Vszerda 4000W Thyristor Voltage Regulator 220V

SKU CH-Q0QT-VQS58

A 4000W thyristor voltage regulator for 220V AC circuits with an integrated case

  • High power handling up to 4000W for demanding electrical loads
  • Thyristor-based regulation provides precise AC voltage control
  • 220V AC input compatibility suits standard mains supply
  • Protective case included for safe and durable installation

4000 W thyristor regulator for 220 V mains

This 4000 W thyristor voltage regulator controls AC 220 V loads up to its rated power. It is built for hobbyists and technicians who need adjustable voltage for heaters, lamps or motor speed tests. The enclosed case version suits bench use where exposed terminals would be a hazard.

Thermals noise and power draw

The thyristor switching element runs warm under continuous high-current loads, so keep ventilation space around the case. No fan is fitted, making operation silent apart from a faint coil hum at partial settings. Power consumption is essentially the load itself plus minimal controller overhead.

Questions about this item

How is the Vszerda 4000W Thyristor Voltage Regulator installed, and what wiring step do people often get wrong?

Connect the AC 220V supply to the input terminals and the load to the output terminals, ensuring the live and neutral wires are not reversed; a reversed connection will prevent the thyristor from regulating voltage correctly.

What maintenance or replacement will the Vszerda 4000W Thyristor Voltage Regulator need over time?

Periodically check the terminal screws for tightness and inspect the case vents for dust buildup; the internal thyristor is solid-state and has no user-serviceable parts, so replacement is only required if the unit fails to regulate the 4000W load.
