Same as the Dimmer D350 but in a different design to fit constructions that the D350 may not make Suitable for dimmer lighting, electrical resistors, MOTOR speed adjustment for fireplaces, etc. This dimmer can be used to adjust the motor speed of an electric drill, a vacuum cleaner and generally a motor with coals. Also suitable for Adjusting LED lamps, as long as they have this feature (Dimmable). To achieve maximum power the Triack needs a heatsink. By changing the Triack we can have power up to 2KW. Easy to build (assemble) even for those who have little knowledge of electronics.
