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. These include light rail, trams, overhead trains, underground and other mass transit systems, as well as mining locomotives. Our long-term customers include a few of the biggest names in the international Railway Industry.

Absopulse power supplies are designed for an operational life of 20 to 30 years in severe environments - our first major railway installation has already been in operation for 25 years.

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

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