RECOM’s new DC/DC withstands harsh environments seen in vehicle and boat applications.

Feb 11, 2026

The new RECOM RMOD4000 series of compact, plug-and-play DC/DCs is a cost-effective solution to provision of isolated 14V, 28V, or 56VDC network rails from a high input voltage between 180 and 950VDC from traction batteries. Up to 4kW is available depending on variant and input voltage, and a conversion efficiency of up to 95%, along with baseplate or liquid cooling options, results in cool running and high reliability and lifetime.

The output is fully regulated and protected against over-current, over-voltage, over-temperature and short circuits, while the input has under-and over-voltage lockout and active inrush suppression. An isolated CAN J1939 interface is provided to allow control and data monitoring, including output voltage adjustment. A separate hardware on/off control (ignition) and HV-interlock-function is included. As an added feature, an integrated OR-ing function is implemented, allowing paralleling of units for redundancy or increased power capability with active current sharing. Operating temperature is -40°C to +85°C with no derating.

Full reinforced isolation is provided to IEC62477-1, vehicle safety standards ISO6469-3 and ISO 7637 are met and the EMC standard ECER10 Rev 4 is certified (E-mark).
