ABSOPULSE Electronics is an original equipment manufacturer (OEM) of rugged, high performance, EN50155 compliant switch-mode power supplies for railway and other severe environments.

The company’s rugged power conversion products operate in on-board and trackside electronic systems in major railway projects in North and South America, Europe, Australasia, Asia and Africa.

Typical applications include signalling and communication systems, GPS systems, video surveillance and security systems, train control and monitoring systems and traction control systems.

Railway DC-DC converters, DC-AC sine wave inverters, AC-DC power supplies and battery chargers

ABSOPULSE product lines designed for on-board and trackside railway applications include:

Fully encapsulated, conduction/convection cooled railway quality DC/DC and AC/DC power supplies, DC/AC sine wave inverters. Encapsulation in a thermally conductive MIL-spec. silicon rubber compound ensures immunity to shock, vibration, moisture, humidity and wide temperature ranges.
Railway quality DC/DC and AC/DC power supplies, DC/AC sine wave inverters in IP66-rated enclosures for applications that require protection from the ingress of water from powerful jets, dust, fog, sand, oil, salt, insects and other environmental contaminants.
Low-profile, heavy-duty, railway quality DC/DC and AC/DC power supplies, DC/AC sine wave inverters and AC/AC frequency converters in chassis-mount, conduction/convection cooled vented enclosures.
Fully encapsulated railway quality DC/DC and AC/DC power supplies with pure convection cooling by heatsink assembly fins can be mounted to a chassis, uneven as well as thermally non-conductive surfaces. DIN-rail option available.
Railway quality modular power systems with DC/DC, AC/DC and DC/AC plug-in modules in 19in or 23in racks.
Heavy-duty, portable AC/DC battery chargers, DC/DC power converters and DC/AC sine wave inverters in portable, splash-proof enclosures.
  • DC/DC power converters
  • DC/AC sine-wave inverters, single or 3-phase combinations
  • AC/AC phase & frequency converters, single or 3-phase combinations
  • AC/DC power supplies, rectifiers and battery chargers
  • DC-output UPS systems
  • Complete power systems in 19in and 23in racks: DC/DC, DC/AC, AC/DC
  • Gate-drive power supplies for traction systems – up to 30kVA isolation, corona free

These products typically offer combinations of the following features, depending on specific model and customer requirements:

  • Any input and output according to requirements
  • Single or multiple outputs
  • EMI filtering to any standard, typically EN55022 Class B
  • Wide operating temperature ranges including -40°C to +70°C. Wider ranges are available
  • Wide range of options, including output fail alarms, redundancy, indicators, enable/inhibit and other controls
  • RoHS compliance

Customised and standard railway quality power conversion solutions

ABSOPULSE can meet almost any electrical and mechanical configuration requirement, modifying existing designs or creating fully customised solutions.

Output power levels are available from a few watts to several kilowatts. Selecting from a broad range of tested railway quality designs, we deliver rugged power conversion solutions, keeping design costs low and lead times short.

The company’s power supplies are designed 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 mean time between failures.

All heat generating components are cooled by conduction heat-sink blocks for optimum thermal performance. High efficiency, full electronic protection, and surge and transient protection also contribute to product reliability.

We have an ongoing R&D programme, which ensures that we remain innovative and are able to provide solutions and respond to all customer requirements.

Rugged mechanical designs

ABSOPULSE power supplies are ruggedly constructed and can be customised for specific mechanical requirements.

Standard mechanical packages and ruggedisation options include:

  • Chassis and wall-mountable units in vented conduction / convection or fan-cooled enclosures
  • DIN-rail and open-frame format available for many designs
  • Plug-in (Eurocard) format for modular power systems in 19in or 23in racks
  • Conformal coating and ruggedising are standard
  • Full encapsulation (potting) in a thermally conductive MIL-grade silicon rubber compound
  • Enclosure in rugged, IP66- or IP67-rated waterproof, dustproof and die-cast aluminum packages.

Railway standard compliance

ABSOPULSE railway power supplies are designed to meet rail-specific standards including EN 50155, EN 45 545-2, EN 61 000-4-2, EN 61 000-4-3, EN 61 000-4-4, EN 61 000-4-5, EN50121-3-2, EN 55022 Class B, RIA 12, IEC 571, IEC 61373 shock/vibration and RIA 13 and RIA 20 mechanical standards.
