Railway & Extreme Environment Power Conversion Solutions

Absopulse specializes in the design, development and manufacture of heavy-duty switching power supplies for railway environments.

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

Our power supplies 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.

Absopulse’s rugged power conversion products are also installed in military, marine, airborne, industrial automation, automotive, oil exploration, power utilities and telecom environments, in many countries - all built to last for decades.
