UPS Function The uninterruptible power supply (UPS) is connected between the consumer's critical equipment (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 blackout it will supply the load for a predetermined time (autonomy time). In addition, the UPS provides the following advantages in comparison with conven- tional supply systems (mains, motor generator sets, etc.):
Better Output Power Characteristics The UPS output voltage control of frequency and amplitude guar- antees consistent and stabilised output power. Mains voltage fluctuations and frequency changes that are usually present in electricity supply systems do not affect the UPS output voltage.
Uncoupling from Mains Distortion By using double energy conversion from ac to dc and back to ac and using an isolation transformer in the inverter output, all mains distortions are filtered out. Therefore, all loads connected to the UPS system are protected against mains disturbances that can be present in industrial electricity supply systems. This is especially important for sensitive electronic devices, e.g. computer systems, control systems, medical equipment.
Complete Protection against During long term or short term ac mains supply interruption, the Mains Failures UPS system guarantees continuous supply to the connected loads
by means of a battery. The battery is connected to the rectifier output and the inverter input of the UPS system. In normal opera- tion the inverter (which feeds the load) is fed by the rectifier. In case of a mains failure, the connected battery automatically feeds the inverter. Thus the load is supplied without interruption. How- ever, the load can only be supplied by the battery for a certain time (autonomy time, see chapter 1.4 "Battery"). 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
This is a class A product.
In a domestic environment, this product may cause radio interference, in which case, the user may be required to take additional measures.
