Reliable Power Solutions Built for Marine and Offshore Environments

In the demanding marine industry, reliable power solutions are essential — and that’s where Control Transformer excels. With decades of experience, we design custom-engineered transformers that meet the strict requirements of marine and offshore applications.

Our products, including transformers for remote operating vehicles (ROV) systems, power distribution units (PDUs) and motor drives for marine propulsion and deepwater exploration, are built to perform in harsh environments while maintaining high efficiency and durability. We can offer IECEx/ATEX certification on a case-by-case basis (includes additional non-recurring engineering fees), ensuring compliance with the toughest safety and quality regulations.

Our commitment to quality and adherence to rigorous ANSI standards ensures every marine product meets the industry’s highest benchmarks for reliability — with a failure rate of less than 1%. Each power system is purpose-built to withstand the challenges of marine environments, providing dependable power to sustain your operations in the toughest conditions.

From compact designs that fit into tight spaces to rugged transformers built to withstand saltwater corrosion and vibration, our solutions are tailored to meet your specific needs. Whether it’s deck-side power distribution or specialized ROV magnetics, Control Transformer delivers the performance and reliability your marine operations demand.
