How to increase the power of the PTC heater?
The higher the surface temperature of the PTC, the higher the power. The use of ptc electric heater pay attention to that the ptc heater chip has the characteristics of automatic constant temperature, and the temperature control system is not required, and the ptc heater chip can be directly powered on.
When the PTC heater chip is used to heat liquid such as water, the heater chip will not be damaged after the liquid is dried. If the PTC heater chip is used to heat cold air without supplying air, the PTC heater chip will not be damaged. It has a long life span and can last for more than 10 years when used under normal conditions. It works reliably, and uses the internal characteristics of the PTC heating chip to control the temperature, never exceeding the temperature.
The operating voltage is very wide: when the operating voltage changes twice, the surface temperature changes very little. When electric ball valves use multiple PTC heater chips at the same time, do not connect them in parallel or in series. The heating power of the PTC heater chip varies greatly under different heat dissipation conditions. The heating power changes from large to small after power-on, and then stabilizes. The stable power is related to the use conditions. For the same PTC heater with different use conditions, the power may differ several times. PTC electric heater has fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency.
