Modular UPS architecture (or topology) is a method
designed to reduce cost and give UPS users flexibility in system configuration
and use. Modular UPS systems consist of fixed control and power switching
modules. Typical systems are designed to fit into one rack. Larger UPS
systems are designed for large IT installations span
multiple racks and consists of dozens to hundreds of modules.
This modular
UPS system must have the following structured requirements:
l Performance: The ability
to provide stable supplies despite possible changes in the electric grid caused
by problems of voltage, frequency and waveform characterized by networks and
complex power lines, and of course providing the steady energy required to
supply in all load conditions including power over surge, surge power
fluctuations and the absence of grid power supply from independent batteries
during disaster recovery. Performance
has minimum specification requirements including demands arising from the
quality of system, such as: efficiency, floor space, volume, weight, and
acoustic noise. Among other performance gains it’s possible to point
achievement to the power density that enables receiving high power in small
floor space. And the technology achievements are reflected in software,
hardware, heat transfer, mechanical packaging and of course nice and easy
access and high-level Human Engineering. The system contains parallel modules
that allow the power distribution of current flow according to the number of modules
at the entrance, exit and battery loading, so there is an equal loading on each
module.
l Reliability and availability: of power supply the demand for
which has grown to require the availability of “six nines” that
is 0.999999. Reliability is required despite the dynamics resulting from the
networks and frequently changing loads and sometimes unpredictable behavior.
The Highest reliability is used in Double Conversion True Online work
meaning batteries that are connected to the regular exit and input converter
with no transition downtime during power outages.
l Green energy: received by high
efficiency means improved technology and precise
planning. Current efficiency UPS systems now exceed
the 95% which means only 5%
of losses, versus previous generation systems whose
efficiency was around 90-92%.
l Redundancy: Redundancy
is required from your UPS unit so that a single fault will allow work to
continue without a hitch. Redundancy is possible by parallel systems work.
Modular UPS System Advantages:
l
Can grow
with power as required and as a
result minimal expense of purchase. Of course this is
a savings of working hours and physical
labor required and upgrading the device.
l
Possibility
to replace a faulty module without disturbing. Compared
with normal system repair which requires disabling as when
replacing a module, the system continues to
function without disabling at all.
l
Opportunity to
receive redundancy in a simple
and immediate manner as any failure by one of
the N Modules still allows regular supply load. Work
method and N+ allows a dramatic increase
in reliability since
it allows an additional module error before the
system collapses.
l
Work on increasing
the energy efficiency (for increased system efficiency maximum load while
working with normal redundancy system where each system load is 50% at maximum
efficiency and with little supply wastage).
l
Elegance - a
more modern and elegant modular system, flexible operation and
of course all the important parameters. The system is
equipped with advanced control and management panels.
Benefits of the Modular UPS
Manufacturers invested a lot of effort to show case the
positive aspects of the product. These include:
l
Reliability: Reliability is one of the most crucial demands from the UPS. Even clients
who want to save money and are prepared to settle for a third grade system,
will still search for the promise of as high a MTBF as they can find. What is
reliability when it comes to the UPS? Continuous provision of power to the
load. The objective is to keep the system running on inverter even in case of a
fault. Without transferring to bypass like it would in a common system.
l
Size and Weight: As far as weight and size are concerned, there is a big advantage
to a system without transformers and power chokes. The smaller and lighter the
system the cheaper the shipment and storage are. Furthermore, if the client is
interested in a redundant UPS, a modular system with one extra module will be
at least twice as small as two regular parallel redundant UPS systems.
l
Efficiency: Since modular systems are inevitably without transformers, one can reach
the highest efficiency possible – up to 95%.
l
Repair time and
spare parts: The common consensus is that technicians prefer to work with
systems that are made up of modules. Most repairs can be done by replacing the
module. When it comes to modular systems the MTTR is low, spare parts are
available and similar in different systems. These advantages are very
meaningful to distributors.
In Conclusion
Even though much more can be said on this topic, the
emphasis here is clear: Modular UPS systems have many benefits over the
standard ones, starting from the basics regarding reliability and efficiency
and up to the benefits of size and weight.
