(*1)Conditions：Ta=25 degree C　Typical value at maximum output power （Inrush current value doesn't include part of within 0.1msec to input filter)
(*2)The typical ripple voltage in the standard specification is a value measured using 100MHz oscilloscope in the anechoic chamber under the JEITA measuring method(Condition：Ta=25℃,Vin=100Vac Typical value at rated output)
(*3)Upon over voltage or over current conditions, input power must be removed to allow unit reset to occur within a few minutes.
(*4)Derating is required by operating temperature. Follow the overload and specification in manual to avoid the damage of power supply.
