An uninterruptible power supply (UPS), also called a backup power supply, is a device for maintaining the operation of a computer or other electronic devices when the input power source is interrupted. An uninterrupted power supply may provide protection from power outages and temporary interruptions in primary power from its main electricity, generator, or battery.

Surge protectors and Uninterruptible Power Supply systems are two terms often used interchangeably. Despite this, they are not the same thing although they provide similar results. A surge protector is a device that works with a standard outlet to protect electronic devices from electrical power surges and spikes. An Uninterruptible Power Supply system is an external battery that provides backup power for computer systems and important electronics in the event of a power outage or other emergency that takes out normal power sources.

Uninterruptible power supplies or UPSs serve the same purpose as surge protectors: to prevent damage to your electronic devices in the event of a power outage. However, there are some differences between them. If a power outage occurs, UPS devices provide sufficient power from their internal battery to continue running your PCs and other electronics, allowing you the time to safely shut them down. Surge protectors help keep your connected equipment safe from electrical surges caused by electrical storms and other types of power abnormalities.

Electrical grids are subject to surges and these can damage appliances, computers, and media centres. Surge protectors prevent expensive electronics from being damaged in the event of a surge. Surges can happen when the electrical grid is stressed, for example during a heat wave when everyone is running their air conditioners. The risk of damage from surges goes up as more and more people use appliances that are sensitive to power fluctuations. Surge protectors provide peace of mind by protecting costly electronics and appliances.

Whether in your home or office, it's important to have a power system that protects against power outages, surges, and spikes. That's where surge protectors come in. They can help prevent damage to your equipment due to a sudden change in voltage but they do not offer continuous power protection like UPS systems. The main difference between a UPS and a surge protector is that a UPS provides clean power no matter how much electricity is lost through the grid or if there are power surges, while a surge protector only has limited shielding around an outlet. You can increase your coverage with both devices by using both in conjunction with each other. Eaton offers a range of UPSs and surge protectors that work seamlessly together so you get the best possible coverage for your home or office environment.
