(*1) At Maximum Output Power, nominal input voltage, Ta = 25
°C
.
(*2) For cases where conformance to various safety specs ( UL, CSA, EN ) are required, to be described as 100 - 240VAC, 50 / 60Hz on name plate.
(*3) Not applicable for the in-rush current to Noise Filter for less than 0.2mS.
(*4) Ripple & noise are measured at 20MHz by using a 300mm twisted pair of load wires terminated with a 0.1uF film capacitor and a 47uF
electrolytic capacitor.
(*5) Measure line & load regulation at output terminal M3 tapped point.
(*6) 88 - 264VAC, constant load.
(*7) No load - Full load (Maximum power ), constant input voltage.
(*8) Current limit with automatic recovery.
Avoid to operate at overload or dead short for more than 30 seconds.
(*9) Over voltage clamp by zener diode, hiccup mode.
(*10) Measured by each measuring method of UL and EN (at 60Hz), Ta = 25
°C
.
(*11) Refer to Output Derating Curve (PA580-01-02_) for details of output derating versus ambient temperature.
(*12) All parameters NOT specifically mentioned are measured at 230VAC input, rated load and Ta = 25
