Mil-COTS Power Supplies

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.

Technology Development

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.

Power Supply Design

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.

Build to Print

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.
