used to program or monitor the voltage and current for programming of 0V ~
10V and monitoring of voltage or current value between 0V and parallel full
range.
For example, the analog controls the current with range of 0 ~ 80A. When the
analog signal voltage is set to 5V, the instrument's output or input voltage is set
to 40A; when the analog signal voltage is set to 8V, the instrument's output or in-
put voltage is set to 64A.
Voltage and current setting under the power state
•
CV priority mode
– Voltage setting: Connect an external DC power supply capable of output-
ting 0V ~ 10V between pin 1 (Vol_Pro) and pin 3/4/5/6 (AGND) of the
analog interface.
– Positive current limit setting (I_Lim+): Connect an external DC power
supply capable of outputting 0V ~ 10V between pin 17 (Cur/Vol_Pro) and
pin 3/4/5/6 (AGND) of the analog interface.
– 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.
