MegaLine 3750
The Legrand UPS MegaLine 3750 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 3,750 VA – 2,625 W,
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
accumulator batteries (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 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. GENERAL FEATURES
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:
