  4. 350W with Forced cooling at 100 to 264VAC.
  5. Combine Output Power of Main Output, Fan supply and Standby shall not exceed max power rating
Signals
Power Good : Is a TTL signal which goes high after main output reaches 90% of its set value.
The delay is 0.1 s to 0.5 s
Power Fail : The same signal goes low at least 1ms before main output falls to 90% of set value at AC Power off








Power Good /Power Fail Signal
MULP180
Remote on/off : Shorting Pin 3 to Pin 4 enables main output while keeping the Pins open disables main output.
