Operating Principle
Power Logic's intelligent non-contact compensating AC voltage stabilizer and power supply utilize new high-speed DSP control technology, rapid AC sampling technology, RMS correction technology, zero-crossing voltage and current switching technology, and quick compensation voltage stabilization technology. They integrate intelligent instruments, fast voltage stabilization, and fault diagnosis, ensuring the product is safe, quick, and precise.
The voltage stabilizer is primarily composed of an isolation transformer, SCR silicon-controlled rectifier module, DSP control core, rapid voltage stabilization technology, and safety protection devices. It monitors the output voltage in real-time through the DSP, rapidly computes and controls the SCR module, adjusting the voltage magnitude and polarity of the primary side of the compensating transformer connected to the load, achieving the purpose of rapid voltage stabilization.
Product Features
