Relec’s New Range of DC DC Converters

22nd January 2017

The HP series of 10:1 wide input 192W dc dc converters supplied by Relec Electronics are the ideal solution where enhanced durability power conversion products are required for use in harsh environments.

The HP series power converters are manufactured by Bel Power Solutions who has over 40 years’ experience in supplying the railway industry throughout the world. The range has a tried and tested track record and has the Melcher™ brand name that is synonymous with quality design and engineering.

The extremely wide input range of 16.8Vdc to 137.5Vdc with dynamic transient deviations to 12.5Vdc and 154Vdc for 2 seconds respectively makes these converters particularly suitable for railway applications and can be supplied by all common dc traction supplies of 24V, 36V, 48V, 72V, 96V & 110V nominal voltage.

Features include high efficiency, high reliability, low output noise, and excellent dynamic response to load/line changes. The converters comply with EN50155 and EN50121-3-2; IEC/EN 60950-1; UL/CSA 60950-1 2nd Ed.; IEC61000-4-2, -3, -4, -5, -6; fire and smoke standard EN45545.

Available as single, dual, triple and quad outputs as combinations of 5V, 12V, 15V, 24V, 48Vdc and is configurable up to 96Vdc; LED indicators display the status of the converter and allow for visual monitoring of the system at any time.

The converters are housed in a rugged cassette case, that may either be plugged into a 19” rack system according to IEC60297-3, or be chassis mounted. Cooling plates are available for conduction cooled applications or heat-sinks for convection cooling.
