Working Principle

This intelligent non-contact compensating AC voltage stabilizer adopts high-speed DSP arithmetic chip control technology, fast AC sampling technology, RMS correction technology, voltage and current zero-crossing switching technology and fast compensation voltage stabilization technology. Combined with fault diagnosis, the product is safe, efficient and precise.

The voltage stabilizer is mainly composed of isolation transformer, SCR thyristor module, DSP control core, fast voltage stabilization technology and safety protection device. Through DSP, the output voltage is monitored in real time, and the SCR thyristor module is quickly calculated and controlled to adjust the voltage connected in series at the load end. Compensate the voltage size and polarity of the primary side of the transformer to achieve the purpose of fast voltage regulation.

Features
