Power solutions made for marine and subsea applications

We provide a wide range of durable, rugged and efficient power supplies and product solutions to meet harsh shipboard environmental requirements, such as extreme temperatures, shock and vibration. We work closely with our partners in the marine sector, often operating as their very own power design department, ensuring they continue to power their applications with pioneering, precise and efficient power. We’re also best placed to provide a great deal of flexibility, designing completely bespoke power systems within short lead times.
