Eaton Marine Solutions - TechnologyThe harsh environmental conditions and the critical nature of the protected equipment set special dependability requirements for marine UPSs.
All Eaton marine UPSs are designed to meet the most stringent industry standards. The double-conversion online topology with a static bypass switch is Eaton’s choice for marine use. This protects against all types of power disturbances that may occur in the supplying network and is the only topology that meets the highest performance class, VFI-SS-111, requirements. All Eaton UPSs are tested and certified to meet appropriate safety and EMC standards.
Eaton UPSs are built into one cabinet that houses all the electronics: the rectifier, the inverter, the static bypass and the microprocessor control. This configuration allows the entire system to be controlled as on integral device, and leads to higher reliability when compared to using separate power converters. It also saves plenty of valuable space.

The most critical loads may require increased protection. Therefore all 3-phase systems can be connected to parallel redundant configuration.
In such a system two or more UPSs are supplying and sharing the same load. Should a failure occur in any of the UPS units, the faulty unit is automatically disconnected from the load and the remaining unit or units continue to supply the load. This redundancy leads to extremely high system level reliability.
System performance monitoring is often crucial for continuous operation. Therefore a versatile combination of remote communication options via serial communication ports and potential free contacts are available.
