New Energy Bus 450V-750V HV PTC Heater Windshield Defroster Unit
The New Energy Bus 450V-750V HV PTC Heater Windshield Defroster Unit is a dedicated high-voltage heating and defrosting equipment for new energy vehicles (electric buses, hybrid buses, fuel cell buses). It adopts high-voltage PTC air heating technology, with a working voltage range of DC 450V-750V, perfectly matching the mainstream 600V high-voltage platform of new energy buses. It integrates two functions: windshield defrosting/defogging and cab heating, which is an essential core component for the thermal management system of new energy buses, especially suitable for alpine regions.
