DMS technologies understands that today’s market requires more than just power system suppliers. Successful organisations require partners to fully understand their power requirements and provide solutions that combine electrical, physical and financial demands.

Panel Mount Stand-Alone Power Supplies

Our 100D and 220D are stand-alone, convection cooled power supplies designed to be panel mounted and used by control panel manufacturers and utility companies to provide a reliable power source. These 100W and 220W power supplies are available in 12V, 24V and 48V as standard and for special requirements can be modified to provide different outputs such as 36V. As they are microprocessor controlled they can be programmed to provide a multitude of additional outputs including auxiliary power and a range of indicators and alarms. A range of protection features protects the unit from damage whilst also optimising battery life through continuous monitoring and deep discharge protection. Both models have a wide input voltage range as standard and offer an MTBF of over 20 years.

These compact power supplies offer an idea stand-alone solution for locations such as control panels and equipment cabinets. They offer a cost effective, reliable power output at a range of voltages and can be used with or without battery backup with optional temperature compensation if required.

Higher Power Requirements

Alongside the 100W and 200W units described there are also available high power rated modules ranging up to hundreds of Amps. There are both standalone as well as modular solutions with a range of voltage outputs and alarm functionality. With products designed and manufactured in the UK even if there is not a matching product within the range an adaptation can often be made to meet a users requirements.

This strong heritage in designing and manufacturing power supplies has now been extended to launch a new and innovative Impressed Current Cathodic Protection system. This has a number of unique advantages over older thyristor based designs including higher power density, higher MTBF figures, built-in programmable interrupters and potential measurements log.

Battery Power

We have been the Value Added Distributor for Enersys in the UK and Ireland for nearly 30 years and are also the UK importer for the US made Lifeline batteries. Within the lead acid market we maintain close relationships with Exide, Haze and Yuasa, whilst we also have our own brand of Red Flash AGM batteries that offer very high performance characteristics relative to cost. We have links with a range of lithium and NiMH manufacturers including Tadiran, Panasonic, GP Batteries and A123 as well as with the emerging Far East factories. We started life as a battery pack manufacturer and we remain the leading UK pack builder. We are set up to provide both standard batteries and also more bespoke, high quality battery packs where applications such as Oil & Gas or Rail require them.

Our Facilities

Our purpose built 18,000sq ft manufacturing and assembly facility in Romsey, Hampshire features both long run and small production lines. This allows us to meet demands ranging from small quantity prototype products to full project roll out schedules totalling hundreds of systems. Our dedicated test and development section keeps us at the forefront of evaluating new technologies and designs whilst allowing us to provide real life performance data for our products. Our extensive warehouse facility gives us the ability to react quickly to meet urgent demands for standard product or meet strict call off order schedules to match our customers’ own build programs.
