1) The PTC heater has the characteristics of automatic constant temperature, no temperature control system is required, and the PTC heating element can be directly energized.
2) When the PTC heater is used to heat liquid (such as water), the PTC heating element will not be damaged after the liquid is dried.
3) If the PTC heater is used to heat the cold air, the PTC heating element will not be damaged when the air is not supplied.
4) There are four kinds of electrodes for customers to choose: printed aluminum, printed aluminum + silver, melt-blown metal aluminum, electroless nickel + silver.
5) Long service life, under normal environment, the service life can reach more than 10 years.
6) Reliable work, use the internal characteristics of the PTC heater to control the temperature, and never over-temperature.
7) The working voltage is very wide. When the operating voltage changes twice, the change in surface temperature is very small.
8) This product does not have wires and insulation layers. Customers also choose products with wires and insulation layers, or products with shells.
9) When multiple PTC heating elements are used together, they should be connected in parallel, not in series.
10) Different heat dissipation conditions make the heating power of the PTC heating piece very different.
After the liquid is boiled out, the PTC heater will not be damaged.
If the PTC heating plate is used to heat the cool air, the PTC heating plate will not be damaged when the air is not supplied.
The service life is long, and the service life can reach more than 10 years when used in a normal environment.
Reliable operation, using the internal characteristics of the PTC heater to control the temperature, and will never over-temperature.
The operating voltage is very wide: when the operating voltage changes twice, the change in surface temperature is very small.
When multiple PTC heaters are used together, they should be connected in parallel, not in series.
Different heat dissipation conditions make the heating power of PTC heaters vary greatly.
The heating power increases from large to small after power-on, and finally stabilizes. The stable power is related to the operating conditions. If the operating conditions of the same PTC heater are different, the power may differ by several times. The faster the heat dissipation, the greater the stable power; the higher the surface temperature of the PTC, the higher the power.
The surface temperature of the PTC heating element is controlled by the PTC itself, and can also be controlled by disconnecting the circuit, but it cannot be controlled by the regulated voltage.
PTC itself is very reliable and has a long lifespan, but if it is not installed properly, the product will show signs of unstable power and temperature.
When multiple PTCs are used together, they should be connected in parallel, not in series.
external structure.
There are 3 types of chip PTC heating element structures, double-sided electrode lead-out type, single-sided electrode lead-out type, and side electrode lead-out type.
Examples of uses.
Heater, air conditioner heating, clothes dryer, mosquito killer, motorcycle carburetor, automobile choke door, automobile cold-start preheating, electric humidifier, electric instrument moisture-proof heating, electric heating plate (pan), massager, hyperthermia Instrument, glue gun, curling hair, hair straightener heating, hot coffee machine, milk heater, water boiler, water heater, steam beauty, etc. When the product terminal temperature is below 260℃, using PTC heating can maintain a constant temperature, without temperature control, compact structure and long life, which has great advantages.
3. Use caution.
1) The PTC heating element has the characteristics of automatic constant temperature, no temperature control system is required, and the PTC can be directly energized.
2) When the PTC heating element is used to heat liquid (such as water), the PTC heating element will not be damaged after the liquid is dried.
3) If the PTC heating element is used to heat the cold air, the PTC heating element will not be damaged when the air is not supplied.
4) There are four kinds of electrodes for customers to choose: electroless nickel + silver (weldable), melt-blown metal aluminum, printed aluminum + silver, printed silver zinc + silver (weldable), printed aluminum.
5) Long service life, under normal environment, the service life can reach more than 10 years.
6) Reliable work, using the internal characteristics of PTC to control temperature, never over-temperature.
7) The change of working voltage has relatively little influence on the surface temperature. When the working voltage is increased by 2 times (or decreased by 1/2), the surface temperature will increase (or decrease) by about 8°C.
8) This product does not have wires and insulation layers. Customers also choose our company's products with wires and insulation layers, or products with shells.
9) When multiple PTCs are used together, they should be connected in parallel, not in series.
10) Different heat dissipation conditions make the heating power of PTC very different.
