Three-phase High-precision Fully Automatic AC Voltage Regulator

  • Browse number: ...
  • Release time: 2026-10-21
TND single-phase and SJW three-phase series voltage regulators are designed by our company for stabilizing AC voltage by introducing and absorbing advanced Western European technologies and combining with China's national conditions. When the voltage of the external power supply network fluctuates due to voltage variation or load change, they can automatically keep the output voltage stable.

Product Introduction

TND single-phase and SJW three-phase series voltage regulators are designed by our company for stabilizing AC voltage by introducing and absorbing advanced Western European technologies and combining with China's national conditions. When the voltage of the external power supply network fluctuates due to voltage variation or load change, they can automatically keep the output voltage stable. Compared with other types of voltage regulators, this series of products features large capacity, high efficiency, no waveform distortion, balanced voltage regulation, wide applicable loads, capability to withstand instantaneous overload, long-term continuous operation, digital display function, and protection functions including overvoltage protection, undervoltage protection, automatic recovery after power resumption and fault alarm.
