A UPS system includes a power distribution assembly having a plurality of side faces and comprising an AC input and an AC output and at least two UPS assemblies having respective side faces confronting respective ones of the side faces of the power distribution assembly, each of the at least two UPS assemblies comprising a plurality of converter modules and an interconnection module configured to switchably couple AC inputs and AC outputs of the converter modules to respective ones of the AC input and the AC output of the power distribution assembly through conductors passing through the confronting side faces. The conductors may couple the power distribution assembly to the at least two UPS modules without the use of conduit and/or cable trays.

UPS systems with modular block architectures

A power supply apparatus includes an uninterruptible power supply (UPS) having an input configured to be coupled to a first power source and an output configured to be coupled to a load and a first static switch configured to provide a switchable bypass path from the first power source to the load. The apparatus further includes a second static switch controllable to provide a switchable path between the load and a second power source, and a controller circuit configured to cooperatively control the first and second static switches to transfer the load to the second power source. The controller circuit may be operative to transition the load from a first state wherein the load receives power from the first power source via the first static switch to a second state wherein the load receives power from the second power source while isolated from the first power source.
