220V 4000W Compact Controller Voltage Variable Speed Portable Temperature Light Voltage Dimmer Dimmable

Product Description High-power SCR (triac) AC voltage regulator designed for smooth, stepless control of voltage, heating temperature, lamp brightness, and motor speed. Built with an FR-4 high-temperature PCB, imported thyristor chip, and full aluminum heat-dissipation fins for stable performance. Features an independent power switch for safer operation and quick power cut-off. Ideal for DIY and industrial applications where reliable AC 220V to 0–220V adjustment is needed. Key Features 4000W max (resistive load): Suitable for high-power resistive devices; for inductive loads, recommended capacity is about 1/3 of resistive. Specifications Usage Use for stepless control of many heating and lighting applications such as rice cookers, water heaters, tungsten lamps, and heating wires, as well as some small motors (observe inductive-load limits). Important: metal enclosure should be safely grounded; this unit outputs AC only. Great for workshops, DIY electronics benches, and industrial equipment where smooth voltage regulation is required.
