*1. When a load is connected that has a built-in DC-DC converter, the overload protection may operate at startup and the
      Power Supply may not start. Refer to Overload Protection on Catalog.
*2. Do not use an Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but
      the rise in the internal temperature of the Power Supply may result in ignition or burning.
*3. Rated input voltage: 100 or 200 VAC at 100% load.
*4. Output characteristics: Specified at power supply output terminals.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than the allowable voltage range.
      When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that load is
      not damaged.
*6. For details, refer to Overload Protection on Catalog.
*7. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
*8. The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).
*9. The weight is of the type without a mounting bracket.
*10.S8JX-P600[][]CD: 100 m/s2
*11.The noise value will vary depending on wiring methods and other characteristics.
      300-W/600-W models conform to Class B with an aluminum plate set under the product.
      For the 300-W 5V and 600-W 5V and 12V models, insert a noise filter (TDK-Lambda RSEN-2016) in the input line.
*12.Measurement method conform to RC-9131A of the JEITA standards. For details, refer to "Ripple Noise Voltage" on
*13.Applicable to the 300-W/600-W 5V and 12V models
