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 |
 |
| Remote on/off : Shorting Pin 3 to Pin 4 enables main output while keeping the Pins open disables main output. | |
