Information applies to all models unlessotherwise specified.2.1 Principles of OperationThe NetPro 19” UPS stores electric energy in batteries housed in the unit. This allows the UPS to supply outputpower even when the incoming mains power is cut off completely. Energy is stored as Direct Current (DC), whileinput and output energy are Alternating Current (AC) in sine wave form. Therefore the UPS contains an inputconverter (AC to DC) and an output converter (DC to AC) (See fig.1).The NetPro 19” UPS is a SECOND GENERATION On-Line UPS with:* a capacitor bank in the DC line* battery not in line with the DC link, resulting in:- enhanced battery life- optimal battery charging* full wave input converter with power factor correction* extremely wide input voltage and input frequency tolerance* no inrush current at start up2.2 Normal ConditionsUnder normal input conditions (see section 4.2) energy from the mains is channeled through the input converter,which supplies the output converter and, together with the battery charger, keeps the battery fully charged.Surges and spikes are blocked completely at the input converter and very instable mains can be supported. Theoutput converter synthesizes a completely new AC output sine wave to supply the load (electrical equipment).Figure 1 Block diagram of the NetPro 19” UPS, mains presentOUTPUT:PERFECT UPS POWERINPUT:MAINS POWER WITH DISTURBANCESOUTPUTCONVERTERINPUTCONVERTEROPTIONALFROMMAINSRFIFILTERCardConnectINTERFACEPROGR.
