Characteristics Of PTC Ceramic Heating Elements
The Positive Temperature Coefficient Resistance (PTCR) was first discovered in 1950 by Haayman of Phillips in the Netherlands. Doping a small amount of rare earth raw materials into BaTiO3 turns the original dielectric ceramic into a semiconductor ceramic. The resistance of this semiconductor ceramic changes with temperature and has a positive temperature coefficient relationship, so it is called ceramic PTC.
Ceramic PTC is mainly used in control and heating products, among which heating products are mainly used in small household appliances, auxiliary heating of household air conditioners, auxiliary heating of automobile air conditioners, power battery heating, energy storage battery heating, hairdressing appliances, hanging irons, air heaters, Rice cookers and liquid heaters, etc.
1. Energy saving
It has constant temperature characteristics. It can automatically reduce the heating power when the ambient temperature is increased, and automatically increase the heating power when the ambient temperature is lowered, that is, adjust its own heating power output according to the change of the ambient temperature, and can control the power consumption of the heater to a minimum. The effect of automatic energy saving. These are things that traditional heating products such as electric heating tubes and resistance wires cannot do.
2. Security
The maximum temperature can be determined by design according to product requirements. The PTC automatic constant temperature feature avoids dry burning and overheating.
3. Long life
1 min "ON" / 1 min "OFF" cycle 10,000 times, or the heater has been working continuously for 1000 hours, and the power attenuation is ≤10%.
4. Fast heating
The heating power of the PTC heater increases with the decrease of the ambient temperature. At the same time, there is an impulse power (current) higher than the rated power when starting, so the heating speed is faster when the ambient temperature is lower.
5. Ultra-low temperature start
Even if it is minus 40 degrees, it can start and heat quickly as usual.
6. Wide voltage range
It can work normally between 3V-700V.
