A UPS Group Synchroniser (UGS) synchronises the outputs from two separate groups of parallel UPS which may be supplied from separate ac sources. It enables the outputs from the groups to be configured into a dual bus format.

The UPS maintains synchronisation between the outputs of the parallel groups, regardless of input supply variations. For example, one group may be on battery power or standby power and theother powered by the mains power supply. The device can be generally used with up to eight UPS modules between two separate groups.

The addition of a Static Transfer Switch (STS) on the output enables the protected load to be supplied from either of the parallel groups. In this configuration, if one of the UPS groups fails, the STS can transfer the load to the second group - providing there is spare capacity.

Designed by Riello UPS the UGS is ideal for use with Master Plus UPS within data centre environments who are looking for high resilience and power continuity.
