  • Controls motor speed via PWM and SCR circuitry
  • Handles loads up to 4000 W for heavy equipment
  • Designed as internal power cable for direct installation

220 V 4000 W AC voltage regulator

This internal power cable integrates an AC voltage regulator rated for 220 V and 4000 W. It uses PWM control with an SCR circuit to function as a motor speed controller, dimmer or rectifier. The unit is designed for builders who need adjustable AC power delivery inside a custom enclosure.

Check your mains voltage and load before ordering

Verify that your supply is 220 V AC and that the connected equipment does not exceed 4000 W. Ensure the enclosure has space for the regulator and that wiring follows the PWM control scheme. This part is not suitable for DC-only systems or loads requiring a different input voltage.
