The principle is that the PTC heating plate is heated from heat after powering up, and the resistance value rises into the transition zone, and the surface temperature of the PTC heating plate will remain constant, which is only related to the Curie temperature and applied voltage of the PTC heating sheet, and basically has nothing to do with the ambient temperature. Even in the case of non-normal operation, the input power can be reduced very low due to the regulation of the PTC element itself, and there will be no surprises.
Function:
1. Constant temperature heating PTC thermistor has constant temperature heating characteristics, the principle is that PTC thermistor is heated up from heat after powering up, so that the resistance value enters the transition zone, and the surface temperature of constant temperature heating PTC thermistor will remain constant, the temperature is only related to the Curie temperature and applied voltage of the PTC thermistor, and basically unrelated to the ambient temperature.
2. PTC heating element is a heating element designed by using constant temperature heating PTC thermistor and constant temperature heating characteristics. In small and medium-power heating occasions, PTC heating elements have the advantages of constant temperature heating, no open flame, high thermal conversion rate, minimal influence by power supply voltage, long natural life and other advantages that traditional heating elements cannot match, and their application in electric heating appliances is increasingly favored by R&D engineers.
3. Constant temperature heating PTC thermistor can be made into a variety of shape structure and different specifications, common are round shape, rectangle, long strip, ring and honeycomb porous. The combination of the above PTC heating elements and metal components can form various forms of high-power PTC heating elements.
