    DESCRIPTION PRINCIPAL DIAGRAM AND MAIN ELEMENTS DESCRIPTION Fig. 3.1-1 UPS principal diagram The Uninterruptible Power Supply System LP 33 / 10 - 20 - 30 kVA can be divided into the following main elements: Electronics The UPS is designed with a microprocessor–controlled supervision and diagnostic system. Communication between user and UPS is achieved by the front panel consisting of an LCD screen, displaying the operation modes, the measurements and the events / alarms.

  • Page 12: Operation Modes

    OPERATION MODES This section describes the different possible operation modes of the UPS explaining the function of the main modules of the UPS. On-line mode operation Under normal conditions load permanently powered by the inverter with constant amplitude and frequency. The rectifier, powered by the mains, supplies the inverter and the battery-charger keeps the battery fully charged.
  • Page 13 Automatic bypass operation In On-line operation mode, the load is permanently supplied by the inverter but, in case of trouble on the inverter, or when overload or short-circuit on the output occur, if the mains voltage do not exceed the admitted tolerances, the load is instantly transferred to the mains through the automatic bypass, taking advantage of the higher short circuit...
  • Page 14 Manual bypass operation The manual bypass circuit consisting of Q1 and Q2 manual switches, permits the transfer of the load directly to the mains without interruption, leaving the UPS galvanically separated from the output load. This type of operation is normally used when the UPS system must be completely turned off for maintenance or reparation.
