Factors to consider when purchasing a ups

An uninterrupted power supply(ups) is a device that allows a computer to keep running for at least a short time when power source is lost. The ups also acts as a surge protector. It protects connected devices from power problems like surges or abnormal voltage.

Why do i need a ups system

In case of a blackout, the system kicks in to provide a continuous power source for the length of the battery. The battery backup gives you time to shut down sensitive equipment like servers and gives you time to save up important data.

Types of ups system

There are three topologies

  • Standby

Provides power to the computer only when it loses AC power

It uses automatic voltage regulation(AVR) to correct abnormal voltages without switching to battery

  • Double-Conversion

These UPS systems provide your facility the highest level of protection by isolating the equipment from raw utility power. The system works by converting power from AC to DC and then back to AC.

What Type of Ups do i need

  • How many outlets do you need

You must determine how many devices you need to plug in. The number of devices determine the number of outlets you will need. It is advisable to buy a ups with the outlets you need plus two, since it gives you room for additional devices in the future.

  • How much time do you want electricity once the power goes out?

A ups is supposed to give you time to save files and properly shut down equipment. When shopping for runtime, you will be looking at the length of time the batteries in the UPS can support equipment through power outages when utility power is unavailable. Remember that the number of watts supported affects runtime: the smaller the wattage load connected, the longer the batteries will last. The larger the wattage load, the shorter the runtime will be.

  • How much power do you need to provide

You will have to determine how much power the devices connected to the ups need. If the devices need more power than the UPS can generate, they’ll go dead, even if the battery has plenty of energy remaining. The rule of thumb is to get a UPS with a power capacity that is 25% higher than your total power needed.

  • Tower or rack mount

When choosing the form factor, the main consideration is where you are going to use it. A desktop or compact UPS can hide under a desk, unnoticed. A tower or mini-tower will have a pleasant aesthetic design making it an option to sit on top of a desk or table. A rackmount UPS works well in server rooms.

  • Warranty

Various companies offer different types of warranties for the UPS system and batteries they provide. As standard they are generally 2-3 years on electronics and 2 years on batteries. Compare between various companies and then decide which is the ideal option


Putting into consideration the above factors, you can ensure you have the most ideal UPS that matches your needs. And with the right UPS system for your home or office you can be assured that your equipment will be protected in the best possible way.
