Reliable Voltage Regulation AVR SX440 Voltage Regulator For NEWAGE Generator
DESCRIPTION


Features:
brand new high quality
Made of high quality material,
The SX440 is a two-phase inductive automatic voltage regulator (AVR) that forms part of a brushless generator excitation system.
The AVR senses the voltage in the generator main winding and controls the feed to the exciter stator and main rotor to maintain the generator output voltage within a specified range to compensate for generator load, temperature and power factor.
Field power comes from a three-phase permanent magnet generator (PMG), which isolates the AVR control circuit from the effects of non-linear loads and reduces RFI to the generator terminals. Continuous generator short circuit current is another characteristic of permanent magnet generator system generators.
The AVR is easy to drop CT connections and can run in parallel with other generators of similar equipment.
