Precautions for PTC heating elements for electric vehicles
1. After the liquid is dried, the PTC heater will not be damaged.
2. If the PTC heating plate is used to heat the cool air, the PTC heating plate will not be damaged when the air is not supplied.
3. The service life is long, and the service life can reach more than 10 years when used in a normal environment.
4. Reliable operation, using the internal characteristics of the PTC heater to control the temperature, and will never over-temperature.
5. The operating voltage is very wide: when the operating voltage is changed twice, the change in surface temperature is very small.
6. When multiple PTC heaters are used together, they should be connected in parallel, not in series.
7. Different heat dissipation conditions make the heating power of PTC heaters vary greatly.
8. The heating power increases from large to small after power-on, and finally stabilizes. The stable power is related to the operating conditions. If the operating conditions of the same PTC heater are different, the power may differ several times. The faster the heat dissipation, the more stable power; the higher the surface temperature of the PTC, the higher the power.
9. The surface temperature of the PTC heating element is controlled by the PTC itself, and it can also be controlled by disconnecting the circuit, but it cannot be controlled by the regulated voltage.
10. PTC itself is highly reliable and has a long lifespan. However, if the device is improper, the product will show unstable power and temperature.
11. When multiple PTCs are used together, they should be connected in parallel, not in series.
