Monitoring and diagnostics for UPS systems

Hartmut Dipl.-Ing. Gaul; Stenio Lingaya; Hermann Mickal

A description is given of a monitoring and diagnostics system for UPS systems. The process data of the individual units are acquired and condensed by local computers. These data are transmitted via a serial bus to a central PC which displays them in the form of a block diagram and, in the event of a fault, analyses the cause of the trouble.
