GW Instek PSU 100-15 - External Voltage Control of Current Output

ANALOG CONTROL
123
Note
The input impedance for external voltage control is
1MΩ.
Use a stable voltage supply for the external voltage
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 101.
CAUTION
Ensure no more than 10.5V (F-97 = 1) or 5.25 (F-97 =
0) volts are input into the external voltage input.
Ensure the voltage polarity is correct when connecting
the external voltage.
External Voltage Control of Current Output
Background
External voltage control of the current output is
accomplished using the analog control connector
on the rear panel. There are two external voltage
control ranges, 0~5V and 0~10V, depending on the
F-97 configuration. See page 110 for details.
For 0~10V:
Output current = full scale current x (external
voltage/10)
For 0~5V:
Output current = full scale current x (external
voltage/5)
