Remote Control Method A: Using two external variable DC voltage sources
A variable external voltage source of 0 ~ 5VDC is fed into the remote control terminal to adjust
the output voltage level.
Warning! Do not input voltage higher than 5V, otherwise the Over Voltage Protection (OVP)
will be triggered.
1. Ensure that the load is disconnected and that the power supply is OFF.
2. Use ONLY the wires from Port 2 (Positive) and Port 4 (Negative)
3. Switch on the power supply.
4. Vary the external input voltage 0~5V to check and verify the full output voltage
range of the supply.
5. Short the main output with 10AWG wire to check the CC display by varying the
external voltage source.
6. Switch OFF the power supply.
