protection is activated. The maximum current of each terminal is limited so that it will be 45 A or lower and the output voltage is also lowered.
When the overload status is cleared, the output current and the output voltage are automatically recovered to the normal status.
The output voltage is cut off when the overload status continues for three seconds or longer while the output voltage is lowered due to overload protection. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

S8VK-WA Specifications 13

 

Note: 1. The rated current per pole of the output terminals will be 45 A.
If a current exceeding 45 A will flow, wire using multiple poles at the same time.
2. If overload protection is activated for even one output terminal pole, the output voltage of all terminals will be
lowered.
3. Make the length and thickness of the wires connected to the load the same so that the current flowing through
them will be the same.

 

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. (Other than S8VK-
WA202)

 

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.
