UPS configurationAdvantages - 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 timeTransformer 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 bridgesTransformer 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)

IGBT technology for clean input Pure Pulse® configuration for highest input performances

UPS input performances Total Current Harmonic Distortion

THDi=2% @ 100% load and 5% @ 50% load

UPS input power factor: 0.99

Constant behavior at all loads Negligible harmonics contents at full
