220V 2000W Voltage Regulator — Precise control over speed, light, and heat with a single turn
Is your motor running too fast? Is your lamp too bright? Do you need to fine-tune a heating element? These are common challenges in the workshop or around the home, and this 220V voltage regulator solves them all without the need for complex wiring modifications.
Note: Exclusively compatible with resistive loads and AC universal/inductive motors. Not suitable for LED bulbs, energy-saving (CFL) bulbs, or DC motors.
Why choose this model? (Key Advantages):
- Continuous 50V–250V adjustment — the rotary potentiometer provides smooth, fine control rather than abrupt steps, ensuring gradual speed increases and dimming.
- Supports up to 2000W — whether it’s a water pump, industrial fan, electric oven, or heating element, you can control them all with one module.
- 4-wire connection — 2 input wires from the mains and 2 output wires to the load. Ready to use in minutes, no professional electrician required.
- Compact 4.8×5.5×2.7 cm design — fits easily into any DIY enclosure or electrical panel without taking up valuable space.
- Integrated aluminium heatsink — provides efficient passive cooling for loads up to 1700W; for heavier loads, simply add a small fan to ensure years of reliable service.
Performance and Technical Details
At the heart of this module is a high-power TRIAC that regulates voltage using phase-cutting technology. By precisely clipping each half-cycle of the AC current, it delivers a smooth and stable power output to your device. The result: motor speed increases or decreases without jumping, and incandescent bulbs remain flicker-free. For loads exceeding 1700W, the integrated heatsink benefits from additional airflow—a small fan directed at the module is sufficient to keep temperatures within safe limits and extend the lifespan of the components.

Installation and Usage Instructions
- Connect the Phase (L) and Neutral (N) wires from your 220V mains to the input terminals of the module.
- Connect the two output wires to the device you wish to control—such as a motor, fan, incandescent bulb, or heating element.
- Ensure the rated power of your load does not exceed 2000W before powering the circuit.
- Rotate the adjustment potentiometer gradually to set the desired voltage, speed, or intensity.
- For loads exceeding 1700W, mount a cooling fan directed towards the metal heatsink.
- Always install the module in a fire-resistant enclosure, away from direct contact with combustible materials.

Frequently Asked Questions
Can I use this dimmer for LED or energy-saving bulbs?
No. It is designed only for incandescent filament bulbs and halogen lamps. LED and CFL bulbs require specialised dimmers; using them with this module may cause damage.
Does it work with any type of electric motor?
It is compatible only with universal (brushed) motors and certain single-phase inductive motors. It is not compatible with DC motors or inverter-driven motors. Please verify your motor type before connecting.
Is a cooling fan strictly necessary?
For loads under 1700W, the integrated heatsink is sufficient. If you are operating loads between 1700W and 2000W, or using the device for extended periods, a cooling fan is highly recommended to prevent overheating.
How do I verify the module is connected correctly?
After connecting, rotate the potentiometer; you should immediately observe a progressive change in speed, light, or temperature. If the equipment does not respond at the minimum setting, increase the level gradually until the load activates.
Can I use this to control a ceiling fan?
Yes, provided the fan uses a universal or single-phase inductive motor and the power rating does not exceed 2000W. The fine adjustment of the potentiometer allows for precise speed control.

Simple, cheap, and effective. I used it to dim a high-powered shop light and it works perfectly without any buzzing.
