The following editor of the silicone electric heating film manufacturer teaches you how to install the electric heating film? Can a DC power supply be used?
When using the silica gel electric heating film, you can choose to install it with double-sided tape, room temperature vulcanization, punching positioning and other methods according to the actual site. Silicone heating elements cannot use DC power. The heating principle of silicone heating elements is that alternating current generates a vortex magnetic field in the silicone heating element. The vortex magnetic field generates eddy currents in the silicone heating element. The resistance of the silicone heating element is large. So the eddy current Converted into heat, if direct current is used, the silicone heating sheet will not have eddy current and cannot generate heat.

2. What is the difference between 110V and 220V ptc heating film? What about mixing?
The ptc heating element is a device with positive temperature coefficient, and the resistance value increases greatly with the increase of temperature. If the 220V heating element is used on 110, its resistance increase is relatively small, and the current will be relatively large, but the heat generation will not necessarily increase a lot . It is recommended to match.
3. How to assemble 5 PTC heating elements?
The 5-head PTC heating element should be assembled according to different power requirements. 1, 3, and 5 are one pole; 2, 4 is one pole, 1, 3, and 5 are combined together as one end; 2, 4 combined together is the other end , Access to 220V is full power.
4. Will the PTC heating element explode?
There is a failure mode of PTC heating element called breakdown, and there will be blasting sound accompanied by strong light during breakdown. Under normal circumstances, the ptc heating element will have an external insulation structure, and there will be a small blasting sound when a breakdown occurs, no strong light can be seen, and it will not hurt people.
