R630

Automatic Voltage Regulator for LSA alternators

R630

The R630 automatic voltage regulator (AVR) for the LSA series of alternators provides excitation current up to 15 A with excellent reliability for SHUNT, AREP & PMG excitation types. 

The R630 supports 3-phase sensing as a standard and can be equipped with optional modules to allow follower manual mode, and Cos Phi & kVAR regulation modes.
