Efficiency vs Load (48V Model)

• The curve above is measured at 230VAC.

Function Manual

Remote Sense

• The remote sensing compensates voltage drop on the load wiring up to 0.5V.

• The +S signal should be connected to the positive terminal of the load whereas-S signal to the negative terminal.
• By factory default, on CN50, Remote ON-OFF (pin13) and 12V-AUX (pin14), PV(pin5) and PS (pin6), and PC (pin7) and PO (pin8, respectively, are shorted when shipped. The power supply will have no output if the shorting connector is not assembled unless certain functions needs to be activated.

Remote ON-OFF

• The power supply can be turned ON/OFF by using the “Remote ON-OFF” function.

When multiple power supplies need to turn ON/OFF simultaneously by Remote ON- OFF control, -S & -V on CN50, as well as +S & +V, on each power supply should be connected.

Output Voltage Programming (or, PV / remote voltage programming / remote adjust / margin programming / dynamic voltage trim)

In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed to 40~110% of the nominal voltage by applying EXTERNAL VOLTAGE.

• If EXTERNAL VOLTAGE (VDC) <0.5V, the power supply may enter under voltage protection; it needs to be restarted to work.

Caution: By factory default, the Output Voltage Programming is not activated, and PV (pin5) and PS(pin6) are shorted by a connector. Whenever this
function is not needed to activate, as assumed in other sections’ diagrams, please keep PV (pin5) and PS(pin6) shorted; otherwise, the power supply will have no output.

Constant Current Level Programming (or, PC / remote current programming / dynamic current trim)

• The constant current level can be trimmed to 40~110% of the rated current by applying EXTERNAL VOLTAGE.

Caution: By factory default, the Output Current Programming is not activated, and PC(pin7) and PO(pin8) are shorted by connector. Whenever this
function is not needed to activate, as assumed in other sections’ diagrams, please keep PC(pin7) and PO(pin8) shorted; otherwise, the power supply will have no output.

DC_OK signal

• “DC_OK” is an open collector signal. It indicates the output status of the power supply. It can operate in two ways : One is sinking current from external
• TTL signal ; the other is sending out a TTL voltage signal.
• Sinking current from external TTL signal: The maximum sink current is 10mA and the maximum external voltage is 5.6V.
• Sending out TTL voltage signal

10,11| GND| These pins connect to the negative terminal (-V). Return for DC_OK Signal output.
12| G-AUX| Auxiliary voltage output ground.

The signal return is isolated from the output terminals (+V & -V).

13| REMOTE ON-OFF| Turns the output on and off by electrical or dry contact between pin 13 ( ON/OFF) and pin 14 (12V-AUX). Short: Power ON, Open: Power OFF.
14| 12V-AUX| Auxiliary voltage output, 10.8~13.2V, referenced to pin 12(G-AUX).

The maximum load current is 0.1A. This output is not controlled by the “remote ON/OFF control”.
