Automatic Voltage Regulator Brushless Generator AVR Regulator Board 140 - 220VAC 3 Phase 3A Feature:1. For excitation system: automatic voltage regulator is part of the excitation system of brushless generator, with excitation field output of 120VDC.2. 3 phase PMG: the excitation power is from 3 phase permanent magnet generator (PMG) to isolate the influence of AVR control circuit and non-linear load.3. Working Principle: Induction of voltage in the main winding of the generator and controlling the power fed to the field stator to lift the main rotor to maintain the output power.4. Good Protection: The generator voltage regulator has low speed, over-excitation and LAM protection to ensure safe operation and reliable operation.5. Compact size: automatic generator voltage regulator has small size, stable operation, less interference and wide application range. Specification: Item type: automatic voltage regulator Model: MX341 red Input power: 140-220V AC 3 phase 3A (PMG) Excitation field output: 120VDC voltage (maximum), current 2.7A (continuous), 6A in 10 seconds (discontinuous) Impedance: at least 15 Omega; Regulation rate: 1% (for brushless generator) Protection: built-in low speed, over-excitation, LAML Package list: 1 x Voltage Regulator 1 x User Manual How to use: Can be used after installation.
