DC/DC voltage converter 24 V/12 V
Real game changers: HELLA DC/DC converters 24 V/12 V convert the electrical energy from 24 V vehicle electrical systems to 12 V. With the help of these 24 V/12 V converters, 12 V loads can be used in a 24 V-based E/E architecture such as fans, lamps, and navigation and infotainment systems.
The HELLA DC/DC converters 24 V/12 V are extremely easy to integrate into the vehicle, as they do not require a data interface. They impress with a high efficiency of up to 90% and ensure reliable operation of 12 V devices. The voltage converters accept a wide range of input voltages from 18 V to 32 V, and provide stable output power at 13.5 V and up to 20 A rated current. Passive air cooling limits maintenance to an absolute minimum.
