New energy vehicle heater electric vehicle PTC heating element precautions


1. After the liquid is dried, the PTC heating plate will not be damaged.

2. If the PTC heating plate is used to heat cool air, the PTC heating plate will not be damaged without air supply.

3. The service life is long. Under normal conditions, the service life can reach more than 10 years.

4. The operation is reliable, and the internal characteristics of PTC heating plate are used to control the temperature, so that the temperature will not exceed the temperature for a long time.

5. The operating voltage is very wide: when the operating voltage changes twice, the change of surface temperature is very small.

6. When multiple PTC heating plates are used together, they should be connected in parallel rather than in series.

7. Different heat dissipation conditions make the heating power of PTC heating plate very different.

8. The heating power changes from high to low after power on until it is stable. The stable power is related to the application conditions. If the application conditions of the same PTC heater are different, the power may differ by several times. The faster the heat dissipation, the greater the stable power; The higher the surface temperature of PTC, the higher the power.

9. The surface temperature of PTC heating parts is controlled by PTC itself and can also be controlled by disconnecting the circuit, but it cannot be controlled by regulating voltage.

10. PTC has high reliability and long service life, but if it is not installed properly, the goods will show unstable power and temperature.

11. When multiple PTCs are used together, they should be connected in parallel rather than in series.
