Custom Units

The ETPS team has many years of experience in modifying programmable power and test systems. Our bespoke solutions can help you engineer the impossible.

Custom units are ideal for high end complex projects, helping you research and explore new and unproven areas of technology. We can often design a system to match your exact test specifications using one of our standard AC or DC products as a basis. Technology power platforms such as linear, switch mode and motor driven can all be modified on request.

High value projects often involve difficult engineering challenges, which is why our team uses a hands-on approach to provide specialist knowledge and technical support along the way. Working alongside you, your customers and manufacturing partners, we can overcome design challenges to create a completely bespoke unit.

Our team's access to magnetic, metal and PCB fabrications along with EMI, EMC and temperature test facilities mean we can take care of any changes in specification fast. CAD and simulation software means you can visualise your system before we create it.

If your unit will be used in harsh environments, we can modify the electrical and mechanical components to protect them from conditions such as shock, vibration and humidity. That way, we ensure every system is compliant with even the most stringent standards, such as NATO’s STANAG. We can even build your system into a wheeled flight case so it can be easily and quickly moved around the site.
