Eaton 9PHD Marine UPS is a reliable and efficient, state of the art UPS solution that can be configured for a range of marine & offshore applications. It brings the benefits of modern, modular, IGBT based UPS technology to the shipborne environment providing the lowest Total Cost of Ownership in its power range.

  • Topology: Online (IGBT)
  • Power Rating: 30 - 200 kW
  • Efficiency: 97%


An unexpected loss of power in critical marine & offshore applications can result in anything from an economic setback or physical damage, or in the worst case, to the loss of lives. Reliability is the number one requirement for a marine UPS. The Eaton 9PHD Marine UPS ensures the reliable supply of uninterrupted clean power to keep your critical load up and running no matter what. Reliability equals safety.


UPS reliability is essential for the continuation of operations, and so too is financial performance. High efficiency (up to 97% on double conversion mode) means less energy burned to heat and a reduction in energy used for cooling. This means lower costs and lower emissions. The Eaton 9PHD Marine UPS efficiency brings savings in money, weight, space and for the environment.


Whatever the changing conditions – and however quickly they change – the Eaton 9PHD Marine UPS is designed to maintain a steady, uninterrupted, clean power supply. This market-leading resiliency is the result of the number of advanced technologies built-in to the Eaton 9PHD UPS. With a wide range of optional add-on features, the unit is built to meet the specific and demanding requirements on land and at sea.
