2 INTRODUCTION 2.1 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 Uninterr

3 DESCRIPTION 3.1 BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION Fig. 3.1-1 UPS block diagram The Uninterruptible Power Supply System LP 33 Series / 30 & 40 kVA can be divided into the following main elements: Electronics The UPS is designed with a microprocessor–controlled supervision and diagnostic system. Communication between user and UPS is achieved by the front panel consisting of an LCD screen, displaying the operation modes, the measurements and the events / alarms.

3.2 OPERATION MODES This section describes the different possible operation modes of the UPS explaining the function of the main modules of the UPS. VFI (Voltage Frequency Independent) Mode operation Under normal conditions the load is permanently powered by the inverter with constant amplitude and frequency. The rectifier, powered by the mains, supplies the inverter and the battery-charger keeps the battery fully charged. Fig. 3.2-1 Energy flow in VFI Mode operation T

Automatic bypass operation In VFI (Voltage Frequency Independent) operation mode, the load is permanently supplied by the inverter but, in case of trouble on the inverter, or when overload or short-circuit on the output occur, if the mains voltage do not exceed the admitted tolerances, the load is instantly transferred to the mains through the automatic bypass, taking advantage of the higher short circuit power. Fig. 3.2-3 Energy flow in automatic bypass operation When the inv
Summary of the content on the page No. 13
Manual bypass operation The manual bypass circuit consisting of Q1 and Q2 manual switches, permits the transfer of the load directly to the mains without interruption, leaving the UPS galvanically separated from the output load. This type of operation is normally used when the UPS system must be completely turned off for maintenance or reparation. Fig. 3.2-5 Energy flow in manual bypass operation Mains failure operation In the event of a mains power failure, the rec

3.3 RPA PARALLEL SYSTEM The RPA (Redundant Parallel Architecture) allows to extend the unit to a parallel system with 2, 3, or 4 units LP 33 Series connected on the same bus, which ensure the highest reliability rate and increase the power availability. Parallel system for power capacity UTILITY INPUT Two or more units can be paralleled in order to achieve output power superior to the maximum F1 F2 F3 F4 LPS33U_030-040_RPA system_GE_01 power delivered by a single UPS unit.

3.4 UPS PARALLELED ON THE SAME BATTERY NOTE ! 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. In case of parallel units running with a Common Battery (max. 4 UPS - see Fig. 3.4-1), the sharing circuit between the individual UPS is integrated in the commu
