1,Three Phase Induction: Our automatic voltage regulator is a three phase induction automatic voltage regulator that is part of the brushless generator excitation system. 2,Interference Reduction: The automatic voltage regulator isolates the control circuit from the effects of non linear loads as appropriate and reduces RF interference at the generator terminals. 3,Protection Functions: This automatic voltage regulator also has protection functions, built in low speed protection, over excitation protection and LAM protection. 4,Control Power: The automatic voltage regulator senses the voltage of the generator main winding and controls the power fed to the exciter stator and the main rotor voltage to keep the generator output voltage within the specified range. 5,Easy Installation: Our automatic voltage regulator is very easy to install and can be used for a long time under normal operation and use. Item Type: Automatic Generator Voltage Regulator Model: MX341 Material: ABS Impedance: Minimum 15Ω Adjustment Rate: 1% Application: For brushless generators Protection Function: Built in low speed, over excitation, LAM 1 x Automatic Voltage Regulator 1 x Instruction Manual Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
