REMOTE CONTROL MODE
There are two methods for remote control of current and voltage adjustment.
Both methods require current remote control part to be set up in order for remote control mode to be functional,
otherwise unit will be in CC mode all the time.
9.1 Method
A
Using two external variable DC voltage sources

1
Internal DC +5V
Less then 50mA
2
Voltage Adjust
0 - 5V
3
Current Adjust
0 - 5V
4
Ground
5
Output OFF
Short to Ground

Check the output voltage range of the power supply by varying the external voltage source.
Short circuit the main output with
8AWG
wire to check the display for CC setting varying the external voltage source.
9.2 Method
B
Using two 0 – 5K Ohm variable resistors
Remark: variable resistors 5Kohm.
