Leroy-Somer D350 Digital Automatic Voltage Regulator

The Nidec Leroy-Somer D350 digital automatic voltage regulator (AVR) is designed for brushless synchronous generator sets for marine and industrial applications. It monitors generator voltage and CT current signals continuously to adjust excitation current and maintain stable output voltage. Equipped with built-in NF Link wireless communication, RTD temperature input and multi-channel digital I/O, it provides full protection against overcurrent, overheating and underfrequency faults. It supports remote parameter configuration and real-time operation data monitoring for onboard power plants and standby power systems.
