What is an Uninterruptible Power Supply

Most modern houses are stuffed with electrical devices. They all add to our life’s convenience, but electronic equipment is very sensitive to an unstable line voltage and power surges. The perfect solution is an uninterruptible power supply (UPS). This device has a powerful battery backup to provide your electronics with temporary power supply and save all the important data on your computer if utility power fails. The UPS will secure your gaming PCs, computer monitors, 3D TVs and smart TVs, all-in-one desktops, and many other devices. We have selected 5 best uninterruptable power supplies. You will find some useful tips on how to choose a perfect device in our best UPS review.

What Features to Compare

The first tip we'd like to offer is, while choosing and purchasing an uninterruptible power supply, look at the UPS Type. Today, there are two main types on the market: standby and line interactive. The standby UPS is used to feed the plugged electrical appliances or recharge a flat battery (when the line voltage is satisfactory). During voltage interruptions or deviations, the device assures a battery backup. As for the line interactive UPSs, they have an additional voltage stabilization function. It means that in the case of voltage fluctuations the UPS stabilizes a voltage using a transformer without any battery backup. If it is impossible to stabilize the voltage deviations during a power failure, the line interactive UPS switches to a battery power supply in 3-4 milliseconds.

The next thing you should keep in mind when choosing a UPS is Battery Characteristics. Firstly, consider the battery capacity measured in volt-amperes (VA) or Watts (W). Secondly, the UPS should have a 20% to 30% higher capacity than that of the electronics to be plugged in. To select an appliance with the appropriate power supply you should calculate how much energy would feed all the appliances you are going to connect to an uninterruptable power supply. For example, a 350-500 VA capacity would suffice for an LCD monitor, a PC with components of average parameters. UPS with 500-1000 VA power supply will feed game computers, high-power computers with two monitors. Uninterruptible power supplies with a capacity higher than 1000 VA will let you protect additional peripheral units. Another important characteristic is UPS wireless productivity. A standard UPS in household use provides your electronics with up to 15 minutes working under peak load conditions. This time is quite enough to save all your data and shut down your computer properly. Uninterruptible power supplies with reliable lead-acid batteries have a rather short recharge time, about 8 hours.

One more important point in choosing a UPS is its Power Surge Protection. In addition to a no-break power supply, modern devices provide an efficient data line protection. For example, a telephone, a computer network. Each interface has input and output connectors. In between them, there is a filter correcting high-voltage interferences. You can connect a router to a USP via a network cable. The most modern uninterruptible power supplies support data transmission to your computer through a USB or a COM port. Thus, a UPS gives you essential data on battery backup condition and charging, on electric network performance; informs you if the UPS turns to a wireless power supply; properly shuts down the PC while you're away; saves all the open app data in case of a power surge or fault. You can monitor and adjust the device performance from your computer. UPS manufacturers usually supply a specific software for this option.

The last important tip for selecting a UPS is to look through its Extras. Contemporary devices have displays for monitoring the UPS performance. As for the low-budget uninterruptible power supplies, LED indicators usually inform you about the device operation. Sophisticated models feature an LCD display with the detailed information on a USP condition and its performance, as well an audible alarm. A quick UPS power battery replacement will add to your device's convenience. As a rule, battery serves for 2–4 years depending on how often the battery backup is required. A replaceable device battery will prolong your UPS service life for minimum 2 years. Usually, UPS have both surge and battery backup outlets. You can use the former for appliances that need a surge protection only. They will not affect a battery backup power, which will extend the battery useful life; the devices with more outlets of this kind are preferable.
