Method B: Using a 5 kΩ Variable Resistor
1. Make sure the load is disconnected and the power supply is OFF.
2. Prepare a 5 kΩ variable resistor and connect wires from pins 1, 2, and 3 as
shown in Figure 7 .

3. Turn the remote control ON/OFF switch to ON position.
4. Switch on the power supply.
5. Adjust the 5 kΩ variable resistor from one end to the other to check and
verify the full output voltage range of the power supply.
6. Switch off the power supply.
5.4.2 Enable and Disable the Output
You can use pins 7 and 8 to remotely control the OUTPUT ON/OFF.
a) Open pins 7 and 8 if you want to ENABLE the output (by default).
b) Short pins 7 and 8 if you want to DISABLE the output.
