Precautions for the use of PTC heaters:
1. The feature of the PTC tower heater is automatic constant temperature, which does not require any temperature control system, just start the PTC heating plate directly.
2. When the PTC heating sheet is used to heat liquid (such as water), the PTC heating sheet will not be damaged after the liquid is dried.
3. If the PTC heating sheet is used to heat the cold air, the PTC heating sheet will not be damaged without the need for air supply.
4. The PTC heating element has a long service life and can be used in a normal environment for more than ten years.
5. The PTC heating element works reliably, and the internal characteristics of the PTC heating element are used for temperature control, and there is basically no over-temperature phenomenon.
6. The working voltage of the PTC heater is very wide: when the working voltage changes by 2 times, the surface temperature change is still small.
7. When multiple PTC heaters are used at the same time, they cannot be used in series, but should be used in parallel.
