Bel Fuse Inc. has released the Bel Power Solutions 700DNG40-24-8, the second generation 4kW liquid-cooled DC-DC converter. The unit creates DC voltages in HEVs and EVs suitable to power low-voltage accessories, replacing a conventional alternator.

Housed in a compact design weighing just 4.5kg, the unit is suited for various deployments in construction, mining, bus and trucking, along with marine and ground support equipment.

The device offers high efficiency of up to 95%, high reliability, low output voltage noise, and excellent dynamic response to load/input changes. Also, the converter is parallelable up to eight units and incorporates optional UDS functionality, CAN FD and cybersecurity.

The new DC-DC converter is available immediately.
