Eaton introduces 48 V DC-DC converter for off-highway vehicles in harsh environments – Charged EVs


Power management company Eaton has introduced a higher-capacity version of its 48 V DC-DC converter.

The new converter has up to 40 A of output current capacity and is intended for installation in on- and off-highway vehicles. It is hardened for use in harsh environments, features an air-cooled design utilizing natural convection, and can operate at ambient temperatures up to 185° F (85° C).

“These are environmental extremes with adverse conditions, shock and vibration that require robust protection features,” noted Ben Karrer, Head of Engineering for Low Voltage and Power Conversion at Eaton’s Mobility Group.

The new equipment will reduce weight and save space, according to the company.

The converters step down power from a 48 V system to 12 V to provide power to accessory equipment.   They support the Controller Area Network (CAN) bus specification, which allows the converters to communicate with other electronic vehicle controls.
