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.
8. 200 to 240 VAC input, in the range of 0 A to the rated output current.
9. This is the value when both rated output voltage and rated output current are satisfied and at room temperature (25°C). Refer to Inrush Current, Startup Time, and Output Hold Time on below for details.
10. At -40 to -25°C, time will be required before the rated output voltage is output after the input voltage is input.
11. MTBF is calculated according to JEITA RCR-9102.
12. Refer to Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance on Data Sheet for details.
13. EN61000-3-2 does not applied to three-phase 200 to 240 VAC input models.
14. Class B compliance was met with the following configuration.

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 Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.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.
• Safety Standards for a DC Input
  The following safety standards apply to a DC input: UL 62368-1, cUR (CSA C22.2 No. 62368-1), EN/IEC 62368-1, EN/IEC62477-1, EN/IEC 61558-2-16. Safety standard compliance is achievable by connecting a UL-certified fuse as specified below to the (L1/+) side. For a DC power input, connect (L1/+) side to (+), and (L3/-) side to (-). To select a UL certified fuse, refer to Recommended circuit breakers and fuses on Data Sheet

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.
