Modular UPS

ProstarM is a leading modular UPS manufacturer in India. Modular UPS system is popular across many business sectors because it is flexible, easy to scale, and provides better redundancy than some other UPS models. Due to this design feature, data centres deploy a number of high-capacity modular UPS systems to achieve N+1 redundancy. Modular UPS solutions tend to be near autonomous systems. All of their critical components are distributed between individual units and there are no single points of failure present in these UPS systems.

Modular UPS solutions from ProstarM come with a wide range of input voltage and hot swappable operation for all modules. This feature cuts the repair time of the UPS system and reduces its maintenance costs. Hot Swappable design also means that the UPS solutions make power reconfiguration easy for businesses as their requirement change over time. Modular UPS system is easy to install, upgrade and reconfigure, saving considerable time and costs for businesses.

Factors to consider when choosing modular UPS systems


For the most efficient performance, modular UPS should be as close as possible to their rated capacity. A load with lower capacity will lead to a drop in the efficiency of modular UPS system. The liberty to scale the UPS solutions up or down as per need enables users to maintain the load close to rated capacity of the modular UPS system.

Working conditions

Modular UPS solutions are not designed to perform in harsh and rugged conditions. These UPS solutions lack transformers and are best used in clean work environments.


Modular UPS solutions tend to be quite flexible in terms of options for batteries. However, the work conditions factors sighted above should also be considered when choosing batteries for the UPS system. Modular UPS systems could utilize a number of enclosed battery modules that are comprised of smaller amp hour batteries, or the UPS system could allow larger batteries such as the lithium ion batteries which are also offered by ProstarM.
