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, no temperature control system is needed, and the PTC heater chip can be directly energized. 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 be used under normal conditions for more than 10 years. It works reliably, and uses the internal characteristics of the PTC heating chip to control the temperature, and never exceeds 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.
The electric heater has fast thermal response, high temperature control accuracy, and high comprehensive thermal efficiency.
The higher the surface temperature of the PTC, the higher the power. Pay attention to the use of ptc electric heater. The PTC heater has the characteristics of automatic constant temperature. It does not require a temperature control system. It can be powered directly. When the positive temperature coefficient heating element is used to heat the liquid (such as water), the positive temperature coefficient heating element will not be damaged after the liquid is dried. If the positive temperature coefficient heater is used to heat cold air, when there is no air supply, the high temperature fan positive temperature coefficient heater will not be damaged. The service life is long, up to more than 10 years under normal conditions.
Reliable operation, using the internal characteristics of the PTC heater for temperature control, over temperature. Working voltage non-constant width: When the working voltage changes twice, the surface temperature changes very little. When multiple PTC heating panels are used together, they should be connected in parallel, not in series. Different heat dissipation conditions make the heating power of the PTC heater vary greatly. The heating power is stable from high to low after energization. The stable power is related to the use conditions. For the same PTC heater with different use conditions, the power may differ several times. The electric heater has fast thermal response, high temperature control accuracy, and high comprehensive thermal efficiency.
