Gmunden, February 13th, 2026 – RECOM’s New DC/DC withstands Harsh Environments Seen in Vehicle and Boat Applications.
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).
The RMOD4000 series is presented in a water- and dust-proof cast aluminium enclosure to IP67 standard and can be baseplate or water-cooled with integrated coolant ports. Body dimensions are 316 x 254 x 83mm, and sealed, plug-in connectors are provided for input and outputs.
Applications for the product are as an on-board DC/DC converter for battery powered on- and off-highway vehicles, such as forklifts, golf carts, AGVs, loaders, tractors, ships, and electric boats, in the areas of marine, material handling, construction, airports, E-mobility as well as for battery powered boats and marine systems.
“These products couldn’t be more user-friendly” comments Marco Kuhn, product manager DC/DC Plug & Play of RECOM. “They meet all the necessary environmental standards for on-board DC/DCs in harsh mobility applications while providing class-leading electrical performance in a compact package”.
Parts include a two-year warranty. Samples and OEM pricing are available from all authorized distributors or directly from RECOM.
