Caution

When using external voltage control, make sure no
more than ±11V is applied across pins 1 and 3.
Exceeding this voltage could damage the PEL-3000.
Exceeding 11.8V will cause an EXT.OV alarm
message to appear which also will reset the voltage
output to 0V until the external voltage is reduced
back down below 11.8V.

Use caution when using pin 3. Pin 3 is directly
coupled to the negative input terminal.

Description

External voltage control can be used to control
the current, voltage, resistance and power for
CC, CR, CV and CP modes. Configuration for
each operating mode is the same.
