- 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.
