PTC product has an automatic energy-saving features, the heater when the ambient temperature is raised, the power will be gradually reduced, only 90% of rated power, 80%, or less. Long life: when in normal use PTC products is not damaged because of their own reasons, or even thousands of times repeatedly switch has no effect on its performance, a measure of its life is its degree of aging. General standards for power decay after 2000 hours is less than 10%. Safety, surface insulation. Heat the solid and the gas. Tips: 1. Be careful when use it. 2. This is a kind of Surface-Electrified PTC heater. 3. When the heater is working, the aluminum parts are conductive.
