Page 9: General Ups Description
OMD94016 REV. 3. GENERAL UPS DESCRIPTION The UPS systems of the AEG HE line use IGBT technology with a high changeover frequency in order to allow a low distortion of the current re- injected into the supply line, as well as high quality and stability of the output voltage. -
Page 10: System Description
OMD94016 REV. C SYSTEM DESCRIPTION 3.2.1 RECTIFIER It converts the three-phase voltage of the AC mains into continuous DC voltage. It uses a three-phase fully-controlled IGBT bridge with a low harmonic absorption. The control electronics use a 32 bit µP of latest generation that allows reduction of the distortion of the current absorbed by mains (THDi) to less than 5 %. -
Page 11: Battery And Battery Charger
OMD94016 REV. 3.2.3 BATTERY AND BATTERY CHARGER The battery can be installed inside or outside the UPS. The battery charger logic is completely integrated in the rectifier’s control electronics. The battery is charged, according to the DIN 41773 Standard, every time it has been partially or completely discharged. -
