2-2. CN1 Connector Pin Configuration and Function
Pin
No.
Configuration Function
1 DC_OK DC_OK signal is an open collector output signal,
referenced to pin2 (COM). As the output voltage
drops,
DC_OK signal will output “High”.
2 COM Return loop for DC_OK signal.
3 5VSB Auxiliary voltage output, 4.75~5.25V, referenced to
pin4 (COM). The maximum load current is 0.3A. This
output is not controlled by the remote ON/OFF control.
4 COM Return loop for 5VSB signal.
5 CNT+ Remote ON/OFF control terminal
(When CNT+ is pulled to TTL low, power supply unit
turns ON. Otherwise, it turns OFF)
6 CNT- Return loop for CNT+ signal
7 PV Output voltage external control terminal
8 COM Return loop for PV signal.
