The D350 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.
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. D350 also features voltage droop for Genset parallel operation, and it is equipped with a Load Acceptance Module (LAM) to handle load impact events.
