Intersystem Synchronization Unit System (ISU System)

The ISU system consists of inter-connected ISUs. One ISU system may consist of up to 5 ISUs, regardles of ISU configuration. The ISU system synchronizes the voltage of parallel operation systems running in battery operation.

The ISU system may also include one or more external synchronization sources, e.g. a gen-set or a non-APC Silcon UPS system.

Synchronization accuracy of the ISU is better than 2o.

Intersystem Synchronization Unit (ISU)

The ISU is an active part of an ISU system, serving as the interface to the sources and the ISU system.

The ISU can be connected to a parallel UPS configuration, using the standard parallel communication controller in the parallel operation system.

(See Intersystem Synchronization Unit User’s Manual for further details.)
