How does a computer’s UPS work?

Your computer or laptop is able to withstand slight differences in power, but a significant change will cause the power supply to fail! A UPS is generally there to protect your PC against these different power problems…

Surges and spikes – Times when the voltage on the line is much more than it should be.

Sags – Times when the voltage on the line is less than it should be.

Total power failure – Times when a line goes down or a fuse blows somewhere on the grid or in the building or area.

Load shedding – Times when the power is cut purposely to avoid excess load on the power system.

Frequency differences – Times when the power is swaying at something other than the right frequency.

There are two common systems that we use today, standby UPS devices and continuous UPS devices. A standby UPS runs the computer off of the normal power until it detects a problem. At that point, it will very quickly turn on the power inverter and run the computer off of the UPS’s battery.

In a continuous UPS, the computer is always running off of the battery power and the battery is always being recharged. It is possible to build a simple UPS yourself, using a large battery charger, a battery and a power inverter. If the power fails, the battery will then give power to the inverter. There is no switch-over time in a continuous UPS device.

Standby UPS systems are far more common for home and small-business use because they tend to be a lot cheaper than a continuous UPS. Continuous systems provide clean, stable power, so they are usually used for servers.

Off Grid can provide you with backup power solutions for you or your business, including a variety of UPS devices. Our load shedding solutions are both easy to work and affordable, so when the power goes out, you will not be inconvenienced.

What is a UPS?

Power cuts, because of the dreaded load shedding, can not only cause you to lose unsaved work and precious data. It can also damage your valuable hardware and network infrastructure. So how do you protect your computers from load shedding? Enter the UPS…

A UPS, or “Uninterruptible Power Supply,” is any device that keeps your computer powered up and operational in the event of a power interruption. Simply put, a UPS is a battery that provides power to your computer or other critical hardware when its primary power source is unavailable. When your computer’s power source is lost, the UPS provides power for a certain amount of time (usually 10 or 15 minutes) so you can save your work and properly shut down your systems.

If you operate your business on a network or have various peripherals connected to your computer, a UPS system can be used to protect multiple devices, including monitors, modems, and routers. Most Uninterruptible Power Supplies will also shield these network systems from damage that may occur from power cuts and surges.

A UPS comes in two basic types: standby or continuous. A standby UPS, as the name implies, doesn’t switch on until power is interrupted. When it detects a loss of power, it switches on immediately (within 5 milliseconds). Most commercial UPSes are of the standby variety.

A continuous UPS, on the other hand, is always on and acts as a battery that powers your computer. A continuous UPS charges itself on power from a wall plug, and in turn runs your computer or other hardware system. This acts as a buffer so that no matter what happens to your power — be it surge, or load shedding — your critical machinery receives a clean, reliable flow of juice.

Uninterruptible power supplies range in price. Some Uninterruptible Power Supplies even include software that automatically saves your open files and shuts down your computer if its power source is compromised.

So before you buy another piece of costly computer hardware, consider investing a little money in a UPS. It can save you the headache of losing valuable data, and, in the event of a power incident, it just might save you some serious money by protecting your infrastructure investment.
