Boxborough, MA – SynQor, Inc., announces new additions to its RailQor Transportation product line.  These new high power, high efficiency DC-DC converters are based on SynQor's next generation, isolated, fixed frequency synchronous rectifier technology.  The RailQor converters are designed to provide extremely high-power conversion efficiencies throughout the entire output power range.  The high efficiency characteristics of these bricks allow designers to run these units without heatsinks in enclosed environments, with no air flow at temperatures as high as 85 °C.

The modules are encased to operate in the harshest transport and industrial environmental conditions.  The ultra-wide input range of the RQ90 and RQ1B allows designers and integrators to power a large variety of products with a single part type.  The impressive power density of the modules helps optimize space in an industry where space is at a premium.  SynQor's field proven, highly reliable technology shortens design cycles and helps designers/integrators yield reliable dependable solutions for the very competitive rail and transport markets.
