Voltage Regulator for Three-Phase Synchronous Generators "M40FA610A"

The M40FA610A analog voltage regulator is used in generators/alternators produced by Marelli Motori of the M8B and MJB series, size range 160-500 with power system from regulator to the power winding of the generator or from an external power winding. The regulator is completely isolated to maintain high operating reliability even in difficult environmental conditions (high levels of humidity, dust, saline atmosphere), and in the presence of vibrations. The regulator is suitable for operation on both three-phase generators and single-phase generators from 10 to 2000KVA.

Technical specifications:

  • Supply voltage (±10% of range tolerance, 50/60Hz) 170÷277 V
  • Voltage sensing (single phase) (±10% of range tolerance, 50/60Hz) 170÷277 V
  • Maximum continuous field current 8 A
  • Maximum forcing field current (1 minute) 15 A
  • Maximum field voltage 100 V
  • Field resistance 3 W ÷ 25 W
  • Regulation accuracy (steady state conditions, rated load, balanced and non-deformable, constant frequency) ±1 %
  • Thermal drift (% of voltage change per 50°C change from Tamb, after 10 minutes) ±0.5%
  • Response time 1 cycle
  • Operating temperature -20°C / +60°C
  • Weight 460 g
