The D350 Leroy Somer digital automatic voltage regulator AVR for industrial alternators provides excitation current up to 5 A with excellent reliability for permanent magnet (PMG) or AREP (auxiliary winding) excitation types.

Leroy Somer AVR D350 includes advanced protections such as over-excitation limitation and voltage sensing loss. It also includes speed detection capabilities, with over- and under-speed alarms. Leroy Somer D350 Voltage Regulator also features voltage droop for genset parallel operation, and it is equipped with a Load Acceptance Module (LAM) to handle load impact events.
