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.
