General Description
The uninterruptible power supply (UPS) is connected between the consumer’s equipment or installations (the load) and supply mains. Its function is to guarantee a continuous and conditioned power supply to the load. Even in the case of a total black-out it will supply the load for a predetermined time (autonomy time). In addition, the UPS provides the following advantages in comparison with conventional supply systems (mains, motor generator sets, etc.). UPS can provide a stable voltage and stable frequency, clean, high-quality power to the load.
During long term or short term ac mains supply interruption, the UPS system guarantees continuous load supply by means of a battery. The battery is connected to the rectifier and the inverter of the UPS system. In normal operation the inverter (which feeds the load) is fed by the rectifier. In case of a mains failure, the battery feeds the inverter. Thus the load is supplied without interruption. However, the load can only be supplied by the battery for a certain time. If longer autonomy times are required, we recommend the use of a Diesel Generator Set. In this case the battery autonomy time only has to be sufficient for the time span between mains failure and full operating capacity of the Diesel-Generator-Set.
