How UPSs increase your scalability and efficiency The loss of energy in critical applications can have serious consequences and we know that UPSs exist to avoid it, but have you thought about it. We offer best cost for APC PDU prices in Pakistan.

What Would Happen If the Ups Were to Fail as Well?

What Is Efficiency?

We understood Efficiency as the benefit obtained between what we used and what we achieved. A team is efficient if the result is greater than what we used. The relationship of how efficient something is with the following formula:

Efficiency = Result / Resources

If this ratio is less than 1; the equipment is inefficient and is costing more than it produces.

If it is = 1 the team will not gain any benefit; but if it is greater than 1, it can say that the team is efficient; the greater than 1 the result, the more efficient the team will be.

But Why Is UPS Efficiency Important and How Is It Determined?

With the previous concept we can say that the energy efficiency of a UPS is determined by the difference between the amount of energy that enters vs. the amount of energy that it leaves or provides. In any UPS system, part of the energy we lost mainly as heat.

What Is a Modular UPS?

Recently, the trend has been to use smaller power modules and gradually create a larger system as the application requires. The reason behind this trend is due to the fact that the need to consume IT systems is no longer constant, but rather requires flexibility in terms of growth, change or evolution based on market demand.

A modular UPS is a group of power modules located in a single cabinet that work through a central control system, which manages the operation of the entire system. This means that the UPS must be scalable so that the user can add power capacity in the available spaces or add redundancy to one of the existing modules.

According to an investigation carried out by experts in the field, the market demand for a modular UPS can summarize in the following key points:

  • Flexibility and scalability
  • Improved efficiency
  • Utility
  • better availability

Flexibility And Scalability

This is one of the most obvious advantages of modular UPS systems, the ability to gradually adapt to the load’s current consumption demand. Because a modular UPS is scalable once deployed, power capacity can increase or decrease while in operation.

The flexibility is quite useful in applications where cannot completely defined the load cannot completely defined at an early stage, for example, when there are plans for constant and progressive growth of the data center. This flexibility is also often useful when the UPS must achieve different capacity levels depending on its location.

Flexibility and scalability

Improvement In Energy Efficiency

As is often the case with many electronic systems, optimize the design to function over a range of operation under certain conditions. By being within those conditions, obtain higher performance, as well as greater efficiency.

In the case of a conventional UPS, we designed it to achieve maximum efficiency at 70% or 80% of its nominal capacity, which means that, operating at a capacity less than this percentage, we will have a lower efficiency, for example, at 30%, 40%, 50%, etc.

With a modular UPS, thanks to its growth capacity, it is much easier to adapt it to the requirements of the load as it changes, thus operating in more efficient conditions, since its capacity can match the requirements of the load at that moment.


In terms of utility, in a monolithic UPS when maintenance require, it is necessary to switch to maintenance bypass mode, with the risk of not having a backup. In the case of a modular UPS this is completely different, since generally the inverter, rectifier and charger system assemble in a separate “box”. But more importantly, this module can insert and removed from the framework while we still powered the load by the other modules, this translates to:

Faster power module replacement than individual component replacement or repair

Reduction in repair costs

Reduce downtime


Better Availability

Availability refers to the availability of the continuous operation of the complete system. We calculate by combining the mean time between failures (MTBF) and the mean time to repair (MTTR).

So, if we have a highly reliable product and we combine it with a feature like the quick extract feature that we mentioned in the utility, this will give us higher availability. Availability is a key piece in modular UPS as they are one step ahead to ensure the continuous operation of the load.

better availability

When purchasing a UPS, the data must request from the supplier and the efficiency tests carried out in the factory (linear or ideal conditions). However, for real conditions, it is necessary to take into account the load level with which you will work. That is why we recommend it to request the precise efficiency of a UPS; every manufacturer must show the efficiency of its equipment at a level of less than 50% of its capacity.


As you can see, there are numerous benefits of having a modular UPS in your system, however the point to highlight is that the use of a modular UPS will allow you to achieve maximum availability for the load.
