GW Instek PSU 6-200 - Isolated External Voltage and Current Monitoring

ANALOG CONTROL
153
Note
Use a stable current source for the external current
control.
Note
CV and CC Slew Rate Priority are disabled for V-I
mode (F-03) when using external voltage control.
See the normal function settings on page 99.
CAUTION
Ensure the polarity is correct when connecting the
external voltage.
Ensure no more than 21mA are input into the
external current input.
Isolated External Voltage and Current Monitoring
Background
The isolated analog connector can also be used
to monitor the current (IMON) or voltage
(VMON).
For the isolated voltage option, an output of
0~5V or 0~10V represents the voltage or current
output of 0~ rated current/voltage output.
 IMON = (current output/full scale) × (5 or
10)
 VMON = (voltage output/full scale) × (5 or
10)
For the isolated current option, an output of
4~20mA represents the voltage or current
output of 0~ rated current/voltage output.
 IMON = ((current output/full scale) ×
16mA) + 4mA
 VMON = ((voltage output/full scale) ×
16mA) + 4mA
