Railway & Harsh Enviroment Solutions

DC/DC Power Converters,  AC/AC Power Supplies and  DC/AC Sine-wave Inverters for Railway & Extreme Environments

ABSOPULSE specializes in the design, development and manufacture of heavy-duty DC-DC power converters, AC-DC power supplies, rectifiers and battery chargers, DC-AC inverters and complete power systems in 19" or 23" racks for railway environments.

We deliver cost-effective solutions for almost any electrical and mechanical configuration requirement, with output power ranging from a few watts to several kilowatts.

Today, ABSOPULSE's railway power conversion products operate in on-board and trackside electronic systems in major railway projects around the world - from light rail, trams, overhead trains, underground and other mass transit systems to mining locomotives. Our long-term customers include a few of the biggest names in the international railway industry.

ABSOPULSE power converters are designed and built for an operational life of up to 30 years in severe environments - our first major railway installation has been in operation for 27 years.

The reliability of our products is based upon high quality designs, traditionally large headroom, the exclusive use of qualified-in components with many years of established reliability and compliance with relevant, application-specific safety and emissions standards.
