*1 180 Vac to 252 Vac for 200 Vac input, 342 Vac to 504 Vac for 400 Vac input. At the constant load. *2 The amount of change that occurs when the load is changed from no load to full load (rated output power/rated output voltage) with rated output voltage. The value is measured at the sensing point. *3 The amount of time required for the output voltage to return to a value within the rated output voltage ± (0.1 % + 10 mV) when the response setting of the CV mode is FAST. The load current fluctuation is 50 % to 100 % of the maximum current with the set output voltage. *4 In the case where the CV mode response setting is FAST and having the rated output current. Values measured using JEITA RC-9131C probe and 100:1 probe. *5 Measurement frequency band: 10 Hz to 20 MHz *6 Measurement frequency band: 10 Hz to 1 MHz *7 Applicable to the case where the CV mode response setting is FAST and the rated output voltage changes from 10 % to 90 %. *8 For a pure resistance. *9 Applicable to the case where the CV mode response setting is FAST and the rated output voltage changes from 90 % to 10 %.
