Specification: Product Name :Aluminum PTC Heating Element Size(Approx.) :77626mm Voltage: 12V 24V 36V 48V 110V 220V AC/DC Temperature: 60 80 100 120 150 180 200 230 270 Degree Celsius Heat Material: Thermistor Heat Methods: Heating Conduction Lead Wire: High Temperature Line Surface Insulate: Yes Feature: The temperature of the product identification refers to the ambient temperature of 24 degrees, the maximum temperature of the product in the air for 1 to 2 minutes, and the temperature difference of 10 degrees. For example: 220 degree product, the highest temperature in the air is 210~230 degrees (may not show 220 degrees) Hope buyers can understand. The PTC part is used for heating air or solid. It's meterial has a characteristic that it is constant temperature on the surface. The power consumption of the heater is not fixed. The better the heat dissipation, the greater the power. Advantage: Safety, surface insulationheat up quickly, long service lifeconstant temperaturehigh power, easy use, high reliability. Application: Heater for water, cup, gas, application as hair straightener, yogurt maker, instrumentation dehumidification, chocolate extrusion, coffee maker.car and components preheating.
