GW Instek PSU 6-200 - External Voltage Control of Current Output

ANALOG CONTROL
121
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 108 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)
Connection
When connecting the external voltage source to
the connectors, use shielded or twisted paired
wiring.
