3. Alarm

48V DC Input Voltage Industrial Power Supplies 400W Output Power GPDD401M28-1A

Item Yes/No Technical index Note
Power failure alarm signal

Yes

Input: normal, output: low impedance;

Input: failure, output: high impedance;

 When DC input fails, alarm signal of +28V output at full load rise to +2.2V, (need to add pull-up resistor when test). Time interval for +28 V falling to +15V shall not be less than 1 ms.
Input normal LED display

Yes

 Use indicator light (red): red light turn on means input is normal
Output normal LED display

Yes

 Use indicator light (green): green light turn on means output 28V is normal
