Energy saving: PTC products have the characteristics of automatic energy saving. When the heater raises the ambient temperature, its power will gradually decrease, only 90%, 80%, or less of the rated power.3. Long lifespan: PTC products are not damaged due to their own reasons during normal use, and even tens of thousands of repeated switches have no effect on their performance. The standard for measuring their lifespan is their aging degree. The general standard is that the power attenuation after 2000 hours of operation is less than 10%.Note:1.Lead color is random.With 160 degrees normally closed temperature control protector, the heater should not be dry-dried.Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. .
