  • 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.
  • Page 12: Operating Status

    OMD94016 REV. C OPERATING STATUS The UPS has four different operating modes, as described below: Normal operation • Bypass operation • Battery operation • Manual bypass • 3.3.1 NORMAL OPERATION During normal operation all of the circuit breakers/isolators are closed, except for MBCB (maintenance bypass).
  • Page 13: Bypass Operation

    OMD94016 REV. 3.3.2 BYPASS OPERATION The load can be switched to bypass either automatically or manually. The manual changeover is due to the BYPASS SWITCH which forces the load to bypass. In case of failure of the bypass line, the load is switched back to inverter without interruption.
  • Page 14: Manual Bypass

    OMD94016 REV. C The system restart from the black-out condition can be customized based on the requirements of the plant, in three different modes: Bypass: loads are supplied as soon as the bypass line is available • (factory configuration). Inverter: loads are supplied by the inverter (even if the bypass line •...
  • Page 15: Figure 5: Manual Bypass

    OMD94016 REV. FOLLOW THE PROCEDURES CONTAINED IN THE MANUAL The sequence of manual bypass switching and return must be carried out with respect to the procedure indicated in the installation and start-up section. The manufacturer cannot accept responsibility for damage arising from incorrect operation.
