High reliability and protection - This voltage regulator uses a wave voltage absorption circuit to protect large power silicon controlled rectifiers, improving durability and extending service life. Wide adjustable range - Output voltage can be easily set from 50V to 220V for flexible use. Broad compatibility and applications - Can be used as a heat controller on electric stoves and water heaters. - Serves as a lamp dimmer for lighting control. - Functions as a speed controller for small motors. - Acts as a temperature controller for electric soldering irons. - Enables dimming, temperature control, voltage adjustment, and speed control. 2-3 practical use scenarios - Dim lighting: adjust lamp brightness to the desired level in home or workshop settings. - Temperature/heat control: regulate heating elements on stoves or water heaters for energy efficiency and precise output. - Motor and tool control: manage small motor speeds or maintain soldering iron temperature for DIY projects and repairs.
