PTC Heater pellet
Detailed description of constant temperature and temperature regulation of PTC ceramic resistor (PTC thermistor):
PTC heating element once exceeds the Curie point temperature, the resistivity suddenly increases, the current dropped to a stable value, to automatically control the temperature, the purpose of constant temperature, without additional temperature control circuit device, PTC heating thermostat, thermostat , Special features from the temperature control, but also according to different temperature requirements through the formula to adjust the Curie temperature of PTC components.
Features:
1: PTC heating thermostat automatically
2: When the PTC heater is used to heat the liquid (such as water), the PTC resistor will not be damaged after the liquid is dried.
3: PTC long life, under normal circumstances, the life expectancy of up to 10 years;
4: Operating voltage 6-240V, when the operating voltage changes 2 times the surface temperature changes very small.
Applications:
Bottle thermostat, mosquito killer, electrochrome, curling iron, electric mosquito repellent, hair clipper, hair curler, heater, air conditioner, electric heating plate (plate), electric kettle, hand warmer, thermotherapy device , water heaters, dryers, yogurt machines, and other heating appliances.
According to customer requirements design different sizes, power!
| 1.Configuration. | |||||||||
| There are three types of structures, electric contacts on large sides, electric contacts on one side (the number of China national patent 201120015949.0), used for SMT. |
| For customer’s convenience, we provide assembled heating elements: PTC heating element with insulator and wire, PTC heating element with shell, PTC air heater,PTC for hair straightener, PTC for curler, PTC with resin coating, PTC for water heater, refering to other webpages. | |||||||||
| 2. Some samples of uses. | |||||||||
| Dryer, air heater, air condition heater, mosquito killer, car's heater, humidifier, de-humidifier, heating-plate, massager, physical therapy machine, hot glue-gun, hair crimper, hair straightener, coffee /milk warmer, water boiler, and so on. PTC is very suitable as a heating element, if the surface temperature on end product was under 260℃. | |||||||||
| 3. Notice in appliance. | |||||||||
| 1) The surface temperature on PTC can be controlled by itself, so that control circuit and protecting circuit may be omitted in most appliances. | |||||||||
| 2) It can be used for heating liquid, and it’s no problem without liquid immerging. | |||||||||
| 3) It can be used for heating air with fan blowing, and it’s no problem without blowing. | |||||||||
| 4) There are four electrodes coating to be selected: nickel +silver，melt-jet aluminum, screen print aluminum+silver, screen print zinc +silver. | |||||||||
| 5) Our PTC has very good operating life, 10 years or longer is possible. | |||||||||
| 6) Reliable, over temperature was impossible. | |||||||||
| 7) The surface temperature increases (or decreases) about 8℃, when supplied voltage increases (or decreases) 2 time. 100V to 240V applied voltage is impossible for same PTC heater | |||||||||
| 8) If customer requires PTC with wire, insulator, or shell, please select other types manufactured by our company. | |||||||||
| 9) Parallel connection is necessary for two or more PTC connection. | |||||||||
| 10) The steady state power may be very different with different applied condition for same PTC. The faster is the heat conduction, the higher is the steady state power. | |||||||||
| 11) In the most case, the type of two electric contacts on large sides was suitable; but in some appliance, we use other electric contacts. | |||||||||
