  • Page 11: Introduction

    INTRODUCTION 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.

  • Page 12: Description

    DESCRIPTION BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION Fig. 4.1-1 UPS block diagram The Uninterruptible Power Supply System LP 33U Series / 50 & 60 kVA can be divided into the following main elements: Electronics The UPS is designed with a microprocessor–controlled supervision and diagnostic system.

  • Page 16: Rpa Parallel System

    4.3 RPA PARALLEL SYSTEM The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3, or 4 units LP 33U Series connected on the same bus, which ensure the highest reliability rate and increase the power availability.

  • Page 17: Ups Paralleled On The Same Battery

    A parallel system with a Common Battery for two or more UPS, requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a qualified GE engineer. Usually each UPS Unit runs with its own Battery.
