3  INTRODUCTION 

 
 

3.1  GENERAL DESCRIPTION 

 

The 

LP33 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 u

tility 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. 

 
 

 

LP33 Series

 is a truly 

VFI

 double conversion 

Uninterruptible Power Supply

 (UPS), 

equipped with 

automatic bypass

, where the 

load

 is normally supplied by the 

inverter

 

 

 

LP33 Series

 can be configured for 

ECO Mode

 permitting high operating efficiency.

 

 
 
 

The main typical performances of the 

LP33 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 (option). 

• 

ECO Mode

 operation. 

• 

Compact designed for commercial applications. 

• 

Low level acoustic sound, 68 dB (A). 

• 

Multi-language graphical LCD screen. 

• 

Total battery management: 

SBM

 (Superior Battery Management) 

• 

High battery capacity extendable in several battery cabinet configurations. 

• 

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. 

• 

Compliance with UL standard 1778 and CSA C22.2.
