Pin Name Type Description
input, the instrument state is switched
to On.
9 Power Digital
output
Indicate the instrument’s loading state:
Under normal loading state, 5V is out-
put; under non-loading state, 0V is
output.
10 CC Digital
output
Indicate the instrument’s working
state: Under the CC mode, 5V is out-
put; otherwise, 0V is output.
11 ALM Digital
output
Indicate the instrument’s fault state: If
the instrument is normal, 5V is output;
if the instrument is abnormal, 0V is
output.

terminal
RS485 interface connection terminal.
14 Vol_MON Analog
output
Monitor the voltage, and output 0 ~
10V voltage value to monitor the DC
terminal voltage between 0 and full
scale.
15 Cur_Pro Analog
input
set current. The input range varies
under different modes.
• When CV is prioritized, input 0 ~
10V voltage value to set the nega-
tive current limit (I_Lim- value) be-
tween 0 and negative full scale;
• When CC is prioritized, input –10V
~ 10V voltage value to set the cur-
rent value between negative full
range and positive full scale;
16 Cur_MON Analog
output
Monitor current. The output range
varies under different modes.
• output –10V ~ 10V voltage value to
monitor the output or absorption
current between negative full range
and positive full scale;
