Will it cuases probelm when the temperature of PTC surface is high?

The higher the surface temperature of PTC, the higher the power. Pay attention to the use of PTC electric heater, it has the characteristics of automatic constant temperature. It doesn't need a temperature control system but can be powered directly. When using a PTC heating plate to heat liquid (such as water), the heating plate will not be damaged after the liquid is dried. If the PTC  heater is used to heat cold air, the high temperature fan PTC heater also will not be damaged when there is no air supply. It has a long service life and can be more than 10 years in normal environment. The operation is reliable, and the temperature is controlled by using the internal characteristics of PTC heater. Working voltage non constant width: the surface temperature changes very little, even when the working voltage changes 2 times. If multiple PTC heating plates are used together, they should be connected in parallel rather than in series. Different heat dissipation conditions make the heating power of PTC heater change greatly. After power on, the heating power is stable from high to low. The stable power is related to the service conditions. The power of the same PTC heater may be several times different if the service conditions are different. The electric heater has fast thermal response, high temperature control precision and high comprehensive thermal efficiency.
