1 UPS AEEEMBLY 1.1 Features This equipment complies to EN62040-2/IEC62040-2 standard CE. UPS FUNCTION The Uninterruptible power system (UPS) is connected between the user’s equipment or load and mains supply. Its function is to guarantee a continuous and conditioned power supply to the critical load. Even in the case of a total black-out it will supply the load for a predetermined time. -
Page 5: Rectifier/Discharger
1.3 Rectifier/Discharger The rectifier is a converter that converts ac voltage to dc voltage. The rectifier is connected to mains via the filter chokes which reduce the mains distortion created by the rectifier. The PFC is included in rectifier to reduce input current harmonic, increase input PF to be near 1 and boost voltage to be DC bus voltage. -
Page 6: Static Bypass
logic, T-type 3-level topology, assure a very low output voltage distortion (see "Technical Data" section). The inverter control logic restricts the maximum output current to 150% of the nominal current in case of a short circuit. In case of overload (up to 150% linear load of the nominal current), the output voltage is kept constant. -
Page 7: Manual Bypass
1.7 Manual Bypass The manual bypass function is to supply power directly to the connected load during UPS system failure or maintenance. The bypass consists essentially of one switch. With this series UPS systems, commutation from different operating modes to manual bypass will take place without interruption. With the maintenance bypass on, the power supply system may be completely switched off, thus permitting maintenance of power modules and bypass modules to be carried out safely (if cabinet need to be maintained external maintenance bypass is required to disconnect all power in cabinet). -
