If the heater is run at 100% duty cycle, the current quickly drops to 3amps (which is acceptable). On this Wikipedia the language links are at the top of the page across from the article title. A heating element is a resistor tuned to produce as much heat as possible when current is passing through it. PTC ceramic (usually barium titanate, BaTiO3) is so named because it has a positive thermal coefficient of resistance, which means resistance increases upon heating. PTC Surface Heaters utilize aluminum housings for highly effective heat transfer to flat surfaces. The forced air can also be channeled through ductwork or to another location. Go to the Product Overview for this category. The heating element is often constructed of a PTC thermistor. Nevertheless, a self-regulating heating element may still be used to keep the heating element from damaging itself or other parts of the heater. When power is first applied to the cold PTC heating element, it has a low resistance and draws a large amount of current. When a motor is overloaded or rotation of a motor is stopped (locked), an overcurrent flows through the motor.

The PTC resistor (also known as PTC thermistor) is an electronic component that changes its resistance as a function of temperature. Asking for help, clarification, or responding to other answers. I doubt they chose to have a PTC heating element - rather they had little choice as most metals and alloys have a positive temperature coefficient. Resistors come in many shapes and sizes and have datasheets which rate the temperature it will reach with 'x' amount of current passing through it. Huge spikes are handled with huge snubbers :D seriously, just start at like 5% duty and monitor the current to feed back and heat it gradually, Driving / controlling PTC heating element, How Intuit democratizes AI development across teams through reusability. can be used as wild cards. PTC thermistor If the PTC heater is used to the heater the cold wind ,it will not be destroyed when. For telecom . The PTC then enters a high ohmic state, thus reducing the malfunction current to a lower level that is not dangerous. As it heats up, the resistance increases and the current draw decreases. Conventional heating elements are constrained to be long and thin (often coiled to save space) to prevent current hogging.
