What will happen if the surface temperature of PTC is high?


The higher the surface temperature of the PTC, the higher the power. When using the PTC electric heater, pay attention that the PTC heating element has the characteristics of automatic constant temperature, and it does not need a temperature control system, just power on the PTC heating element directly. When the PTC heating element is used to heat liquid such as water, the heating element will not be damaged after the liquid is dried. If the PTC heating element is used to heat cold air without supplying air, the PTC heating element will not be damaged.

The PTC heater has a long life span and can be used under normal conditions for more than 10 years.

It works reliably, and uses the internal characteristics of the PTC heating element to control the temperature, never exceeding the temperature.The working voltage is not constant: when the working voltage changes twice, the surface temperature changes a little.

When multiple PTC heating panels are used together, they should be connected in parallel, not in series. Different heat dissipation conditions make the heating power of the PTC heater vary greatly. The heating power is stable from high to low after power on. The stable power is related to the use conditions. For the same PTC heater with different use conditions, the power may differ several times. The electric heater has fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency.
