A handbook to UPS systems

What is the UPS system?

When the utility power shuts down and continues to apply energy to the equipment, this system kicks in. Simply put, a UPS power supply is a backup battery power system. It allows devices sufficient time to shut down properly.

This reduces the risk of data loss and the stress a forced shutdown causes to the electronic pieces of equipment. This supply also acts as a surge protector. It safeguards connected devices from power issues like surges or irregular voltages. These factors tend to affect equipment and machines’ life span and performance.

The types of UPS systems

There are three common what is turinabol types of UPS power supply systems available based on the power protection needed.

  1. Standby
  2. Line-interactive
  3. Double-conversion

Common types of power problems

Blackout is the most common power problem that most individuals have faced. There are many more power problems that exist. 


There is a brief but intense spike in electricity. It is most commonly caused by lightning. Surges are capable of causing damage to electronics. The intensity of the point in electricity or voltage can damage the circuit board and components. 


This is a common occurrence. An interruption that lasts from a few seconds to days. Usually caused by extreme weather conditions, accidents, failure of the power grid, and power shortages.


It is caused by the drop in voltage for a prolonged period. This drop could be intentional or unintentional. Power companies tend to reduce the voltage to avoid a complete blackout in an emergency.

Voltage Sags

It is very similar to a brownout caused by a drop in voltage. However, it lasts for a brief period and is short.

Frequency Noise

It is also known as line noise. This noise degrades the circuit’s performance by introducing abnormalities into it and disrupting the system.

Frequency Variation

This is a rare occurrence when there is a stable power supply. It is most commonly observed when generators are being used. This leads to a more significant fluctuation in the power frequency than desired.

Over Voltage

When the voltage received is higher than the usual range, over-voltage is observed. However, this difference does not last as long as a surge or spike.

How to identify the UPS capacity?

For your UPS system to run correctly, it needs to support the various equipment plugged in. Capacity is the power that the UPS power supply can provide (in Watts). The greater the capacity, the more significant number of support devices.

To calculate the capacity, you need to find the load. This includes the power requirement of every equipment and device that will need to be supported by the UPS. Once you have the total load, Total the number of cords plugged into the UPS. Ensure that your UPS system has the needed number of outlets.

How should my UPS look?

There are three classic look types when it comes to UPS systems. It is decided based on the shape and size of the external segment. The three types are:

  1. Desktop models
  2. Tower models
  3. Rack-mount models


When buying a UPS unit, calculate the exact capacity you require based on your needs. It will provide your devices with protection for an extended period and is a one-time investment.

Ensure to do your study and invest in the same UPS system that provides you with all the features you are looking for.
