The self-limiting temperature thermistor electric heater uses comb-shaped aluminum alloy profile as the conductive heat sink, eliminating the traditional heating material-alloy resistance wire. The internal heating core is made of PTC ceramic. The product has self-limiting temperature and constant temperature heating (when the ambient temperature, applied voltage, and heat release conditions change within a certain range, keep a certain temperature unchanged), no open flame, high heat conversion rate, minimal influence by the power supply voltage, and long natural life Such as traditional resistance wire heating elements can not match the advantages. The heater changes its own heating power with the change of external environmental conditions, that is, when the ambient temperature is low, the heat absorption is large, and the heater has good heat dissipation, its own power is large. On the contrary, it is small. Its characteristics are unique to this heater. It is a good product for drying and dehumidifying various high and low voltage switch cabinets, communication cabinets (boxes), and electrical control cabinets (boxes), preventing condensation, and improving the working environment temperature of electrical components. It is also a substitute for imported PTC heaters. (Non-standard can be customized)

Working voltage: AC/DC 220V 110V 48V 24V 12V±10% (generally 220V, voltage and power can be specified by the user)
