  • Page 118 UPS user manual GENERAL UPS DESCRIPTION UPSaver is a completely adaptable multi-functional, high-efficiency structured system for the protection of the energy supply. The system flexibility is achieved by using hot-swappable power modules in order to easily expand the system power up to 1600 kVA. The UPSaver power modules uses 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 output voltage.
  • Page 119 UPS user manual POWER MODULE (BPU) The power module, part of the UPSaver UPS, is composed of the following main sections:  rectifier / battery-charger;  inverter;  battery static switch;  inverter and bypass static switches. Picture 2 – Power module (BPU) block diagram The power module is not provided with isolator switches, which are all installed in the distribution columns of the I/O module.
  • Page 120 UPS user manual 3.1.3 Battery static switch The battery static switch consists of two diode-SCR couples connected in anti-parallel, one for each polarity, and allows to control the connection and disconnection of the battery to the DC bus, in order to reduce the losses and optimize the battery expected lifetime. 3.1.4 Bypass static switch The Static Bypass allows to transfer the load between Inverter and Emergency Mains, and vice-versa, in a very short time, and uses SCR’s as power commutation elements.

  • Page 124 UPS user manual The AC loads are directly supplied from the inverter output, that is the parallel of the inverters of the single power modules (BPU). When the Green Conversion algorithm is active the rectifier operates at reduced DC voltage and supplied the inverter alone, since the battery is disconnected from the DC bus.
  • Page 125 UPS user manual Picture 13 – Battery discharging In case the supply is restored before the battery is completely discharged, the system will be switched back to normal operation automatically. In the opposite case, the inverter shuts down and the load is switched to the bypass line (bypass operation). If the bypass line is not available or is out of tolerance, the loads supply is interrupted as soon as the battery reaches the discharge limit threshold (black-out).
