• Manufacturer Part Number: HRPG-450-2.5
• Description: 450W Single Output with PFC Function
• Manufacturer: MEANWELL [Mean Well Enterprises Co., Ltd.]

Function Description of CN100
Function Manual
1.Remote Sense
2.DC-OK Signal
3.Remote Control
The remote sensing compensates voltage drop on
the load wiring up to 0.5V.
DC-OK signal is a TTL level signal. High when PSU turns on.
The PSU can be turned ON/OFF by using the
"Remote Control" function.
Pin No. Function Description
Between DC-OK(pin5) and GND(pin6)
3.3 ~ 5.6V
0 ~ 1V
Between RC+(pin1) and RC-(pin2)

450W Single Output with PFC Function
Turns the output on and off by electrical or dry contact between pin 2 (RC-), Short: Power OFF, Open: Power ON.
Remote control ground.
Auxiliary voltage output, 4.75~5.25V, referenced to pin 4(AUXG). The maximum load current is 0.3A. This output has the built-in oring
diodes and is not controlled by the "remote ON/OFF control".
Auxiliary voltage output ground. The signal return is isolated from the output terminals (+V & -V).
This pin connects to the negative terminal(-V). Return for DC-OK signal output.
Positive sensing. The +S signal should be connected to the positive terminal of the load. The +S and -S leads should be twisted in pair to
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
Negative sensing. The -S signal should be connected to the negative terminal of the load. The -S and +S leads should be twisted in pair to
minimize noise pick-up effect. The maximum line drop compensation is 0.5V.
