Wholesale Price MDG Series Single Phase Brushless Synchronous A.C Alternator

MDG BRUSHLESS SYNCHRONOUS A.C ALTERNATORS

EXCITATION SYSTEM SX440(460)

The main stator provides power for excitation of excitor field by Automatic voltage regulator.The efficient semi-conductors of Automatic voltage regulator ensure that the output voltage grows guadually from lower residual voltage to rated voltage.Over excitation voltage protection is prevented continually over voltage caused by alternator faulty.

The standard sensor is 2 phase sensing and supply the stable voltage regulation rate.The output power of excitor rotor is supported to the main stator through 3-phase full wave rectifier.The rectifier has surge resistance and avoids the impact caused by short circuit or parallel synchronzation loss.
