Feature:1. Constant Temperature Heating: PTC heater plate uses ceramic constant temperature heating technology to continuously output heat and automatically work at constant temperature.2. Polyimide Film: The interior of PTC heating elements uses polyimide film to wrap the chip, which is insulating and temperature resistant.3. High Safety: PTC heating elements plate has no open flame, no redness, no toxic and harmful gas, suitable for humid environment.4. Rapid Heating: PTC quickly converts electrical energy into heat energy after power on, conducts it to the surfaces of the aluminum shell within 10S, and can dry for a long time.5. Long Service Life: Thermostatic heater continues to provide heat source life for more than 20,000 hours.Specification:Item Type: PTC Heater PlateMaterial: Aluminum Alloy, PTC, Polyimide FilmLead Material: High Temperature Resistant WireProduct Size:Approx. 25 x 21 x 5mm / 1.0 x 0.8 x 0.2inUse Voltage: 220VSurfaces Temperature: 230Lead Length:Approx. 15cm / 5.9inTemperature Error: 10.Package List:5 x PTC Heater PlateNote:Please supply power according to the voltage used.
