DUAL BUS SYSTEM
The Dual Bus System powers the
priority loads from two independent
sources.
This configuration increases the
redundancy and availability level of a
multi-module configuration. Each bus
may consist of a single module or up to
8 modules in parallel, kept in synchro
by the UGS (UPS Group Synchroniser).
DYNAMIC DUAL BUS SYSTEM
Two independent systems set in Dual
Bus Configuration can be merged
together at any time for system
expansion or maintenance thanks to
the PSJ (Parallel System Joiner) option.
This provides a lot of flexibility in your
installation in case of maintenance or
when it is necessary to change the
redundancy level of both systems.
