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.

The concept referred to as a triport of a utility-interactive UPS (uninterruptible power supply) is explained. It has a simple and cost-effective structure and enables a low-cost UPS to be designed with all required UPS features, particularly for single-phase UPSs in the 1-10 kVA power range. The different features in comparison to traditional UPSs are briefly discussed, e.g. voltage and frequency tolerance and utility failures. Results and experience with field operation are illustrated by oscillograms and diagrams.<<ETX>>
