1WIDE APPLICATION: The voltage regulator is widely used for electric furnace, incandescent lamp, baking lamp, PTC heating plate, electric soldering iron, etc. Most motors with one capacitor can be used. 2SAFE TO USE: The speed regulator with fuse and housing is safer and more convenient to install, and is more suitable for families and factories and enterprises that are not convenient to install. 3LARGE CURRENT SAFE: 41A silicon controlled rectifier and high temperature resistant circuit board are used. The circuit design of motor voltage regulator is reasonable, and the thickened welding circuit design is adopted. Even if the high current passes,the regulator is enough to deal with it, and the use is safer and more reliable. 4RUST RESISTANT: 1.5 thick aluminum plate and stainless steel are used for external molding, which is beautiful, safe, convenient, and rust resistant, ensures a long life span. 5IDEAL REPLACEMENT: This voltage regulator is an ideal replacement for the old and damaged parts for better regulating performance.
