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

PSU Series User Manual

Isolated External Voltage Control of Current Output
Background
Voltage control of the current output uses the
isolated voltage option (PSU-ISO-V). A voltage
of 0~5V or 0~10V is used to control the full
scale current of the instrument, where:
For 0~5V: Output current = full scale current ×
(external voltage/5)
For 0~10V: Output current = full scale current ×
(external voltage/10)
Connection
When connecting the external voltage source to
the isolated voltage option, use shielded or
twisted paired wiring.
