Note: The surface of the product is electrified. Caution should be taken when using it. Feature: The service life of the product is long. The general standard is that the power attenuation after 2000 hours is less than 10%. 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. 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. The product can be dried for a long time and is suitable for heating solids and gases. 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. Specification: Power: 50W; 100W (Optional) Voltage: 12V; 24V(Optional) Product dimension: 74*22mm / 2.9*0.9in(Ripple length: 52mm) Surface temperature: 20010 Heating object: Solid and gas Theoretical service life: >3 Year Package list: 1 * Ripple Element Heater Note: The actual product color may deviate from the photo due to light.
