General description
MX341 is a two phase sensed Automatic Voltage
Regulator and forms part of the excitation system for a
brush-less generator. Excitation power is derived from a
three-phase permanent magnet generator (PMG), to
isolate the AVR control circuits from the effects of nonlinear loads and to reduce radio frequency interference on
the generator terminals. Sustained generator short circuit
current is another feature of the PMG system.
The AVR senses the voltage in the main generator
winding and controls the power fed to the exciter stator
and hence the main rotor to maintain the generator output
voltage within the specified limits, compensating for load,
speed, temperature and power factor of the generator.
Soft start circuitry is included to provide a smooth
controlled build up of generator output voltage.
A frequency measuring circuit continually monitors the
shaft speed of the generator and provides under-speed
protection of the excitation system by reducing the
generator output voltage proportionally with speed below
a pre-settable threshold. A further enhancement of this
feature is an adjustable volts per Hertz slope to improve
engine recovery time on turbo charged engines. Soft start
circuitry is included to provide a smooth controlled build
up of generator output voltage.
Uncontrolled excitation is limited to a safe period by
internal shutdown of the AVR output device. This
condition remains latched until the generator has
stopped.
Provision is made for the connection of a remote voltage
trimmer, allowing the user fine control of the generator’s
output.
An analogue input is provided allowing connection to a
Newage Power Factor controller or other external devices
with compatible output.
The AVR has the facility for droop CT connection, to allow
parallel running with other similarly equipped generators.
