An Uninterruptible Power Supply (UPS) system provides back-up power to devices like computers, appliances, and even mobile phones. It stores power by connecting to the device and the socket. When the power goes out, the UPS system automatically turns on so you can enjoy uninterrupted use of your device.
Used with your computer, a UPS system can provide you with ample time to save data, close programs, and shut down properly during power outages.
The two types of UPS systems are the standby power system (SPS) and the on-line UPS system.
An SPS directly monitors the power of your devices. It automatically converts to battery power the minute it detects problems with the main socket. It also has a quick power transfer allowing for uninterrupted use of the device.
The on-line UPS system allows for continuous use of device, with no power lapses. It functions even when there is power, storing power from its own system. On-line UPS systems are usually more expensive and more reliable than the SPS.
When buying UPS systems, it is important to look for two things: extended runtime and warranty. Look for a UPS system that provides extended runtime during power failure. Before buying a UPS system, it is also best to check first your device’s compatibility. An incorrect UPS can cause damage to your device, costing you more money.
