Product Overview:
HVR410 Digital Voltage Regulator is designed for adjusting the field current of brushless AC synchronous generator, which can be applied to generators with the excitation system of AUXW and SHUNT. The regulation mode of the regulator is automatic voltage regulation (AVR). It has USB interface for operation.
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, while some parameters can be manually adjusted using the on-board potentiometer. It features compact structure, simple connections and high reliability.
