Powerware Marine Solutions - Technology

All Powerware UPSs for marine applications 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 topology protects against all types of power disturbances that may occur in the supplying network and it is the only topology that meets the highest performance class, VFI-SS-111, requirements.

All Powerware UPSs are tested and certified to meet the appropriate safety and EMC standards.

Powerware 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 one integral device. This leads to higher reliability than 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.
