SynQor, Inc. announces the RQ1BxxxHZ and RQ68xxxHZ, the new additions to its railway transportation product lines.  These high power, high efficiency DC-DC converters for railway applications 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 modules are encased to operate in the harshest transport and industrial environmental conditions. The ultra-wide input range of the RQ68 and RQ1B allows designers and integrators to power a large variety of products with a single part type. The outputs can be adjusted between -20% and +10% of the nominal output voltage of the converter. Multiple converters can be integrated for increased output power or to support redundancy. The impressive power density of the modules help 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.
