EXTERNAL CONTROL

External Voltage Control - Overview
Background External voltage control of the CC, CR, CV and
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.

The input impedance for external voltage control is
10kΩ.
Use a stable voltage supply for the external voltage
control.
