Operation Manual - Critical Power Supplies

USEDESCRIPTIONThe purpose of a UPS is to ensure a perfect power supply voltage for the devices connected to it irrespective of whether mainspower is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a stableamplitude and frequency, irrespective of the changes and/or variations occurring on the electricity network. For as long as theUPS receives energy from the mains, the batteries are kept charged under the control of the multiprocessor board. This boardalso controls continuously the amplitude and frequency of the mains voltage, the amplitude and frequency of the voltagegenerated by the inverter, the load applied, the internal temperature and the state of efficiency of the batteries.The block diagram below shows each of the parts that make up the UPS.Block diagram of the UPSIMPORTANT: Our UPS are designed and produced for long life even under the severest conditions. Remember however thatthey are electrical power equipment items and as such are in need of periodic checks. Besides, some components have a lifecycle of their own and must therefore be checked at regular intervals and may need to be replaced, where due to the conditions:in particular, the batteries, fans and in some cases the electrolytic capacitors.It is recommended to implement a preventive maintenance program, using manufacturer authorised and trained servicepersonnel.Our Technical Servicing department is at your disposal to discuss the different personalized preventive maintenance optionswith you.
