Operating Manual
LP 33 Series 60-80-100-120 kVA / S2
3 INTRODUCTION
3.1 GENERAL DESCRIPTION
The
LP 33 Series
Uninterruptible Power Supply
(UPS) provides the energy supply for critical loads which
need a reliable, continuous free from voltage disturbances and frequency fluctuations supply.
In case the
mains fails
, or it exceeds the permitted tolerances, the energy to supply the
load
is furnished
by the
battery
with a backup time dependent on its capacity, until the mains recovers.
LP 33 Series
is a truly
VFI
double conversion
Uninterruptible Power Supply
(UPS),
equipped with
automatic bypass
, where the
load
is normally supplied by the
inverter
.
LP 33 Series
can be configured, if chosen, for the
ECO Mode
permitting the
maximum energy saving.
The main typical performances of the
LP 33 Series
system are the following:
•
VFI (Voltage Frequency Independent) double conversion technology to provide an excellent
quality power supply.
•
Input power factor 0.98.
•
Input current THD: Active IGBT Rectifier:
<9%
Active IGBT Rectifier - Clean Input Module: <4.5% (<3.5% at 75% load)
•
Automatic bypass and manual bypass to improve reliability and maintenance.
•
Microprocessor controlled supervision.
•
Dual AC inputs (optional).
•
ECO Mode operation.
•
Compact and agreeable design expressly conceived for “Office environment”.
•
Low level acoustic sound, to avoid noise to the persons operating in the same environment.
•
Multi-language LCD screen.
•
Total battery management: SBM (Superior Battery Management)
•
Wide rectifier input voltage tolerance: 323 ÷ 460 Vac (phase - phase).
•
Wide rectifier input frequency tolerance: +/-10% (45 ÷ 55 for 50 Hz and 54 ÷ 66 for 60 Hz).
•
RPA (Redundant Parallel Architecture) up to 4 units.
•
GE Connectivity.
•
Compliance with European standard IEC 62040.
