2.1GENERAL 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 0.8.

•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, 50 dB(A) (10 kVA), 55 dB(A) (20 kVA) and 61 dB (A) (30 & 40 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, 22 minutes (10 kVA), 9 minutes (20 kVA), 29 minutes (30 kVA) and 19 minutes (40 kVA), with battery housed in the UPS cabinet.

•Wide rectifier input voltage tolerance: 152 ÷ 240 VAC (phase – phase).

•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.
