PTC heaters for electric automobile

 

Application Area

Applied in heaters and defrosters on electric, hybrid electric automobile,and bus

Features & Advantages

Electric and hybrid automobile output DC voltage normally between 320VDC to 540VDC.The highest range may reach 700VDC to 900VDC.Thus, the basic requirement for heating or defrosting on such automoblile should be safety under long-term high voltage.Our products are designed to fulfill these requirements with following characteristics.  

1 Withstanding high voltage of more than 1300VDC to ensure safety under long-term high voltage; 

2 Rapid heating up under low temperature to gurantee quick lauch even under -40℃ ambient. 

3 Tiny decay under high DC voltage so that excellent heating performance remains even after long-term use.  

4 Any curie temperature could be reached between 140℃-250℃;   

5 More than 10 years service life
