GW Instek PSU 150-10 - Isolated External Voltage Control of Voltage Output

ANALOG CONTROL
145
Isolated External Voltage Control of Voltage Output
Background
Voltage control of the voltage output uses the
isolated voltage option (PSU-ISO-V). A voltage of
0~5V or 0~10V is used to control the full scale
voltage of the instrument, where:
For 0~5V: Output voltage = full scale voltage ×
(external voltage/5)
For 0~10V: Output voltage = full scale voltage ×
(external voltage/10)
Connection
When connecting the external voltage source to the
isolated voltage option, use shielded or twisted
paired wiring.
