Cool converters tackle transport

SynQor representative, Luso Electronics Distribution, has introduced the SynQor RailQor series of DC-DC converters aimed specifically at thermally demanding transportation applications. Available in quarter-brick packages, the RailQor converters deliver full power operation without a heatsink at 85°C under no-airflow conditions.

The new converters are designed to provide isolated DC power for applications such as LED displays, audio amplifiers, safety monitors, lighting and communications systems that meet the EN50155 European Standard.

Using SynQor’s synchronous rectifier based technology, these fixed-switching frequency converters are said to offer extremely high efficiency. Efficiencies exceed 85 per cent at as little as 10W output and 93 per cent at full load. The full operating temperature range is from –40 to 110°C baseplate temperature with airflow, or up to 125°C in natural convection environments.
