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 Catalog 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 Catalog 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 Catalog 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  Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.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 62368-1, cUR (CSA C22.2 No. 62368-1), EN 50178, EN 62368-1 and Lloyd’s.
  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).
