Choosing the correct UPS for your power supply needs can be a difficult process if you aren’t up to date with recent advances. There’s a balance between cost and protection that helps to ensure you get t

In simplest terms, an uninterruptible power supply (or UPS) is a device intended to prevent a loss of power that could cause damage or disruption to an electrical system. Essentially, its a backup battery in the event your mains supply has a problem and it can make sure critical systems stay active long enough to shut down if you need prolonged power in the event of a disruption, you'd be best off looking at a diesel generator as a UPS will protect you for only a few minutes.

How does the flow of power work?

To help explain, we have a video discussing what a UPS does to prevent loss of power.

What does a UPS protect against?

There are four main problems that can befall your electrical supply, all of which can be safeguarded against by proper use a UPS system. These are

• Power Surges - A sudden increase in power flowing through to your device is typically caused by something like a lightning strike. This leads to a sudden increase in power followed by a drop which causes damage to equipment.
• Overvoltage - Overvoltage is when the power being supplied is greater than the power required and can cause overheating and damage. Unlike with a power surge, this power is over a sustained period and causes different problems.
• Undervoltage - Also known as a brown-out, Undervoltage is what occurs when the power supplied is less than is required. This could be from a sudden demand for power in other areas or a problem with the grid, the lack of flow leads to damage and active data loss.
• Power Outage - A complete disruption of power, either short or long term. There can be a number of reasons that you might be subject to a power outage but the results can be severe with data loss and system downtime being the major contributors.

By providing a constant flow of power, a UPS allows you to handle these problems as they arise. UPS systems moderate the flow of power and jump in with charged batteries in the event of total disruption.

What are the parts of a UPS?

A UPS consists of four primary parts which, when working together, provide you with a steady flow of power in the event of an emergency. They will likely be arranged in different formations depending on what version of a UPS you have available. An online double conversion UPS will have a different layout than an offline UPS, but both machine types consist of these four main elements.

• The Charger - Also referred to as the Rectifier, this is used to ensure your batteries remain charged while they're waiting to be activated. In order to do this, the incoming AC (alternating current) needs to be converted into DC (direct current) and it travels in this form through the majority of the UPS. The charger will be set-up differently

What Does UPS for Computers Stand For?

In computer and server terms, UPS stands for Uninterruptible Power Supply. An Uninterruptible Power Supply is a piece of electrical apparatus that is designed to supply power in the event of a sudden disruption in the supply. A standby UPS tends to have a power supply with a relatively short battery runtime that gives you a few crucial minutes to safely shutdown or save work before the battery runs dry.

UPS Systems Explained

An easy example of this in practice is when you pull the power cord out of a laptop, the laptop stays on and switches seamlessly to the internal battery. This is what a UPS does for computers, servers and other sensitive equipment.

What is a Server UPS?

Imagine you're in the middle of an important project at work, your data is stored on the server and you've been working at it for weeks. Suddenly, the power is gone – your
