Chassis Mount DC/DC Converters

40–4000W
RECOM’s chassis mount DC/DC converters with a range of 40–4000W are engineered for high-power architectures where mechanical durability and simplified thermal management are critical. Designed for direct installation onto metal plates or frames, these industrial DC/DC power supplies provide a "ready-to-use" solution for the most demanding transportation, energy, and automation sectors.

Our isolated chassis mount converters feature rugged metal housings that act as integrated heatsinks, protecting electronics from extreme vibration, dust, and temperature swings. Unlike board-level modules, these units often include built-in filtering and protection, making them ideal for mission-critical systems requiring robust galvanic isolation and continuous high-capacity delivery.

Whether you are powering heavy-duty machinery or railway infrastructure, RECOM’s regulated chassis mount converters offer a scalable, dependable solution. Their wide input ranges and flexible mounting options reduce engineering complexity and streamline the deployment of high-power circuits.

As a global leader in power, RECOM supports its rugged DC/DC converter portfolio with long-term availability and deep technical expertise. Explore our full selection below to find the high-efficiency solution that meets your specific environmental and mechanical requirements.

    Frequently Asked Questions

    Chassis mount DC/DC converters provide high-power voltage conversion in systems where PCB mounting is not feasible. They are commonly used in industrial machinery, railway rolling stock, and electric vehicle (EV) charging infrastructure. Their enclosed, rugged design allows them to be bolted directly to a vehicle frame or a control cabinet plate.
    The primary advantage is that they are "ready-to-use." Unlike board-mount bricks, chassis mount units typically include built-in terminal blocks for easy wiring, integrated heat dissipation, and internal EMC filtering. This eliminates the need for a custom PCB and additional external cooling components.
    To ensure system-wide reliability, RECOM’s high-power converters include a comprehensive suite of protections, including over-temperature shutdown, short-circuit protection, over-voltage protection (OVP), and robust galvanic isolation. This prevents a fault in the power stage from damaging sensitive downstream equipment.
