DC/DC Converters for Transportation Applications
Off-highway vehicles use high-voltage traction batteries for the main motive power, but they need rugged DC/DC converters to provide safe low-voltage supplies to charge the on-board 12-V or 24-V batteries. The RMOD series are exceptionally rugged, compact, and sealed DC/DC converters, specifically designed for use with off-highway electric vehicles offering a range of solutions from 300W up to 600W, which can be chassis-mounted to avoid the need for cooling fans.
Their applications are in people movers such as airport shuttles and golf carts; harsh outdoor environments such as construction, mining, or parks and gardens; or indoor environments such as pallet loaders, forklift trucks, and automated guided vehicles.

The SD1200 series is a 1.2kW DC/DC converter, available from RECOM, with flexible input/output voltage levels. With railway application approvals, the product has five DC input ranges available covering 16.8V to 170V and three DC output variants at nominal 24V, 48V or 110V.
The SD2800 series is also available, a non-isolated 2.8kW DC/DC converter with a selection of nominal input/output combinations. The product can also optionally be powered from three-phase low voltage AC.
In industry, fork-lift trucks and other materials handling equipment often use traction batteries rated from 320V to 600V. The SD4000 series of on-board power supplies generates optionally 24V or 48V from the high voltage battery and is rated at 4kW with high efficiency. The 19“ rack product can be baseplate- or liquid-cooled.
