SBW Three Phase high-Power Compensated Voltage Stabilizer

Short Description:

The product is by the pillar of contact type self-coupling voltage regulator, automatic sampling, protection, control circuit, low speed synchronous motor, grouped into compensation transformer and other main part, when the mains voltage instability or user load changes caused by the fluctuation, the voltage signal sampling circuit treated synchronous motor, make it move up and down the contact voltage regulator for carbon brush with dynamic column, guarantee the stability of output voltage,  It has the advantages of large capacity, low loss, high efficiency, wide voltage range, high precision, strong protection function, reliable operation and so on. And with phase loss, over voltage, under voltage and over current protection.

Product Detail

Product Tags


  • SBW mainly consists of pillar contact type voltage regulator, sampling protection circuit,low-speed synchronous machine and compensation transformer.
  • Sampling circuit transfer signal to synchronous machine,then synchronous machine guide the brush regulating,assure steading the output waveform.
  • Large capacity,high effective,small consumption,same waveform,steady&reliable output voltage and overvoltage/overcurrent protection.
