Relec Electronics is offering its UP series switched-mode power supplies (SMPSs), which deliver from 150W to 400W (UP350 = 300W, UP500 = 400W) with free air convection (UP350 = 350W, UP500 =500W with fan cooling) and are housed in a low-profile U channel.

Built using 105°C electrolytic capacitors for a long service life, the units are designed for a range of telecommunication and industrial applications requiring low maintenance and noise.

All of the models have universal AC input and are available with a single output voltage of 12VDC, 15VDC, 24VDC or 48VDC. Safeguards include short-circuit protection, over-voltage protection, overload protection and over-temperature protection.

The 350W and 500W units also feature active inrush current limiting, remote voltage sensing, remote inhibit function and a power OK signal.

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.
