AVC63-12 and AVC125-10
Voltage Regulator
INTRODUCTION
The AVC63-12 and AVC125-10 regulate the level of excitation supplied to the field of a conventional, brushless,
synchronous generator.
Regulation is achieved by sensing the generator output voltage, converting it to a dc signal, and comparing the
signal to a reference voltage. An error signal is developed and used to control the dc field power in order to
maintain a constant generator output.
Each regulator includes frequency compensation with selectable slope, inverse-time overexcitation shutdown,
buildup circuitry, single-phase or three-phase voltage sensing, single-phase or three-phase shunt or permanent
magnet generator (PMG) power input, parallel droop compensation, and an accessory input. The accessory input
provides compatibility with devices such as var/power factor controllers or excitation limiters.

Voltage Buildup
Automatic voltage buildup occurs from residual generator voltage as low as 6 Vac (AVC63-12) or 12 Vac
(AVC125-10).
Overexcitation Shutdown
Overexcitation shutdown protection reduces the output voltage to zero in the times shown below for the listed
voltages. Other voltages and times are based on the inverse time characteristic curves of Figures 4 and 5

MOUNTING
Regulators are contained in an encapsulated plastic case and may be mounted in any convenient position. A
regulator may be mounted directly on a genset using UNC ¼-20 or equivalent hardware. Hardware selection
should be based on any expected shipping/transportation and operating conditions. The torque applied to the
mounting hardware should not exceed 65 in-lb (7.34 Nm). See Figure 6 for regulator dimensions.
