Good performance This voltage regulator includes a wave voltage absorption circuit that effectively protects the large-power silicon controlled rectifier and helps ensure longer service life and durability. Wide adjustable range Output voltage is adjustable from 50V to 220V, allowing easy matching to different loads and applications. Wide application Can be used as a heat controller on electric stoves and water heaters; a lamp dimmer for lighting; a speed controller for small motors; or a temperature controller for an electric soldering iron. Functional scope Supports dimming, temperature, voltage and speed control for compatible devices and loads. Use scenarios - Dim lamps to set the desired ambience by adjusting output voltage. - Regulate heating temperature for electric stoves, water heaters, or soldering irons. - Control the speed of small motors or fans in hobby or light industrial projects.
