9.1 Method A: Using two external variable DC voltage sources
Remote Socket Pin Assignment for external variable voltage source
PIN FUNCTIONS REMARKS
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
6 N.A.
7 N.A.
8 N.A.
9. Analogue Remote Control Mode
There are two methods for remote control of current and voltage adjustment.
NOTE: Both methods require both the current remote control part and the volt-
age remote control part to be set up and be in-use at the same time in order for
analogue remote control mode to be functional. Otherwise unit will be in CC mode
all the time and the analogue remote control will not be functional.
CC current setting by remote control.
Short circuit the main output with 12AWG wire.
Adjust the CC current using external power supply connected to Pin 3.
Output voltage setting by remote control.
Check the output voltage range of the power supply by varying the external
voltage source connected to Pin 2.
