Power Solutions for Transportation

RECOM provides high-specification AC/DC on-board chargers and converters engineered for heavy-duty battery conditioning and vehicle power conversion:

• Programmable bidirectional on-board chargers and battery conditioners: Available with 2kW single-phase AC and 11kW three-phase AC input, supporting battery voltage ranges of 3 - 120VDC and 4 - 300VDC respectively. These units can be programmed to charge and discharge batteries for testing and conditioning, supporting battery service life and operational availability.
• Non-isolated step-down rectifiers: High-density 2.8kW converters for mobile applications can accept low-voltage, three-phase AC inputs such as nominal 24VAC or 44VAC and provide 14V or 28V auxiliary outputs.
• Cascadeable railway battery chargers: Three-phase rack-mount battery chargers complying with railway standards are available with 3.2kW, 4kW, or 5kW ratings, low-voltage DC outputs, and digital communications.

Off-highway vehicles use high-voltage traction batteries for main motive power, but they need a rugged vehicle power converter to provide safe, low-voltage supplies for charging on-board 12V or 24V batteries. Exceptionally rugged, compact, and sealed DC/DC converters are designed for off-highway electric vehicles and provide solutions from 300W to 4.2kW. Depending on input voltage and power level, these chassis-mounted converters use fanless baseplate or liquid cooling and support low-voltage auxiliary networks from traction batteries.

Applications: People movers (airport shuttles, golf carts), harsh outdoor environments (construction, mining, agriculture), and indoor logistics (pallet loaders, forklifts, AGVs).

DC/AC converters, or inverters, convert DC battery voltage into a stable AC output for auxiliary loads in transportation power architectures. In mobile transit and railway environments, these robust inverters power vital auxiliary loads, including:

• Climate Control & Safety: On-board HVAC systems and internal/external vehicle lighting.
• Connectivity & Infrastructure: Communication equipment and utility power outlets for passengers or maintenance crews.

For demanding transportation environments, RECOM offers high-efficiency inverter designs in compact 19-inch rack, open-frame, and chassis formats. Depending on the product, railway-qualified designs provide the mechanical robustness and environmental performance required for mobile and rail applications.
