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” Inverter DC Battery bank AC AC DC static bypass Rectifier Backfeed contactor Input mains Load preventing feedback to the mains from the inverter in case of mains failure and a fault in the bypass circuit 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

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 )
