DC/DC Converters in Transportation
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 the on-board 12V or 24V batteries. The RMOD series is an exceptionally rugged, compact, and sealed DC/DC converter series, specifically designed for off-highway electric vehicles and offering a range of solutions from 300W to 600W, which can be chassis-mounted to avoid needing cooling fans.
Applications include 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 from RECOM, offering flexible input/output voltage levels. With railway application approvals, this rail power converter has five available DC input ranges covering 16.8V to 170V and three DC output variants at nominal 24V, 48V or 110V. Also available is the SD2800 series, a non-isolated 2.8kW DC/DC converter with a selection of nominal input/output combinations. This product can optionally be powered from a three-phase low-voltage AC source.
In industry, forklift trucks and other materials handling equipment often use traction batteries rated from 320V to 600V. The SD4000 series is an on-board traction battery converter that generates 24V or 48V options from the high voltage battery and is rated at 4kW with high efficiency. This 19" industrial power supply can be baseplate- or liquid-cooled.

DC/AC Converters in Transportation
DC/AC converters, or inverters, are an essential part of a complete transportation power supply architecture. These power converters transform DC voltage from a battery bank into a stable, regulated AC sine wave output. In transportation applications, these inverters are used to power auxiliary loads such as HVAC systems, lighting, communication equipment, and utility outlets for passengers or maintenance crews. A vehicle power converter or rail power converter in this category must be highly robust, offering protection against the shock, vibration, and wide temperature ranges typical of mobile environments. RECOM’s designs focus on high-efficiency, compact, and sealed solutions to ensure reliability for these critical mobility power solutions.
