HR series data sheet - .PDF file.

The HR series of DC/DC converters are versatile power supplies that are suitable for use in transportation and other advanced electronic systems. The extremely wide input range of 12–168VDC and configurable output provides a single-unit system for a range of applications.

HR series of DC/DC converters

Its key features include high efficiency, high reliability, low output noise, and excellent dynamic response to load/line changes.

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

The output is configurable as 12VDC, ±12VDC or 24VDC; LED indicators display the status of the converter and allow for visual monitoring of the system at any time.

The converters may either be plugged into a 19in rack system according to IEC60297-3, or be chassis mounted. Cooling plates are available for conduction-cooled applications or heatsinks for convection cooling.

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.
