HR series data sheet - .PDF file.

Relec Electronics has been awarded Network Rail approval for the HR series of DC/DC converters. The HR series are versatile power supplies that are suitable for use in transportation and other advanced electronics systems, particularly railway applications.

Typical train-borne applications include: cab CCTV systems; on-board Wi-Fi for passengers; electronically controlled washroom facilities; GSM-R train radios for driver-to-control-centre communication. Track-side applications include: level-crossing monitoring; train location systems; and passenger information systems.

The DC/DC converters have a wide input range of 12VDC to 168VDC and a configurable output.

They can be operated from all common DC traction supplies of 24V, 36V, 48V, 72V, 96V, 110V and 120V nominal voltage. The converters comply with EN51055 and EN50121-3-2, IEC/EN 60950-1, IEC61000-4-2, -3, -4, -5, and -6.

The HR2320-9RG is Network Rail-approved; its certificate number is PA05/05958 and its catalogue number 086/034203.

Relec Electronics

At Relec Electronics the philosophy is to help design engineers build better solutions.

At Relec Electronics the philosophy is to help design engineers build better solutions.

We are proud to have one of the most comprehensive power supply ranges available, for both DC to DC and AC to DC applications. In addition, we offer a range of complementing products including EMC filters, switches and displays. Our aim is to build partnerships with customers and suppliers to both understand their requirements and to ensure a reliable supply of robust, yet technically advanced components that can be relied upon in the long term.

Power supplies, circuit protection and interface products form the backbone of our business. We work very hard to bring high-quality competitive products to the market, and our customers can be assured that any product we are promoting will not have reached them without full dialogue with the supplier together with a personal factory audit.

We believe the future is to offer our clients more choice thereby ‘adding value’ to their projects. This is achieved by offering custom products in all the lines we supply and by offering manufacturing services such as sub-assemblies and finished products. In our UK warehouse, we hold significant stocks of both standard and customer-specific parts and offer all the commercial services you would expect, including JIT, KANBAN, and specialist agreements tailored to suit individual customer needs.

Relec’s sales and technical support personnel, including our QA department, are all qualified engineers and are committed to ensuring that all aspects of our service meet and exceed today’s high expectations. We pride ourselves on providing extensive technical support for design engineers and full commercial support for our customers. By working with a limited number of manufacturers, who are leaders in their various technologies, Relec can provide the best solutions available.
