MASTER PLUS
BATTERY CARE SYSTEM: MAXIMUM LIFETIME POTENTIAL
Traditionally, when a mains supply is present the UPS charges
its batteries. Battery power is used for the inverter should the
input supply fail. Efficient battery management and care is
therefore essential to the overall performance of the UPS in an
emergency. The Master Plus Battery Care System consists of a
range of features designed to provide optimum performance
and enhanced operating life:
- Dual level charging regime to optimise recharge currents and
lower recharge times
- Temperature compensation and deep discharge protection to
reduce overall battery aging
- Charge blocking system to reduce electrolyte consumption
and lengthen the life of VRLA batteries
- Predictive battery testing to spot potential battery deterioration
and failure
Master Plus is also compatible with different battery technologies:
open-vase lead acid and AGM and Gel VRLA, NiCd.
FLEXIBILITY
Master Plus is suitable for a wide range of applications including
IT and the most demanding industrial environments. With a
broad range of accessories and options, complex configurations
and system architectures can be achieved to guarantee
maximum power availability and the option to add new UPS
without interruption to existing users.
Using the Riello UPS Group Synchroniser (USG) and Parallel
Systems Joiner (PSJ) sophisticated inter group parallel and
redundant systems can be achieved to provide the highest
possible levels of resilience and availability.
EASE OF INSTALLATION
Master Plus is compact with a foot print of only 0.64sqm for
a 200kVA system. Front access to internal assemblies and top
panel ventilation make space allocation within confined data
processing or plant rooms easy. Master Plus can be placed
against a wall as there is no requirement for rear or side panel
access for maintenance or ventilation.
