External Voltage Control - Overview
Background
External voltage control of the CC, CR, CV, CP and
Cx+CP mode is accomplished using the J1
connector on the rear panel. An input voltage of 0-
10V corresponds to 0% - 100% of the rated current
(CC mode), rated voltage (CV mode), or rated
power (CP mode). For CR mode, 0V - 10V
corresponds to the maximum resistance -
minimum resistance.
Connection
When connecting the external voltage source to the
J1 connector, use a ferrite core and use twisted pair
wiring.
