Our technical capabilities

Complete end-to-end power supply solution support

Standard engineering and support services – with a large power development team, The Power Supply Technology Centre provides a core set of engineering services to support power supply design, integration, compliance, and long-term production. Our teams collaborate across the wider Technology Network to solve complex design challenges and deliver fully integrated, application-ready power solutions.

Engineering consultation

We provide expert, application-focused consultation to help you define electrical, mechanical, and environmental requirements at the earliest stage.

This includes evaluating constraints such as space, thermal limits, compliance targets, and system architecture. Our engineers work closely with your team to identify the most suitable approach—whether standard, configurable, modified, or fully custom—ensuring the optimal balance of performance, cost, and time-to-market.

Partnerships & benchmarking

Through close collaboration with leading power supply manufacturers, we offer access to a broad and proven portfolio of technologies. We provide benchmarking and comparative analysis, enabling you to assess multiple solutions against your specific performance, efficiency, and integration requirements.

This ensures you select the most appropriate platform before committing to design or modification work.

Design capabilities

Our in-house engineering teams deliver electronic, magnetic, and mechanical design to create or optimise power solutions. This includes schematic and PCB design, custom magnetics development, and mechanical packaging tailored to your application.

We focus on improving efficiency, reducing thermal stress, increasing power density, and ensuring seamless physical integration within your system.

System integration

We develop complete, ready-to-integrate power systems by combining power modules with additional functionality such as EMC filtering, protection circuits, sequencing, monitoring, and control interfaces.

This system-level approach reduces your design complexity, shortens development time, and ensures reliable operation within the wider application environment.

Compliance support

We provide hands-on guidance to help you meet EMC and safety compliance requirements, reducing risk and accelerating certification.

Our in-house pre-compliance testing, including thermal and EMC verification in dedicated facilities – identifies potential issues early in the design cycle, minimising costly redesigns and delays during formal approval processes.

Advanced testing & measurement facilities

Our dedicated laboratories are equipped with state-of-the-art measurement and validation equipment, including EMC chambers, thermal imaging systems, climate chambers, and high-power test setups.

These facilities support rigorous development, prototyping, and validation, ensuring your power solution performs reliably under real-world operating conditions.

Flexible production

We support manufacturing both internally and through trusted European production partners, enabling flexible production volumes, from rapid prototyping and small series runs to full-scale production.

Our in-house prototyping capabilities, including SMT lines and fast turnaround, help accelerate development timelines while ensuring a secure and stable supply chain.. Our own DC/DC R series benefits from a stable supply chain.

Lifecycle management

We help provide proactive lifecycle support, including component monitoring, obsolescence management, and long-term supply planning.

By tracking component availability and managing safety stock strategies, we help ensure continuity of supply and reduce risk over the lifetime of your product- particularly important for long-life or regulated applications.
