Voltage Bias input from EGCP-2
Internal Trim adjustment potentiometer
sets effective range of +/- 1 VDC bias
from EGCP-1 control. Usually a +/- 10%
voltage change for the +/-1VDC input
is more than sufficient for good VAR
and PF control.

.
On regulators without a trim input
such as Leroy Summers AVRs,
an external trim pot must be used
to limit the range of the voltage
bias input from the EGCP-2 control.

AVR DROOP
• It is highly recommended to fit the AVR with a Droop CT input, and utilize
a medium droop level on the AVR. This adds stability to the AVR for
VAR/PF sharing at low loads.
• Cross current compensation should be disabled in the AVR Droop CT
circuit.
