The wiring method of PTC heating sheet How to connect a total of two terminal posts, pro: according to different power needs to be assembled, 1, 3, 5 is a pole, and together as one end; 2, 4 is one pole, and together for the other end, access to 220V is full power. PTC heating element, also known as PTC heater, is composed of PTC ceramic heating element and aluminum tube. This type of PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant temperature and power-saving electric heater. The outstanding feature lies in the safety performance, and in any application, the surface "redness" phenomenon of electric heating tube heaters will not occur, resulting in scalds, fires and other safety hazards.
