Method A:
Using Voltage Source
A variable external voltage source of 0
–
5 V is fed into the remote control terminal to adjust the output
voltage level.
Warning:
Do not input higher than 5 V, otherwise the Over Voltage Protection (OVP) will be triggered.
1. Make sure the load is disconnected and the power supply is OFF.
2. Use only wires from port 2 and 4. Then, connect port 2 to positive polarity of the external voltage
source and port 4 to negative polarity of the external voltage source.
3. Switch on the power supply.
4. Vary the external input voltage 0
–
5 V to check and verify for the full output voltage range of
power supply.
5. Switch off the power supply.
Method B:
Using 5 k
Variable Resistor
1. Make sure the load is disconnected and the power supply is OFF.
2. Prepare a 5 k
variable resistor and use wires from port 1, 2 and 4.
3. Switch on the power supply.
4. Adjust the 5 k
variable resistor from one end to other end to check and verify for the full output
voltage range of power supply.
5. Switch off the power supply.
