ABSOPULSE Electronics is an original equipment manufacturer (OEM) of rugged, high performance, EN50155 compliant-switching power supplies for railway and other severe environments.
Our heavy-duty DC/DC power converters, AC/DC power supplies, rectifiers and battery chargers, DC/AC sine-wave inverters and modular power systems operate in onboard and track-side electronic systems in major railway projects around the world. These include light rail, trams, overhead trains, underground and other mass transit systems, freight trains and mining locomotives.
Custom and standard railway quality switching power supplies
ABSOPULSE can meet an extensive range of electrical and mechanical configuration requirements, with modified existing designs or fully custom solutions. Output power levels are available from a few watts to several kilowatts. Selecting from a broad range of our field proven railway quality designs, we deliver rugged power conversion solutions, keeping design costs low and lead times short.
Our power supplies are designed and built for a long operational life in severe environments. High quality designs with traditionally large design headroom and the exclusive use of components with established reliability over many years contribute to high MTBF. All heat generating components are cooled by conduction cooled heat-sink blocks for optimum thermal performance. High efficiency, full electronic protection, and surge and transients protection also contribute to product reliability.
We have an ongoing R&D program which ensures that we remain innovative and are able to provide solutions and respond to all customer requirements.
