MegaLine 7500/2

The Legrand UPS MegaLine 7500/2 model is a UPS using high

frequency PWM technology, On Line Double Conversion type,

solid neutral, modular architecture, with the possibility of N+X

redundant configuration, Rated Power 7.5 kVA – 5.25 kW,

equipped with valve-regulated hermetic-type accumulator batteries,

contained inside the UPS in a specific compartment or in one or more

external cabinets, sized to guarantee a minimum autonomy of 11

minutes when 80% charged.

1.1 Modularity

The MegaLine UPS has a modular architecture, it is composed

of identical modules that, conceptually operating in parallel, compose

the power section (1250VA power modules) and the group

of accumulators (battery modules) of the UPS.

These modules are contained inside the UPS and have identical

functions.

The power modules are composed of the functional blocks listed

below:

• Rectifier/PFC

• Inverter

• Booster

• BatteryCharger

The battery modules on the other hand, are composed of a series

of batteries, protected accordingly by fuses in series.

1.2 Expandability

The modularity of the UPS allows for power and/or back-up time

expansion, upgrading on site, without the need for calibration, settings,

factory changes and in any case without the use of dedicated tools.

1.3 Redundancy

The modular UPS is configurable as an N+X redundant power system,

with 1,250 VA power modules, contained in the UPS cabinet, with

suitable mechanical latches and dedicated and pre-arranged electric

connections.

Redundancy is achieved by an architecture based on the concept

of “load sharing”.

1.4 Architecture

The system uses distributed parallel architecture, in other words all

of the power modules share the load (load sharing) so that none

of the power modules remain inactive or in stand-by, thus ensuring total

continuity to the power supply of the loads, even in case of failure

(with suitable redundant sizing). The modular architecture offers

the possibility of supplying the load with energy even if the inverter

of a power module shuts down (if there are two or more modules).

The rated power that can be delivered by the sum of the working

modules will always be available to the user who can operate at a

reduced load or, with a redundant configuration, at the normal load.

1.5 Bypass

A by-pass circuit automatically transfers the load directly to the

primary network without interrupting the power supply, in conditions

of overload, overheating, continuous voltage outside of the tolerances

and inverter fault.

A diagnostic and shutdown software, if installed accordingly on a PC

connected to the UPS, allows you to access all of the MegaLine

operating data, regulate and set

special functions (such as the display screen) and control the shut

down of Windows and Linux operating systems.

An optional software (UPS SuperviSor) provides hierarchical

multiserver shutdown and remote UPS management for any operating

system in a heterogeneous network (Windows, Novell, Linux and the

most common Unix).

MegaLine is managed by a microprocessor and is capable of

displaying measurements, alarms and operating

modes with a liquid crystal control panel

and high luminosity signals.

The UPS is capable of carrying out the following measurements and

displaying the values directly on the display:
