Everything You Need to Know About UPS

Power interruptions may sometimes be quick and short, but they can cause serious damages to your valuable devices. Disturbances can either make an internet router require rebooting or a certain system to hang. These things not only affect the lifespan of your devices but also your workflow. If you want to stay connected to your Wi-Fi to close client deals or enter your data on time, then you need a UPS in the office.

An uninterruptible power supply (UPS) is a battery-based backup system that instantly provides energy to electronic devices such as personal computers, television, fax machines, and more. It’s like a buffer system that protects anything that is plugged into the unit from unexpectedly shutting down, and allows it to continue to function. Although the battery has limits, the runtime should be enough for you to save your files and properly turn off your computer.

However, not all UPS products you will see will be the best one for you. There are three types of UPS units to choose from and each of them is best applied to certain conditions. Aside from this, there are so many brands on the market which can make your task to find the best UPS a challenge. This article will provide all the necessary information you need to decide which model to buy.

Advantages and disadvantages of using a UPS

Before you decide whether you need a UPS or not, you need to understand its advantages as well as disadvantages. This way, you will be more convinced why it is better than the other power backup system like generators.


  • A UPS can protect your computers and other electronic devices from being damaged during power fluctuations, or you losing valuable data
  • It can keep your business running for a particular amount of time, which is enough to close sales deals without sudden interruptions
  • They work almost the same as a generator but they are silent, cheaper, and requires no maintenance
  • Extends the life of your equipment because it prevents any electrical problems caused by fluctuations or sudden blackouts
  • Electronic devices will experience no lags and delays when plugged into the unit


  • They are only ideal for computers, televisions, and modems, and not for heavy-duty appliances that require a greater power supply to operate
  • Batteries are the most expensive part of the unit. If you bought a low-quality UPS, you might need to change the battery frequently in a year
  • You will need an expert electrician in fixing problems with the unit since it could cause more serious problems if you do it by yourself

Steps in identifying the best UPS you need

Just like in buying a new laptop or any electronic device, you need to consider different factors in order to find the product that has the right specifications. To help you choose the best UPS, here are the steps you should follow.

Identify all the equipment you want to plug into the UPS for protection and backup battery

If you are working in an office, include in your count the monitors, hard drives, Wi-Fi modems, and other important devices you always need running. Then look for a UPS unit that has a sufficient number of outlets to accommodate all of your equipment. Most people buy more than one unit to connect all the electronic devices that need protection.

Total up the power or amperage ratings of all your equipment

One important tip in choosing the UPS is to make sure that the total power capacity of the unit is at least 25% greater than what the devices need. It is essential to operate within the safety margin to ensure that the UPS can give enough running time to each equipment. Another reason for this is for future expansion or for added equipment to plug in.

Know where are you going to install your UPS

If you are just using it at home, then an offline UPS would be enough. However, if you are going to install it at the office, you might need a line-interactive or online UPS. These two types are ideal for both small and big businesses.

Three types of UPS

In simple terms, a UPS works like this: A rectifier stores the converted DC power and charges the battery that will be used as a backup for your equipment. But before the required energy arrived in the device, the battery sends power to the inverter. Then the inverter converts the power back to AC power, which is what electronic devices needs.

There are three types of UPS. Each type is the best in their own way; they have features that make them a better choice over the other. For you to know which one of them will be the best UPS for you, you need to know how they work as well as where you can best apply or install them.

Offline UPS

The basic type of UPS is the offline UPS. It is ideal to be installed at home where there are only a few devices to plug in. The unit mechanically switches to battery backup when there is a power interruption. However, compared to other types, there is a possible lag that will take up to 25 milliseconds.

Line-interactive UPS

If you are running a small business, then you might want to choose a line-interactive UPS instead. This type is a little advanced compared to the offline. There are shorter lags when switching from utility to battery, and with the help of automatic voltage regulation, your devices are more protected from a sudden surge. Some models also have noise coils that filter the electromagnetic line noise.

Online UPS

The online UPS is the most advanced type and the most expensive among the three. It is great for areas that often experience power fluctuation as well as for sensitive devices that are prone to system damage. It automatically changes to battery mode without switching because the batteries are always connected to the inverter. This way, the runtime is longer and there are no lags in between. Aside from this, its noise filter feature is more effective.
