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 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.

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.

4 DESCRIPTION

4.1 BLOCK DIAGRAM AND MAIN ELEMENTS DESCRIPTION

Fig. 4.1-1 UPS block diagram

The Uninterruptible Power Supply System LP33 Series 80 & 100 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 graphical LCD
screen, displaying the operation modes, the measurements and the events / alarms.

Rectifier

The rectifier converts the 3-phase mains voltage into a controlled and regulated DC-voltage, in order to
supply power to the booster, and to charge the battery through the battery-charger.

Inverter

The inverter converts the DC voltage into a three-phase AC-voltage with constant amplitude and
frequency, which is completely independent from the AC-input voltage.

Automatic Bypass

The automatic bypass consists of a static semiconductor-switch (SSR: Static Switch Relay), used to
provide an uninterrupted transfer of the load from inverter to mains when operating in VFI Mode.
If ECO Mode is enabled, the Static Switch Module (SSM) will transfer load from utility to inverter in case
the utility power anomaly.

Back-Feed Protection

All LP33 Series UPS’s are equipped with an automatic system for the protection against voltage back
feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1).
This protection works automatically by opening contactor K6 (in series with the thyristors of the static
switch) and eventually K7, and acts in case of internal defects of the system, or due to incorrect
operation of the maintenance bypass Q2.

Manual Bypass

The manual bypass consists of a pair of manual switches Q1 and Q2, which allow the isolation of the
UPS from the load, while still supplying the load with power directly from the mains.

Battery

The battery, normally charged by the battery-charger, supplies the DC energy to inverter in the event
of mains failure.

Modifications reserved Page 13/66

OPM_LPS_3UO_80K_M10_1US_V010.doc User Manual LP33 Series 80 & 100 UL S1

4.2 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. 4.2-1 Energy flow in VFI Mode operation

The inverter converts the DC voltage in a new AC sine wave voltage with constant amplitude and
frequency independently from the input mains power.

ECO Mode operation

When the ECO Mode is selected, and the mains
power is available, the load is normally powered
through the automatic bypass.

When the mains voltage is detected out of the
prescribed tolerances, the load is automatically
transferred to the inverter.

When the mains recovers, the load returns to the
automatic bypass after a variable time defined
by the control unit.

Fig. 4.2-2 Energy flow in ECO Mode operation

The ECO Mode can be configured directly by the user for higher efficiency, considering the mains
reliability and criticality of the load.

The selection between the two operation modes “VFI Mode and ECO Mode”, or switching between
operation modes at required time, can be done through the UPS control panel (see Section 7.1.3).

In case of parallel system

ECO Mode cannot be enabled for RPA Parallel System.

Attention: A single unit equipped with a RPA - Parallel board, must be considered as parallel, thus

disabling ECO Mode.

Modifications reserved Page 14/66

OPM_LPS_3UO_80K_M10_1US_V010.doc User Manual LP33 Series 80 & 100 UL S1

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. 4.2-3 Energy flow in automatic bypass operation

When the inverter recovers, the load will be re-transferred automatically to the inverter.

In case of parallel system

Each unit has its own bypass.

All the bypasses in the system work together, their control being managed in the same manner by
all units.

The units are continuously exchanging information before taking such decision.
In case the inverter of one unit fails, its bypass remains operating.
It is excluded only if the unit is separated from the common bus by opening its output switch Q1.

Mains recovery operation

As soon as the mains recovers, the rectifier
starts up automatically supplying the inverter
and the battery-charger recharges the battery.

In case the inverter has been shut down
following a complete discharge of the battery,
when the mains recovers the system start up
automatically.

Fig. 4.2-4 Energy flow at mains recovery operation

When the energy stored in the battery is sufficient to ensure a minimum time of operation with the
actual load, in case of a future mains failure, the load will be retransferred to inverter (if selected VFI
Mode).

In case of parallel system

When the AC input power recovers, the rectifiers will start up sequentially according to their
number in the parallel system in order to avoid an initial inrush current.

The inverters will start up automatically, but only when the battery has recharged enough for a

minimum runtime with the present load.
When enough inverters to supply the load have been restarted, the load will be transferred from the

automatic bypass back to the inverter bus-bars.

Modifications reserved Page 15/66

OPM_LPS_3UO_80K_M10_1US_V010.doc User Manual LP33 Series 80 & 100 UL S1

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.

Fig. 4.2-5 Energy flow in manual bypass operation

Mains failure operation

In the event of a mains power failure, the
rectifier and the battery-charger turns OFF,

while the inverter continues to supply the load
without interruption using the energy stored in
the battery.

During the battery discharge, the graphical LCD
screen displays the remaining autonomy
runtime, based on the battery capacity and the
applied load.

Fig. 4.2-6 Energy flow during mains failure operation

In the event of an extended mains failure, before the battery is fully discharged, the alarm “stop
operation” warns the user that the UPS will start the shutdown procedures when the indicated time

expired (normally 3 minutes).

In case of parallel system

With parallel system for power capacity:

• With the bypass mains power available as the warning “battery low” occurs on one unit, after

timeout (selectable) the load is transferred to mains.

• With missing bypass mains power as the warning occurs on one unit, the system starts the

timeout (selectable) of “Stop operation” and then the output load shuts down.

With redundant parallel system:

• As the warning battery low occurs on one unit unnecessary to support the present load, after
timeout (selectable) this unit shuts down and the load is shared between the other units.
As the warning occurs on one unit necessary to support the present load, the system starts the
timeout (selectable) of “stop operation” and then the output load shuts down.

OPM_LPS_3UO_80K_M10_1US_V010.doc User Manual LP33 Series 80 & 100 UL S1

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 LP33 Series 80 & 100 connected on the same bus, which ensure the highest reliability rate and
increase the power availability.

Parallel system for power capacity

Two or more units can be paralleled in
order to achieve output power superior
to the maximum power delivered by a
single UPS unit.
The maximum total load shared
between the n parallel units can
achieve the 100% of the installed
nominal power system.
In the event of one unit fails, the load
will be suddenly transferred to the
mains by the bypass.

Parallel system for redundancy

The parallel system can be defined
redundant only in case the nominal
power rating of n-1 units of n parallel
units is sufficient to supply the required
load power.

Fig. 4.3-1 RPA system diagram

The load in a parallel redundant system, is equally shared by n units connected on the output bars.
Should one of the parallel units trip off-line, the remaining (n-1) units will share the load maintaining the
applications protected by inverter until the normal situation restores.

Load sharing between parallel units
The control bus exchanging the data between the microprocessors of the paralleled units provide for a

constant proportional load sharing in every load condition.

Management and synchronization of the parallel system
All the units are identical without master and slave relationship.

One unit is arbitrarily selected as the reference (the first unit connected on power bus) being this unit the
first synchronized with the mains voltage, and all the other units synchronize with the first one.
In case the reference unit fails or it is excluded from the parallel power bus any other unit will take over
the reference role.
The AC input power source of all the bypasses must be the same for all the units of the parallel system
excluding any phase shift between them.

Control bus of the parallel system
A high-speed serial bus, guarantees communication, synchronization and load sharing between the

UPS modules.
Each module controls it’s own function, while the Master (each unit can be Master) controls and
commands the status of the system.

NOTE !

The parallel system excludes more rectifiers connected on common battery.
No transformers, fuses or automatic circuit breakers should be inserted between
the unit’s output and the load common bus bars.

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. 4.4-1), the sharing circuit
between the individual UPS is integrated in the communication bus of the system in order to assure an
equal sharing of the Rectifiers output currents.

Pay attention to the following recommendations:

• The units delivered for this functioning mode need a special parameter setting, so they must be
prepared in advance before the installation.

• The installation must be performed only with the UPS system completely shut down.

• The AC Rectifiers input power (5) must be the same, with clockwise phase rotation for each unit.

• Each Rectifier must be set for the same floating DC voltage and the same Battery current limitation.

• It is mandatory to install the fuses / MCB (7) on each line connecting the Rectifiers to the common

Battery for maintenance / safety reasons (see Section 4.7.2).

• In case a unit must be powered down for maintenance, switch-OFF the concerned unit before
opening the DC fuses / MCB on the Battery line (7).

• If an emergency generator set supplies the UPS, and the free contact “Generator ON” is connected
to the Customer Interface, connect a separate NO free contact on each parallel unit.

• Do not connect the temperature sensor for automatic battery floating voltage compensation.

• Do not enable the function Boost charge.
