1. The PTC heating plate has the characteristics of automatic constant temperature, no temperature control system is needed, and the PTC heating plate can be directly energized.
2. When the PTC heating film is used to heat liquid (such as water), the PTC heating film will not be damaged after the liquid is dried.
3. If the PTC heating plate is used to heat the cold air, the PTC heating plate will not be damaged when the air is not supplied.
4. Long service life, under normal environment, the service life can reach more than 10 years. PTC heater manufacturers
5. Reliable work, use the internal characteristics of the PTC heater to control the temperature, and never over-temperature.
6. The working voltage is very wide: when the working voltage changes twice, the change of the surface temperature is very small.
7. When multiple PTC heaters are used together, they should be connected in parallel, not in series.
1. After the liquid is dried, the PTC heater will not be damaged.
2. 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.
3. The service life is long, and the service life can reach more than 10 years when used in a normal environment.
4. The operation is reliable, using the internal characteristics of the PTC heater to control the temperature, and it will never over-temperature.
5. The operating voltage is very wide: when the operating voltage changes twice, the change in surface temperature is very small.
6. When multiple PTC heaters are used together, they should be connected in parallel, not in series.
7. Different heat dissipation conditions make the heating power of PTC heaters vary greatly. PTC heater manufacturers
8. The heating power is increased from large to small after power-on, and then stabilized. 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.
9. 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.
10. PTC has a high reliability and a long lifespan, but if it is not installed properly, the product will show signs of unstable power and temperature.
11. When multiple PTCs are used together, they should be connected in parallel, not in series.
The pressure resistance performance of PTC heaters firstly depends on the pressure resistance of PTC components. Through optimized formula design, perfect process flow, and pressure full inspection control, the higher pressure resistance of the heater is more than 600VAC/1min.
In the structural design of the water heater, because it is a fully enclosed structure, the heat of the PTC element is not easy to dissipate, so a reasonable heat dissipation design is very important. At present, the surface of the water heater has a higher power density of more than 10W/cm2.
At the same time, the fourth-generation water heater products have high insulation reliability, can pass 3750VAC/1min, leakage current is less than 0.5mA/KW, and will never be damaged.
