Why to Use and Why to Avoid Using Modular UPS Systems


Modular UPS systems are lately gaining momentum because of an attractive idea of answering power protection desires as you grow. The concept permits to boom UPS capability or redundancy while wished, by means of small, light-weight, compact, hot swappable, low cost modules, without allocating extra ground area. The merits come but with positive flaws, the object considers each.

The modular UPS method has the following blessings over Standard UPS answers:

1.Lowest ground area.

Most modern-day Three Phase UPS structures have scaling ability, which enables to feature extra devices in parallel gadgets for extra energy or redundancy. Modular systems are based totally on a rack type enclosure that dc power supplies includes battery cupboard at its bottom, and small mild weight swappable modules placed one above the alternative, which can be introduced on every occasion wanted. This vertical scaling technique takes about 25% of ground space, compared to traditional UPS devices with the same overall power capacity.

2. Highest Power Availability.

Availability of UPS system is defined as the percentage of the time that conditioned strength is to be had. If a UPS would in no way fail, its availability might be 100%. Unfortunately UPS systems or its backup batteries do fail, and during restore time no conditioned energy is to be had to guard the weight. The modular method permits to lower the repair time to 3 hours needed for a technician to reach and change the defective module, in comparison typically to 24 hours or extra for a carrier engineer to arrive and fix the device.

Three. Higher efficiencies.

UPS performance reaches its most stage while the weight is at its maximum score. The capability to increment UPS strength by using including small modules when wanted, while maintaining high ratio of general load to total UPS ability, renders the most efficient solution.

4. Lowest possibility of UPS failure at some stage in renovation.

Reviews suggest that 30% of UPS screw ups are caused by human mistakes all through UPS repair or upkeep. The modular approach enables to update and isolate on site the faulty module, that’s sent to the provider center for restore, diminishing the possibility of UPS failure in the course of carrier.

The modular UPS technique has the subsequent dangers over Standard UPS answers:

1. Limited Output strength.

A modular technique calls for enormously high amount of small, mild weight parallel electricity modules. Most UPS structures are based totally on modules, which can be dealt with by using a single individual, located in a 19 inch Rack. For extra power, manufacturers advise to feature extra Racks in parallel. The possibility of failure while extra modules are linked reduces the Availability benefit. In addition, the nuisance and high maintenance expenses may also increase while number of module goes up, making the modular technique unpractical for structures exceeding four to five modules in parallel.

2. High Single Point of Failure (SOP) Probability.

Unlike traditional stand alone UPS structures, each equipped with all of the wished UPS function blocks. A unmarried failure in certain purposeful components, if common to all modules inside the rack, along with common Battery bank, Transfer transfer, Control and Display units, may additionally cause overall output failure.

3. Higher Initial Investment.

Generally, initial installation of a modular UPS includes the Rack and all not unusual additives. This funding may additionally but be compensated in future due to higher performance and reduced running prices, as well as because of decreased financing prices related to the Grow as you Go approach, which the Modular UPS structure offers.

Conclusion In end, Modular UPS method isn’t the excellent option to all scalable UPS wishes, however it should be notion over as a part of a popular UPS method. In addition, on the way to see the complete picture, selection of a modular technique calls for thorough knowledge of the particular UPS layout consisting of exact facts about common objects, no longer constantly provided by using UPS manufacturers.
