Precision Power Control for Every Project
Whether you are building a custom workstation, repairing an industrial tool, or fine-tuning home appliances, having stable power delivery is non-negotiable. The 2000W AC SCR Voltage Regulator is designed to give you absolute control over alternating current devices, turning complex power management into a simple twist of a dial.
Heavy-Duty Performance You Can Trust
We know that component reliability is critical for engineering and DIY applications. This speed controller is built around an original imported STMicroelectronics high-power bidirectional SCR, capable of withstanding high voltages up to 1200V.
Supported by high-voltage capacitors and precision multi-turn potentiometers, it safely handles a maximum current of 25A. This robust architecture effectively solves the overcurrent problems often caused by the low resistance of cooling heating wires, protecting both the module and your valuable equipment.
Plug-and-Play Simplicity
Forget about complicated wiring diagrams or the need to solder extra components. This voltage regulator features integrated screw terminals and a pre-installed variable resistor knob with a secured nut. Simply connect your AC input (110V-220V) to the "IN" terminals, and your appliance to the "OUT" terminals. Within minutes, you can dial in the exact output voltage between 50V and 220V to achieve the perfect lighting mood, motor speed, or soldering iron temperature.
Built for Versatility
This isn't just a dimmer switch; it is a multi-purpose control hub. Its compact footprint (54 x 48 x 29mm) allows it to be easily integrated into custom enclosures, making it a staple for any serious electronics workbench or professional repair kit.

FAQ Section
FAQ Section
Q: Can I use this 2000W regulator to run a 2000W AC motor?
A: For resistive loads (like heating elements or incandescent bulbs), it can handle close to the 2000W peak. However, for inductive or capacitive loads like motors or water pumps, we strongly recommend keeping the maximum power under 1000W to accommodate startup surges and ensure the longevity of the controller.
Q: Does this work with LED lights?
A: This SCR dimmer is primarily designed for resistive loads like traditional incandescent or halogen bulbs. It is generally not recommended for standard LED lights or energy-saving lamps unless those specific bulbs are explicitly labeled as "dimmable" using leading-edge TRIAC/SCR dimmers.
Q: Do I need an external heat sink for continuous use?
A: The module comes with a built-in aluminum heat sink that is sufficient for intermittent use or lower wattage applications. If you plan to run it near its maximum capacity (e.g., above 1000W) for extended periods, adding a cooling fan or a larger heat sink is a good engineering practice to maintain optimal temperatures.
