220V Underfloor Heating Film PTC Heating Film Frequency Conversion Heated Far Infrared Floor Heating Heated Mat Film

What is PTC?The PTC means Positive Temperature Coefficient, it refers to kinds of specia materials, the electrical resistance of the PTC materials will increase when the temperature of the material is raised, and also the electrical resistance of the material will reduce when the temperature is reduced.What is PTC Heating Film?The PTC heating film is a new type and updated warm floor product based on ordinary heating film.Temperature limiting function of electric heating film. The working principle is that if the temperature rises, the resistance will increase, so that the current will decrease, and the temperature will not increase endlessly. Conversely, if the temperature drops, the resistance will decrease, the current will increase, and the temperature will not decrease endlessly. Thus, the temperature is controlled within a safe and reasonable safety DISTANCE. To achieve the effect of energy saving and power saving.Package included:1 X Underfloor Heating FilmSpecification:Rated power: 220W/m (+-10%)Working voltage: 200~240V AC 50/60HzWidth: 50cmInfrared wave length: 8~16umThichness: 0.338mm (the 0.25mm thickness heating film is not safe to use under the floor)Features:1.
