Air conditioner PTC heater which can change the temperature without manual. PTC heating elements are made into a large number of electric heating components to assist the heat loss of corrugated aluminum strips for forced air heating. It is composed of PTC heating sheet, electrodes, thermally conductive insulating alumina or insulating film and heat-dissipating corrugated aluminum strip.
1. As a constant temperature heater for solids, the applicable heating temperature: 0 to 300 ℃;for the normal heating temperature, the minimum one is 50℃ while the maximum is 300℃. The workable ambient temperature is -40℃ to 250℃.
2. Working voltage: 3.7V to 420V, AC and DC. It should be noted that when the working voltage is not enough, the room temperature resistance of the PTC will lower which the same as the change rate of the resistance temperature, and then the thermostatic temperature accuracy is getting bad; at the same time, due to the heating power is not gigh, it slows down the heating rate and cannot reach the temperature you want.
3. Surface temperature:
At an ambient temperature of 25 ± 5 ℃, the temperature tolerance as follows:
1. Automatic power adjustment.
2. High heat exchange rate.
3. Good energy saving effect.
4. High safety performance.
