  • Page 14: Precaution For Use

    4. PRECAUTION FOR USE Never detach the case or panel from this product. Detaching the case or panel may cause damages to this product or electrocution or other dangerous accidents to the use. 1) CHECKING INPUT VOLTAGE ① Keep the permitted range of input voltage. Single phase, 100/120/200/220/ 240 V AC, ±10%, 50/60 Hz.
  • Page 15 2) POWER CORD CONNECTION Some models have a connector retainer on the AC cord connector to hold the cord from slipping off. For safe operation, be sure the retainer is locked. PD18-30AD, PD36-20AD are cannot connect with a commercial AC power inlet because those current ratings are larger than same of the AC power source.
  • Page 16 ② The output lines are floating. Connect either of the front-panel output terminals to GND normally with short bar. 2) ENVIRONMENTAL CONDITIONS ① Keep the operating temperature range of 0℃ to 40℃． It the ambient temperature rises excessively, the device’s protection system works and cuts off power. ②...

    6. OPERATION 6-1. As a Constant-Voltage Power Supply 1) Check the rated input voltage, then connect the power cord. 2) Turn the voltage adjuster knob (VOLTAGE) fully counter-clockwise. 3) Turn on the power switch. The POWER (red) indicator light and the device is operated. Make sure the OUTPUT switch is off (the indicator is out).
