Product Overview:
HVR610 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).
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. It can be widely used in all types of brushless AC synchronous generators like PMG, AUXW, SHUNT, etc. for its compact structure, simple connections and high reliability.
PERFORMANCE FEATURES
Main characteristics are as following:
- Four excitation regulation modes: automatic voltage regulation (AVR), field current regulation (FCR), power factor regulation (PF), reactive power regulation (VAR);
- Over-excitation limit, under-excitation limit, stator current limit, U/F limit function is fitted;
