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
-
Stepless AC control: Adjust output from 0–220V AC to fine-tune speed/heat/light without frequent on-off cycling.
-
4000W max (resistive load): Suitable for high-power resistive devices; for inductive loads, recommended capacity is about 1/3 of resistive.
-
Efficient cooling & durable build: Aluminum housing with conductive aluminum fins supports heat dissipation for steadier operation.
-
Upgraded electronics: FR-4 heat-resistant circuit board, precision high-voltage resistors, and high-voltage capacitors for stable regulation.
-
Protection & stability: Peak voltage absorption circuit and multiple protections help safeguard the SCR during operation.
-
Practical installation: Compact body with mounting holes; portable for workshop benches, equipment panels, and DIY test setups.

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.
