4.2 OPERATION MODES
4.2.1 Normal VFI Operation Mode (Voltage Frequency Independent)
Under normal conditions the Load is
permanently powered by the
Inverter with
constant amplitude and frequency
.
The
Rectifier, powered by the Utility, 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
Utility 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
Utility Power is available,
the
Load is normally powered through the
Automatic Bypass
.
When the
Utility Voltage is detected out of the
prescribed tolerances, the
Load is
automatically transferred to the
Inverter.
When the
Utility recovers, the Load returns to
the
Automatic Bypass after a variable time
defined by the control unit.
Fig. 4.2.2-1 Block diagram eBoost™ Operation Mode
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
Utility 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 6.4
/ eBoost).
NOTE !
The eBoost™ Operation Mode is available only if enabled at the factory or by a GE
GLOBAL SERVICES FIELD ENGINEER.
