System-Related Functions

– Negative current limit setting (I_Lim-): Connect an external DC power

supply capable of outputting 0V ~ 10V between pin 15 (Cur_Pro) and pin

3/4/5/6 (AGND) of the analog interface.

• CC priority mode

– Current setting: Connect an external DC power supply capable of output-

ting –10V ~ 10V between pin 15 (Cur_Pro) and pin 3/4/5/6 (AGND) of the

analog interface.

– High voltage limit (V_High): Connect an external DC power supply capa-

ble of outputting 0V ~ 10V between pin 17 (Cur/Vol_Pro) and pin 3/4/5/6

(AGND) of the analog interface.

– Low voltage limit (V_Low): Connect an external DC power supply capa-

ble of outputting 0V ~ 10V between pin 1 (Vol_Pro) and pin 3/4/5/6

(AGND) of the analog interface.

The wiring method is as follows.

• Switch of On/Off state

The On/Off state can be switched remotely through the analog interface.

Connect an external DC power supply capable of outputting 0V and 5V be-

tween pin 8 (On/Off_In) and 21 (GND) of the analog interface. Other analog

input pins should also be connected correctly. The wiring method is shown

in the figure below.
