GENERAL DESCRIPTION

The LP 33U Series Uninterruptible Power Supply (UPS) provides the energy supply for critical loads
which need a reliable, continuous, and free from 'voltage disturbances and frequency fluctuations'
supply.
In case the utility 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 utility recovers.
LP 33U 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 33U Series can be configured, if chosen, for the ECO Mode permitting the maximum
energy saving.
The main typical performances of the LP 33U 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 <10%.
•
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, 65 dB (A) (50 & 60 kVA) to avoid noise to the persons operating in the
same environment.
•
Multi-language LCD screen.
•
Total battery management: SBM (Superior Battery Management)
•
High battery capacity, 9 minutes (50 kVA) and 8 minutes (60 kVA), with battery housed in the
UPS cabinet.
•
Wide rectifier input voltage tolerance: 177 - 229 VAC (Line-Line).
•
Wide rectifier input frequency tolerance: +/-10% (54 - 66 for 60 Hz).
•
RPA (Redundant Parallel Architecture) up to 4 units.
•
GE Connectivity.
•
Compliance with UL standard 1778.
