Key Features
- 4000W / 18A capacity: Handles heavy resistive and motor loads including industrial heaters, large incandescent arrays, and power tools.
- Smooth 0-220V adjustment: Phase-angle SCR control delivers stepless voltage regulation via a simple rotary knob - no complex wiring needed.
- Compact & lightweight: Tiny PCB footprint fits easily inside enclosures, control panels, or DIY project boxes.
- Aluminium heatsink pre-installed: Efficient thermal management out of the box; add a cooling fan for sustained loads above 2000W.
- Screw terminal connections: Secure, tool-friendly wiring - no soldering required for installation.
- Multi-purpose control: Functions as a motor speed controller, light dimmer, heater thermostat, or general-purpose AC voltage regulator.
- Wide compatibility: Works with 220V-240V AC mains supply common across India and most countries.
Why Choose This SCR Regulator?
- 100% authentic module sourced from trusted, authorized component suppliers.
- 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse to most Indian pin codes; same-day delivery within Bengaluru.
- Expert technical support included - get wiring guidance, load calculations, and troubleshooting help from real engineers.
- Proven reliability: Thousands of units deployed in hobbyist, educational, and industrial settings.
- Exceptional value: Industrial-grade power control at a fraction of the cost of commercial dimmers and VFDs for resistive loads.
How It Works
The module uses SCR phase-angle control - a well-established technique where the thyristor switches on at a variable point in each AC half-cycle. Turning the potentiometer clockwise increases the conduction angle, delivering more voltage (and therefore more power) to the load. Turning it counter-clockwise reduces voltage smoothly down toward zero. This method is highly efficient because the SCR dissipates very little power itself, keeping the module cool even at high loads.
Project Ideas & Applications
- Motor Speed Control: Regulate the speed of AC universal motors in power tools (drills, grinders, routers) and small appliances. Ideal for workshop setups where variable speed improves precision.
- Light Dimming: Dim incandescent bulbs and halogen lamps for stage lighting, photography studios, or ambient home lighting. (Note: Not recommended for LED or CFL bulbs without compatible drivers.)
- Heater & Temperature Control: Adjust power to electric heaters, soldering irons, hot-air stations, heat guns, or kiln elements for precise thermal management.
- Soldering Station Upgrade: Pair with a standard soldering iron to create a budget temperature-controlled soldering setup for electronics
