OPERATION MODES

4.2.1 Normal VFI Operation Mode (Voltage Frequency Independent)

Under normal conditions
permanently powered by the inverter with
constant amplitude and frequency.
The Rectifier, powered by the Mains, supplies
the inverter and the battery-charger keeps the
battery fully charged.
The inverter converts the DC voltage in a new
AC sine wave voltage with constant amplitude
and frequency independently from the input
Mains Power.
4.2.2 eBoost™ Operation Mode (option)
eBoost™
e High efficiency (up to 99%)
Boost Fast power transfer (< 2ms)
When the eBoost™ Operation Mode is
selected, and the Mains Power is available,
the Load is normally powered through the
Automatic Bypass.
When the Mains Voltage is detected out of
the prescribed tolerances, the Load is
automatically transferred to the Inverter.
When the Mains recovers, the Load returns to
the Automatic Bypass after a variable time
defined by the control unit.
The eBoost™ Operation Mode can be used for single units or the RPA Parallel System, for up to 6 UPS
modules, with all units individually able to supply power through a redundant communication bus.
The eBoost™ Operation Mode can be configured directly by the user for higher efficiency, considering
the Mains reliability and criticality of the Load.
The selection between the two operation modes "VFI mode and eBoost™ Operation Mode", or switching
between operation modes at required time, can be done through the UPS control panel (see Section 7.4
/ eBoost).
NOTE !
The eBoost™ Operation Mode is available only if enabled at the factory or by a GE
GLOBAL SERVICES FIELD ENGINEER.
