PID-250 Series - 250W Isolated Dual Output PFC Function PSU



A 250W dual output product with isolated outputs and PFC function designed to be used as an open frame or enclosed product. These compact 90~264V switchmode power supplies with active PFC are ideal for 1U installations. The isolated design between CH1 and CH2 can significantly prevent noise sourcing of motor action from entering control circuits and hence secure accurate operation of the end equipment. Accompany with the optional L-Bracket and cover to provide more alternatives to system configuration or solve mounting constraint issues. Other standard functions include remote control for CH1 and short circuit, over load, over voltage and over temperature protections.

Over Load ProtectionCH1: 105 ~ 170%rated output power
Normally work within 10 sec and then shut down, re-power on to recover; >180% rated power
or short circuit, constant current limiting within 10 sec and then shut down, re-power on to recover
Over Voltage ProtectionShut down o/p voltage, re-power on to recover for CH1;
Hiccup mode, recovers automatically afer fault condition is removed for CH2.(by zener diode clamp)
Over Temperature Protection95°C ±5°C Detect on heatsink of power transistor
Shut down o/p voltage, recovers automatically after temperature goes down
Remote ControlCN52 : Open=CH1 & CH2 power on ; Short = CH1 power off, CH2 power on.
when CH2 is malfunction, CH1 will be shut down
