Over 40 years of Excellence
E Preston has been a specialist distributor of electrical and electronic components since 1980, offering thousands of products to meet a wide variety of needs and applications.
But we do more than simply sell components – we have built a reputation as a company who does business the traditional and honest way. Paying attention to the simple things – like phoning people back when we say we will – has kept our customers coming back for over four decades.
Our staff are experts in their fields, we maintain appropriate stock levels, and all of our processes are fully computerised to ensure a smooth operation.
We also understand that business is carried out between people, not companies. We do the hard work to maintain relationships with our suppliers as well as our customers. That way everybody in every part of the supply chain is satisfied – from the manufacturer to the end customer.
The SPPVR family of surge protection devices (SPDs) is our answer to the growing need for safe and reliable photovoltaic (PV) installations in residential and commercial buildings.
Powerful protection is the first step to ensuring a long lifetime for your equipment and inverters: these SPDs ensure that your system will not be damaged by any overvoltage event on the direct current (DC) side of your PV application.
The SPPVR products can be deployed in residential settings, for example in small combiner boxes or commercial applications such as array protection boxes in PV fields. SPPVR offers a future-proof portfolio for all possible use cases.

E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.
Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.
