Master MPS series UPS devices ensure maximum protection and
power quality for any type of load, especially for mission
critical applications, security systems and electro-medical
equipment, industrial processes and telecommunications.
Master Plus is an on-line double conversion UPS (class VFI SS
**1 in accordance with IEC EN ******3) with a transformer
isolated inverter.
EASY SOURCE
Master MPS makes powering UPS devices by power generators and
MV/LV transformers easier and more efficient, reducing loss
in systems and coils and correcting the power factor and
eliminating harmonics by the loads powered by the UPS
itself.
In addition to this, the progressive start-up of the
rectifier and the possibility of reducing the recharge
current of the batteries, allow for the containment of the
current absorbed and therefore do not overload the
source, especially when the source is a generator.
BATTERY CARE SYSTEM: MAXIMUM BATTERY
CARE
Normally the batteries are kept charged by the rectifier;
when mains power fails, the UPS uses this energy source to
power its utilities. Therefore, proper battery care is
critical to ensuring correct UPS operation in emergency
conditions.
Battery Care System consists of a series of features and
capabilities that allow for battery management in order to
obtain the best performance possible and extend their
operating life.
• Dual level charging regime to optimize recharge currents
and reduce charge times
• Temperature compensation and deep discharge protection to
reduce overall battery ageing
• Charge blocking system to reduce electrolyte consumption
and lengthen the life of VRLA batteries
• Battery tests to diagnose, in advance, any reduction in
performance or problems with the batteries.
Master MPS is also compatible with different battery
technologies: vented open lead acid, VRLA AGM and NiCd.
FLEXIBILITY
Master MPS is suited to all types of applications, from
computers to the most demanding industrial environments.
Thanks to the broad range of accessories and options, complex
architectures and configurations can be created to ensure
maximum power to critical loads:
expansions (in redundancy or power) may be made in
already-operating parallel systems, even without having to
switch off any UPS that are already operating and thus,
maintaining power to utilities.
UGS and PSJ devices also ensure redundancy in the downstream
distribution of the parallel system, creating a “selective”
system that provides power to other connected utilities even
when there are failures on one utility.
MAXIMUM RELIABILITY AND AVAILABILITY
Distributed or centralised parallel up to 8 units per
redundant (N*1) or powerparallel. A parallel between models
with different power levels is possible. Maximum levels of
availability also in the event of an interruption to the
parallel bus cable: the system is “FAULT TOLERANT”.
It is not affected by connection cable faults and continues
powering the load without a continuity solution, signalling
the anomaly with an alarm.
OPTIONS
• UGS - UPS Group Synchroniser Allows 2 or more non-parallel
UPS devices to remain synchronised even during mains
power failure. The UGS also enables a Riello UPS to be
synchronised with another power source that is independent
and of a different power rating.
• PSJ - Parallel Systems Joiner Connects two UPS groups in
parallel, hot (without output discontinuity) through a
power
coupling switch. A UPS group (slave) is is permanently
synchronised to the Master group both when the mains supply
is present or not present (thanks to the UGS synchronising
device) . If there is a failure on one of the UPS devices in
parallel, it is cut-off. The PSJ will automatically connect
the remaining UPS to the other group in parallel via an
external bypass, in order to ensure the redundancy of the
load.
EASE OF INSTALLATION
Master MPS requires only a very small space for installation
(only 0.*4 sqm for a **0KVA system); in addition, front
access allows servicing of all major components from the
front panel, making side access unnecessary. Given the
upwards ventilation, Master Plus can be placed up against a
wall, reducing the space to be left free, necessary in event
the flow of hot air coming out the rear.
