About this product
An SCR (thyristor) phase-angle dimmer module rated for 5000 W on 220 VAC mains. It varies the power delivered to resistive AC loads such as incandescent lamps and heaters by controlling the firing angle. Mains voltage is dangerous, so install it inside an insulated enclosure and only with proper mains-wiring knowledge.

Frequently asked questions
Does the 5000 W rating mean I can run any 5 kW load?
No. The rating is the maximum for a suitable resistive load. Inductive loads, motors and LED drivers behave differently under phase-angle dimming, so match the load type to the dimmer before connecting.
Do I need a fuse or protection?
Yes. Install a fuse or circuit breaker rated for the load current on the mains line, and use a heatsink-compatible enclosure, since SCR dimmers dissipate heat at high power.
