PTC heater uses thermistor as the main heating material, and uses the characteristics of PTC resistance to change with temperature to stop temperature or power control, so that the PTC heater can be better guaranteed under the condition of environmental temperature or voltage changes Relatively stable heating temperature or heating power.
1. High flexibility, the temperature coefficient of resistance is 10-100 times larger than that of metal;
2. Wide operating temperature range, room temperature devices are suitable for -55℃～315℃;
3. Easy to use, the resistance value can be chosen arbitrarily between 0.1～100kΩ;
4. Good stability and strong overload ability.
1. The PTC heating device has the characteristics of automatic constant temperature, no temperature control system is required, and the PTC heating element can be directly energized.
2. When the PTC heater is used to heat liquid (such as water), the PTC heating element will not be damaged after the liquid is dried.
3. If the PTC heater is used to heat the cold air, the PTC heating element will not be damaged when the air is not supplied.
4. There are four kinds of electrodes for customers to choose: printed aluminum, printed aluminum + silver, melt-blown metal aluminum, electroless nickel + silver.
5. Long service life, under normal environment, the service life can reach more than 10 years.
6. Reliable work, using the internal characteristics of the PTC heater to control the temperature, and never over-temperature.
7. The working voltage is very wide. When the operating voltage changes twice, the change in surface temperature is very small.
8. This type of product does not have wires and insulation layers. Customers also choose products with wires and insulation layers, or products with shells.
9. When multiple PTC heaters are used together, they should be connected in parallel, not in series.
10. Different heat dissipation conditions make the heating power of PTC heaters vary greatly.
