The different watt of PTC heater in different working condition
The higher the surface temperature of PTC, the higher the power. PTC electric heater use note： PTC heater has the characteristic of automatic constant temperature, do not need the temperature control system, directly electrify PTC heater. When the PTC heater chip is used to heat liquid such as water, the heater chip will not be damaged after the liquid dries. The PTC heater chip will not be damaged if it is used for heating cold air without supplying air. Long life, in the normal environment, the life of more than 10 years. Reliable operation, the use of PTC heating chip internal characteristics control temperature, never exceed the temperature. Extreme amplitude of operating voltage: When the operating voltage changes by twice, the surface temperature changes very little. When using more than one PTC heater chip, the electric ball valve should not be connected in parallel or in series. The thermal power of PTC heater chip varies greatly under different heat dissipation conditions. The heating power is stable from large to small after being electrified. The stable power is related to the service conditions. If the same PTC heater is used in different conditions, the power may differ by several times.
