DC DC 4:1 wide range input power converters in Automotive electronics filed DC DC power converters has the short design cycles,high reliable, system easy to update and advance features,which make the DC DC power converters widely used.CHONDA TECH push the new seriouse 4:1 wide range input power converters on the the market,with the sealed metal shell,high power density,small size for the automotive electronics field. The advanteages has two points: 1. As the automotive eletronics use 12V or 24V power supply,the voltage changes is extremely wide,if use the DC DC power converters input 2:1 will be limited during the working process,if the battery couldn't exchange,and hard to bear this voltage hit.Chonda tech design the 4:1 wide range input DC DC power converters,working temperature from -45 degree to 85 degree,solving the normal power converters lower adjust voltage faulty causing the power convertes couldn't used for automotive electronics field problem.This series power converters is popular used for 12V or 24V power supply autmotive eletronics field. 2. CHONDA TECH 4:1 wide range input DC DC power converers series,adopt the five side metal sealed,isolated 1500VDC,can isolate the automotive electonics powe supply systems super interfence,MTBF more than 100 0000 hours,high efficiency working and stablized working,and enhance the automotive electonics power supply much stronger than before.
