Three Phase UPS System with Modular, Hot-Plug Design
Classification the ENERTRONIC modular UPS
in accordance with EN/IEC 62040-3
Beside high availability, UPS systems have guarantee high SS: The output waveform sinusoidal with all linear and
power quality.
VFI: The output voltage independent all mains voltage
and frequency variations.
111: The dynamic deviation the output voltage will not
exceed the three tolerance curves the standard
EN/IEC 62040-3 :
• the operating mode changes
• during linear load steps
• during non-linear loadsteps

According this topology four Tier levels (I-IV)
are used:
Tier Non-redundant
Tier II: Basic redundant
Tier III: Concurrently maintainable (No shutdowns for
equipment replacement and maintenance)
Tier IV: Fault tolerant (Withstands single unplanned
event). Frequency variations sporadic f\JJ\
