The Fundamentals of Choosing a UPS System

  |   UPS   |   No comment

When it comes to choosing a UPS for your large-scale industrial or data centre applications, there are a large number of systems to choose from. Most manufacturers of these systems customize the UPS’ for their clients. If you are considering buying a UPS for your unit, there are many different aspects to keep in view. Here are some pointers that will set you in the right direction. Purchasing the right UPS is about having complete information about what these systems are, how they work and more. Read on to learn about the fundamentals of choosing a UPS system.

Understanding What A UPS System Is

A UPS system, in its most basic form, is a system that provides battery backup power for equipment to be shut down properly in case there is a utility power failure. In a data centre setting, it helps prevent data loss. In the case of manufacturing units and other applications, it reduces the stresses that hard shutdowns cause on your equipment.

Aside from this, UPS systems also provide surge protection to the connected devices from different types of power problems such as abnormal voltages and surges that can impact the performance of the equipment or devices, reducing their lifespan or causing damage to them.

Why You Need a UPS System

In case of loss of utility power, the UPS will immediately switch over to the battery power in order to ensure that the equipment, devices or data centres have a continuous power source (for the duration that the battery is built for). This gives you the time needed to power down servers, equipment, and sensitive devices.

Types of UPS Systems

UPS systems essentially have three different categories or topologies, based on the type of power protection required; these three topologies are:

Common power problems that can arise


This power outage can last from anywhere between a few seconds to several days. Blackouts are typically caused by power grid failures, utility power shortages, inclement weather as well as accidents.


An intense, yet brief spike in the electricity levels, typically caused by lightning. Surges can cause significant damage to electronics and sensitive equipment and can destroy circuit boards and other components.


This is an unintentional/intentional drop in voltage for extended periods of time. In emergency situations, the utility companies might lower the power supply voltage. They do this reduce the strain on the resources as well as to avoid a complete blackout.

Over Voltage

This occurs when the incoming voltage is far higher than normal and it also lasts much longer than a surge. However, it isn’t high enough to be called a spike or surge.

Frequency Variation

This isn’t a very common problem in times when the power supplies are steady. However, it can occur when generators are being used and there is a wide power fluctuation.

Harmonic Distortion

A move from the ideal electrical signals on specific power sources.

Frequency Noise

This may also be referred to as line noise and it can degrade or disrupt the circuit’s performance by causing abnormalities in these systems.

When you are choosing a UPS system, you would need to keep in view aspects such as:

  • The setting in which it will be installed
  • The application
  • Type of system
  • The protection it offers
  • Size and capacity of the system
