Product Overview:
HVR620 Digital Voltage Regulator is used to adjust the field current of brushless AC synchronous generator, which can be applied to generators with the excitation system of PMG, AUXW or SHUNT. The excitation regulation mode of the regulator is automatic voltage regulation (AVR). It has USB interface and CAN BUS interface.
The product adopts 32-bit micro-processor technology, which can achieve precision measurement of multiple parameters, protection threshold adjustment, real-time data monitoring and analysis, flexible and comprehensive fault protection, etc. All parameters can be read and configured on PC via USB interface. And it features compact structure, simple connections and high reliability.
