UPS Paralleling with Eaton Hot Sync Technology

Field-tested and installed in thousands of installations around the world, Eaton Hot Sync technology continunes to be the global reliability standard.

UPS Paralleling with Eaton Hot Sync technology

This technology enables a multi-module configuration to operate in parallel without the need for inter-module communications. This eliminates the system level single point of failure inherent in traditional parallel configurations and maximizes availability.

Hot Sync redundant

Hot Sync redundant allows N+x parallel installation of up to eight Eaton UPSs, with the UPS modules sharing the critical load between them. Should a failure of any kind occur with either module, the critical load remains 100% UPS protected. Internal diagnostics immediately isolate the faulty UPS module from the critical bus while the other UPS assumes the full load.

Hot Sync capacity

Hot Sync capacity enables up to eight UPS modules to operate in parallel to increase the load capacity. By adding more UPS modules than are needed to support the load, redundancy can also be achieved. For example, should the load requirement be 2000 kW, selecting three 1000 kW units would give N+1 redundancy--two modules to feed the load and one for redundancy
