COMPENSATION
CURVES (See Figure 1)
1. When the frequency of the generator is lower
than the factory setting, the rated phase voltage
will decrease to protect the regulator or exciter
because of over exciter current.
2. Factory Setting
：
45 Hz
+/- 4%
ATTENTION
1. AVR can be mounted directly on the engine,
genset, switchgear, control panel, or any position
that will not affect operation. For dimension
reference, please see Figure 2.
2. All voltage readings are to be taken with an
average-reading voltmeter.
