We know how to build power systems with optimal efficiencyUK Defence Power Solutions
Our four pillars best describe how we partner with our clients, including: Power Supply Design and Build to Print, Technology Development and Mil Cots Power Supplies.
Serving defence, aerospace and marine sectors, we deliver robust, UK-designed systems that excel in harsh environments. Partner with us for power solutions that align with your operational demands, backed by rigorously testing and award winning solutions, with accredited certification.
Avanta is a division of On-systems, also based in the UK and specialising in robust military power supplies. Made for durability and efficiency, the power units support operations across land, air and sea environments. Working closely with defence companies, Avanta delivers bespoke power solutions that meet international standards. Using cutting-edge technology and decades of experience, the highly reliable power supplies as used in military applications worldwide.
Some of the key factors driving MIL technology development include precise power input quality and output control for non-standard voltage requirements. We develop technology that complies with MIL-STD electromagnetic standards, together with harsh environment resilience.The power integrations we develop focus on reliability and performance. When required we partner with suppliers who are versed in the complexities MIL standards bring, helping us to provide long-term success in mission-critical applications.
On-systems delivers exceptional custom power supply design services for aerospace, defence and marine sectors. Our experienced UK-based engineering team specialises in creating bespoke power solutions that meet the most demanding technical requirements. We transform complex power challenges into efficient and reliable systems through innovative design, rigorous testing and cutting-edge technology. With multiple industry awards and a commitment to excellence, we provide tailored power solutions that enhance operational performance and reliability across high-stakes environments.
Assembling in-house has become more complex, expensive and less practical, we work with clients to improve efficiency and quality, through outsourcing their build to print to us. Our experience in manufacturing electrical components from drawings, has given us the knowledge to deliver high quality products from customers designs. This has led to repeating contracts from Aerospace and Defence manufacturers.
Integrated Power Engineering & Manufacturing Services
Our Power Services Include Power Supply Design and Build to Print, Technology Development and Mil-COTS power supplies (Avanta).
We integrate our power systems with your defence hardware, enabling manufacturing efficiency across critical platforms. Protecting our people, information and society requires power supply systems that are built to be resilient regardless of usage, such as in harsh environments across land, sea and air.
We aim to implement systems that simply go unnoticed, a result of the reliability a rigorously tested and well-designed power infrastructure provides.
Protection for our world. Through our partnershipswe design and power the systems that keep us safe.
By collaborating with our customers and partners, we manufacture reliable bespoke power supplies and systems that integrate with hardware that helps protect our way of life. Our solutions are rigorously tested, not only in our test facilities, but also in harsh real world environments.

What does On-Systems do?
On-Systems designs and manufactures advanced power conversions and management systems for intense environments. Our work at On-Systems covers bespoke AC-DC and DC-DC converters, battery chargers and fully integrated power subsystems, which are used in the defence, aerospace and industrial sectors, where performance and reliability are essential. Each product is engineered to deliver high efficiency within compact lightweight casings built to operate under tough mechanical and thermal conditions.
What makes On-Systems' products different from standard power supplies?
Each design begins with considering the environment. Units are built for vibration, shock, temperature extremes and electromagnetic compatibility. Unlike typical mass-market power supplies, solutions are customisable, with protection and redundancy features outlined by user specifications. This approach ensures performance consistency over long service lives while simplifying maintenance. The result is highly efficient, low-size, low-weight power hardware optimised for complex or harsh operating settings.
How does On-Systems support customers from design through deployment?
On-Systems supports customers throughout the full product lifecycle, from early requirements discovery and specification to prototyping, testing and authentication. Our team works together closely to ensure the solution fits performance, safety, environmental needs and can assist with documentation and integration guidance. After deployment, we continue to provide responsive technical support to help maintain reliability and address changes over time.
Which industries rely on On-Systems technology?
On-Systems serves clients from a range of industries such as aerospace, defence, marine and transport. Projects usually include mission-critical applications such as radar, communications and power distribution on land, sea and air platforms. Designs meet strict military and commercial standards, while remaining adaptable for civilian use. By combining engineering with architecture, On-Systems meets the needs of organisations where assured power delivery can affect safety and operational capability.
Can On-Systems create a custom power solution for unique requirements?
Yes. On-Systems has in-house design, simulation and test facilities, allowing for full custom development from concept to qualification. Our engineers work with clients to translate electrical, mechanical and environmental criteria into a validated, manufacturable design. From adapting existing converters or producing a brand-new subsystem, On-Systems focuses on shortening lead times, while withholding reliability.
