Product Description

R449 Automatic Voltage Regulator (AVR)

The R449 AVR ensures precise voltage regulation for alternators using AREP or PMG excitation systems.

Key Features:

  • Voltage Regulation: ±0.5%
  • Short Circuit Capability: 3 × I-rated for 10 sec
  • Voltage Sensing:
    • 95-140V (110V terminals)
    • 170-260V (220V terminals)
    • 340-520V (380V terminals)
  • Response Time: 1 sec (normal), 0.3 sec (rapid)
  • Remote Voltage Adjustment: ±5%
  • Load Adjustment Module (LAM): Reduces voltage by ~15% during load impacts

Compatibility:
Standard on 8100 & 9100 series, fits LSA 51.2, 53.1, and 54 alternators.

Reliable and efficient for stable generator performance.
