Note: _x000D_ The surface of the product is electrified. Caution should be taken when using it. _x000D_ _x000D_ _x000D_ Feature: _x000D_ The service life of the product is long. The general standard is that the power attenuation after 2000 hours is less than 10%. _x000D_ 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. _x000D_ PTC products have incomparable advantages over traditional heating elements, such as constant temperature heating, no open fire, high heat conversion rate, minimal influence by power supply voltage, etc. _x000D_ The product can be dried for a long time and is suitable for heating solids and gases. _x000D_ This product is generally used in wax melter heater, steam generator heater, boiler heater, water heater, insulating cup heater, milk heater, coffee heater, glue machine heater, hot melt gun heater, chocolate extruder heater, etc. _x000D_ _x000D_ Specification:_x000D_ Power: 50W; 100W (Optional)_x000D_ Voltage: 12V; 24V(Optional)_x000D_ Product dimension: 74*22mm / 2.9*0.9in(Ripple length: 52mm)_x000D_ Surface temperature: 20010_x000D_ Heating object: Solid and gas_x000D_ Theoretical service life: >3 Year_x000D_ _x000D_ Package list:_x000D_ 1 * Ripple Element Heater_x000D_ _x000D_ Note:_x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
