Operating Manual

LP 33 Series 60-80-100-120 kVA / S2

4 DESCRIPTION

4.1 PRINCIPAL DIAGRAM AND MAIN ELEMENTS DESCRIPTION

Fig. 4.1-1 UPS principal diagram

The Uninterruptible Power Supply System

LP 33 Series

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.

Rectifier – Active IGBT Rectifier

The

Active IGBT Rectifier

converts the 3-phase mains voltage into a controlled and regulated DC-voltage,

supplying the

inverter

and to charge the

battery

through the

battery-charger

Thanks to modulation strategy applied to

IGBT bridge

, the

rectifier

provides clean input power in terms

of low

THDi

and unity power factor. For this purpose the UPS’s are offered in two configurations

depending on the required harmonic content (THDi):

- Active IGBT Rectifier
- Active IGBT Rectifier - Clean Input Module

Both configurations provide clean input current at full and partial loads, avoiding thus possible
interference with other upstream equipment.

Inverter

The

inverter

converts the DC voltage into a three-phase sinusoidal 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

mains

when operating in

VFI

(

Voltage

Frequency Independent)

Mode

If chosen the

ECO Mode

, the SSM transfer the

load

from

mains

inverter

in case the utility fails.

Back-Feed Protection

All

LP 33 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

, and acts in case of internal defects of the system, or due to wrong

manipulations on the

maintenance bypass Q2

Manual Bypass

The

manual bypass

consists of a pair of manual switches

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 stored by the

battery-charger

, supplies the DC energy to

inverter

in the event of

mains

failure.
