SmartGen HVR1000 Digital Voltage Regulator

Product Overview:

HVR1000 Digital Voltage Regulator is used to adjust the field current of brushless AC synchronous generator. It has four excitation regulation modes: automatic voltage regulation (AVR), field current regulation (FCR), reactive power regulation (VAR), power factor regulation (PF). It adopts CAN BUS interface and follows SAE J1939-75 protocol.

The product uses 32-bit micro-processor technique which can achieve precision measurement, protection threshold adjusting, real-time data monitoring and analysis, flexible and comprehensive fault protection, etc. All parameters can be read and configured through USB interface via PC or Bluetooth via mobile APP. It can be widely used in all types of brushless AC synchronous generators like PMG, AREP, SHUNT, etc. for its compact structure, simple connections and high reliability.
