Voltage Regulator for Three-Phase Synchronous Generators "M40FA640A MARK I"

Item Description:

Voltage regulator M40FA640A type "MARK I" is suitable for MARELLI MOTORI synchronous generators, MJB series, size range 160-500. This regulator is suitable for operating on machines from 10 to 2000 kVA. The regulator is fully isolated to maintain high reliability even in harsh environmental conditions (high humidity, dust, salt atmosphere) and high vibration level. The regulator is suitable for both single-phase and three-phase operation.

  • ISOLATED AND SAFE: The entire regulator is isolated and safer to use in harsh environments and high vibration levels.
  • HIGH QUALITY MATERIALS: The product uses high quality electronic components to maintain high reliability in harsh environmental conditions (high humidity, dust, salt environment).
  • SUITABLE FOR: This regulator is suitable for single-phase and three-phase generators.
  • HIGH REGULATION ACCURACY: Theoretical fluctuation is only 0.5%.
  • MORE DURABLE: The regulator board is made of flame retardant and high temperature resistant material, which makes it safe and durable.
