4000W 220V AC SCR Voltage Regulator Motor Speed Controller

Control AC power for compatible electrical loads with this 4000W AC SCR Voltage Regulator. Designed for adjustable AC voltage control, this module uses an SCR/thyristor-based control circuit and a rotary adjustment knob.

It is primarily intended for resistive loads such as compatible heating elements and incandescent lamps. It may also be suitable for certain single-phase AC motors, but motor compatibility must be checked before use.

Key Features

• 220V AC operation: Designed for a 220V AC supply.

• 4000W advertised maximum: Maximum rating specified for resistive loads; this is not a guarantee of continuous operation at 4000W.

• Adjustable AC output: Allows adjustment of the AC power delivered to a compatible load.

• Rotary adjustment: Convenient manual control using the adjustment knob.

• SCR control technology: Uses thyristor-based AC power regulation.

• Multiple applications: Suitable for compatible heating and lighting applications.

Technical Specifications

Suitable Applications

• Compatible electric heating elements

• Resistive heating wires

• Incandescent lamps

• Suitable workshop power-control applications

• Certain compatible single-phase AC motors, subject to motor specifications

Important Compatibility Information

This controller is primarily intended for resistive loads. Do not assume compatibility with induction motors, brushless motors, non-dimmable LED lamps, CFL lamps, or electronic appliances. Motor speed control depends on the motor design and its compatibility with phase-controlled AC power.

Electrical Safety

• The controller operates at hazardous mains voltage.

• Installation should be performed by a qualified electrician.

• Disconnect the mains supply before installation or servicing.

• Use an appropriately rated enclosure, wiring, terminals, and protective devices.

• Provide suitable heat dissipation and ventilation.

• Do not treat the advertised 4000W maximum as a continuous-use rating.

• Never exceed the verified current and power limits of the exact module.
