EA45C is a Parallel Module. The Droop and Trim must be adjusted when in used for parallel operation, factory
preset is counterclockwise to the end.
DROOP
ː Adjust the quadrature droop ratio of C1, C2 current compensation input value to generator output voltage.
When CT and AVR sense that the output voltage and current of the generator are out of sync (leading or lagging),
the AVR will increase (lead) or decrease (lag) the generator voltage. Droop was used to adjust the influence ratio of
CT input current to the generator voltage. Turn counterclockwise to the end is 0%, and clockwise to the end is +/-7%
(Max.).
TRIM
:
Adjust the influence ratio of the analog voltage input value of A1 and A2 to the generator voltage. When the
system provides DC voltage to terminals A1 and A2, the higher the DC voltage, the higher the generator voltage,
and vice versa. The TRIM knob is used to adjust the influence ratio of the DC input voltage to the generator voltage,
the counterclockwise to the end is 0, and clockwise to the end is +/-10% (Max.).
ATTENTION
※
The A1 and A2 signal must be isolated from the power.
