PTC Finned Resistor Air Heaters
PTC ’s (Positive Temperature Coeffi cient). elements are self-limiting and self. regulating heating elements which will. not exceed a preset temperature. This. effect is achieved by the material that. composes the PTC. It has a dynamic. resistance which increases dramatically. once the target temperature is reached. The increase in resistance will drop the. current draw to almost zero. Once heat. has dissipated from the heater and. more current is required to warm up the. heater... (read more)
