  5. UPS configurationDouble conversion with inverter output isolation transformer Q2 MANUAL BYPASS SSM AUTOMATIC BYPASS K6 INPUT MAINS RECTIFIER INVERTER Q1 CB4 LOADS K7 INVERTER TRANSFORMER BATTERY CB3 • Double conversion(VFI) technology with output isolation transformer • Automatic bypass for overloads, short circuit and UPS disturbances conditions • Manual bypass for UPS maintenance operations without load interruption • Protection safety devices integrated - back feed protection K6 standard - battery disconnect CB3 standard

  6. Backfeed protection IEC 62040-1 : ……“For fixed installation UPS, backfeed protection may be provided internally or externally to the UPS in the a.c. input line” Backfeed contactor static bypass Input mains Rectifier Inverter AC Load DC DC AC Battery bank Standard feature inside UPS cabinet • No additional cost required • No addition installation required Fully compliant with IEC 62040-1 • Compliance to UPS installation safety requirements Safer operating condition • Safer operation for end users and service engineers preventing feedback to the mains from the inverter in case of mains failure and a fault in the bypass circuit

  7. UPS configuration Advantages - Output Isolation Transformer • No DC component in output (galvanic isolation by transformer) Transformer less UPS – DC components are controlled electronically • Lower DC voltage – less number of batteries per string (30-32 blocks) Less cost for same type of batteries and back up time Transformer less UPS – More battery blocks, connections etc • Better short circuit capability in battery mode (bypass not available) Transformer based UPS – 2.7 X Nominal current Ph-Ph - 4 X Nominal current Ph-N / G Transformer less UPS – 2.2 X Nominal current • No neutral current back to the mains in case of unbalanced load in Double conversion mode • Better management of unbalanced load. A Zig-Zag transformer will share an unbalanced load on the three inverter bridges Transformer less UPS – inverter legs may see unbalanced load ( different leg operates at different load % - Components stress level are different) improves battery lifetime through less ripple • Better management of non linear load (low level harmonics are short-circuited)
