Our journey began in 1964 with Power Development Ltd manufacturing non-linear resistors in Silicon Carbide (SiC). As consumer demands and technology moved rapidly on, Power Development Ltd led the way in developing a range of Metal Oxide Varistors (MOV), and in 1976 became the only MOV manufacturer in the UK. A claim that we still hold to this day.

Advances in materials and processes mean that we continually assess, refine and develop the performance capability of our MOVs. In turn, this means that we have been able to design and manufacture an exceptional range of products, both off the shelf and bespoke, to provide a solution to the effects of transient overvoltage in any application or industry.

Our technical team provide advice and support to consultants, design engineers and contractors on projects of all types and sizes, be that developing surge protection solutions to suit bespoke applications, analysing electrical schematic drawings or conducting site surveys to specify SPDs, or talking through product wiring details with installers.

In-house design engineers, state-of-the-art manufacturing and our own independently accredited (ISO 17025) test laboratory mean that we have the capability to design, test and manufacture from prototype to production seamlessly, efficiently and cost-effectively.

With representation on BSI and industry standards committees, we ensure that we are not only up-to-date, but are influential by sharing our expertise, in the development of standards, guidelines and regulations.

PD Devices provides 1-to-1 and group training, face to face or via virtual platforms. This might be project/product specific training tailored to suit your requirements, or CPD training to provide a better understanding of the causes of transient overvoltage and to discover how to correctly design a surge protection solution to mitigate the potential damage that may cause.
