Feature: 1. Constant Temperature: PTC heating element uses ceramic constant temperature heating technology to continuously output heat and automatically work at constant temperature. 2. Rapid Heating: PTC quickly converts electrical energy into heat energy after power on, and conducts it to the surface of the aluminum shell within 10S (to be used with a fan). 3. Safe and Reliable: The ceramic air heating element has no open flame, no redness, no toxic and harmful gases, and is safe and reliable to use. 4. Humidity and Temperature Resistance: PTC ceramic air heater is resistant to humidity and temperature, and can operate in a <95% humidity environment for a long time. Ideal for heating objects and dehumidifying spaces. 5. Long Lasting: Working voltage of PTC ceramic heating element: 24V, steady state power: 800W±30%, withstand voltage: 40V. It can work uninterrupted 7x24 hours, continuously provide heat source, and have a life span of more than 50,000 hours. Specification: Item Type: PTC Heating Element Material: PTC, Aluminum Heating Material: PTC Thermistor Size: Approx. 150 x 68 x 18mm/5.9 x 2.7 x 0.7in Heating Method: Conduct Heat Through Flowing Air Temperature Error: ±10℃ Steady State Power: 800w±30% Impact Power: ≤900w±30% Uses: Suitable for Heating Objects and Space Dehumidification.
