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 1.
•
Input current THD 8%.
•
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.
•

•
High battery capacity, 25 minutes (10 kVA) and 10 minutes (20 and 30 kVA), with battery housed
in the UPS cabinet.
•
Wide rectifier input voltage tolerance: 324 ÷ 478 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 50091-2.
