External Resistance Control - Overview
Background External resistance control of the CC, CR, CV
and CP modes is accomplished using the J1
connector on the rear panel.
A resistance of 0kΩ~10kΩ is used to control the
input current, voltage, resistance or power on
the PEL-3000.
The input can be configured to vary in
proportion to the external resistance or the
inverse. See page 140 for more details on
proportional and inverse resistance control.
Note
Exceeding 11.8k Ω will cause an EXT.OV alarm
message which will reset the voltage output to 0
until the external resistance is reduced back down
below 11.8k
Ω.
