The system level static bypass in the Eaton 93PM G2 UPS cabinet determines the attainable output
power of the UPS. The static bypass line consists of static switch, a back feed protection isolation device
and fuses designed to protect the static switch. The back feed protection and bypass fuses are located in
series with the static switch. In addition, there is a system level control unit that constantly monitors the
power delivered through the bypass line or to the input of the UPS. Transfers to static bypass are
seamless and performed automatically by the system as needed, for example, in case of an extended
system overload.
Each UPM includes a rectifier, DC/DC converter, inverter and independent controls. Each UPM is able to
operate and share the load independently, despite the status of the other UPMs.
If utility power is interrupted or falls outside the parameters specified in Section
the UPS uses a DC supply (i.e. battery, super capacitor, etc.) to maintain power to the critical load for a
specified period of time or until the utility power returns. For extended power outages, the UPS allows you
to either transfer to an alternative power system (such as a generator) or shut down your critical load in an
orderly manner.
