What is Modular UPS?
Aug 21, 2019

The modular UPS can be its own self-contained system. It is essentially a combination of battery and power modules that are within the same cabinet or chassis. These modules are building blocks that typically share a common frame, buss, and communicate either through either a main logic controller or, in some units, by the logic built into each module.


Why to choose modular UPS?

There can be several advantages to using a modular UPS configuration:

1) Ability to grow capacity on an as-needed basis.

2) Hot-swappable design of modules allows faster repair time and reduced maintenance cost.

3) The efficient modular UPS adopted in data centers consume less power and require less cooling effort, thus enhancing power savings and equipment efficiency.

4) Simple operation and future expansion as business requirements can save time cost.

5) The ability to easily and quickly replace a faulty module significantly reduces mean time to repair (MTTR) and mean time between failure (MTBF), further enhancing uptime and availability.

As the fastest growing segment of the three-phase market, modular UPS sales are  expected to reach $2.5 billion by 2020.The appeal of modular power protection systems is driven by a range of benefits, including high availability, scalability, lower cost of ownership, ease of deployment, and reduced maintenance costs.


The difference between modular UPS and conventional UPS:

The first and most obvious advantage of the modular system is that it is smaller, with an implementation in a single rack rather than two cabinets. This is an important saving for modern data centers where floor space is at an increasing premium.

As UPS efficiency increases with loading, the modular units run with 96% efficiency compared with 91% for the standalone units. This improved efficiency not only reduces direct energy cost; it brings further savings through reduced cooling costs.

Increased availability is another benefit. Each UPS unit's availability can be defined as a ratio between its mean time between failures (MTBF) and mean time to repair (MTTR). And, whereas a standalone unit takes typically six hours to repair, some modules can be simply swapped in less than half an hour.

Modular systems are also generally designed to accept one more module than is required for their rated capacity, making them inherently "N+1" capable at much lower cost than would be possible with the very large system.
