450W Power Supply Unit for Subsea Equipment

Power Supply Unit for Subsea Equipment Keeping the distances between circuit cards constant despite high input voltages was the main challenge in this project. These products are extremely reliable – they have to be, because we need them to work for years at a time in the deep sea without maintenance service. This power supply unit can be modified and customized to specific requirements! Just contact us – we design, develop and manufacture power supply solutions for all branches of industry and virtually any application!
