Features of Online UPS

A genuine online UPS provides conditioned clean power all the time due to the fact that UPS is continually converting from AC to DC and back again to AC. There is never interruption of power or any transfer time to the load is a brownout or a blackout occurs.

Line Interactive UPS have been created to ensure that you enjoy unlimited power supplies. Line interactive UPS is just a reserve UPS with an additional multi-tap variable-voltage autotransformer.

Traits of a Great UPS

Automatic voltage regulation (AVR): We required our upgrade-pick contenders to have AVR, and we strongly preferred it in all other models. AVR, also called line-interactive topology, is a more advanced form of power management than the type that less-expensive models use. With AVR, when power from a wall outlet briefly dips or surges outside of a specified range, a small transformer in the UPS acts like a buffer to compensate without relying on the battery; the UPS switches to battery power only when the transformer can’t handle the variation. This reduces wear and tear, especially if you live somewhere with frequent brownouts, and prolongs the overall life of the battery. It also provides more-reliable power to sensitive gear like hard drives.

At least four battery-backed outlets: All outlets on a UPS provide surge protection, limiting the amount of extra voltage that can reach and potentially damage your devices which is good because you should never plug your UPS into a surge protector or plug a surge protector into a UPS. But generally only half the outlets are connected to the backup battery (and are prominently marked as such) so that they stay on when the power goes out. It’s always good to have more outlets for plugging in more devices, but the outlets that really matter with a UPS are the battery-backed ones. A set of four battery-backed outlets is enough for you to plug in a modem, router, desktop computer, and external hard drive just make sure to plug the right devices into the right outlets.

At least a 5-foot cord: A long cord is helpful if your wall outlet isn’t right next to your workstation, especially since it’s unsafe to plug a UPS into an extension cord. We think a 5-foot cord should be long enough for most people, but when an even longer cord is available, we prefer that.

User-replaceable battery: Most UPS batteries are small, sealed, lead-acid batteries—more like a car battery than the one in your smartphone or laptop. We tested only those models that have a user-replaceable battery, which allows you to spend Ksh 2500-6000 on a new battery instead of having to buy a whole new UPS.

Power-management software: Even though most people won’t go through the trouble of installing such software, most UPS makers offer an application you can download to monitor and manage a UPS (over USB) from your computer. You can also program it to complete a series of tasks before shutting down if you’re away from your computer when the power goes out which is especially handy for units with shorter run times. Even better, software that works on any operating system is future-proof even if you replace some of your equipment, so your UPS can be just as useful years down the line as it is the first day you plug it in.

Warranty for a year or more: Most brands we looked at back their devices for upwards of three years, but we think a year is plenty of time to test out your UPS and determine if it’s working properly. And since power outages happen about once or twice per year Kenya, you’re likely to have tested it against a real-world outage in that timeframe, too.

USB ports: For charging a phone or some other small device, using a built-in USB-A or USB-C output port is more convenient than taking up one of the outlets with a multiport wall charger. These ports aren’t connected to the battery, though, so you won’t be able to use them during a power outage.

Backlit screen: A small status light is all it takes for your UPS to tell you that it’s up and running, but some of the pricier UPS models have a screen to display additional information such as the battery’s charge status, current load, and remaining run time. This information helps to ease low-battery anxiety when the power goes out and you’re rushing to save your work in time.

Battery capacity (watt-hours, or Wh) and run time: Manufacturers often publish run-time ratings that outline how long a UPS can keep devices at various wattages running. Since most ratings are based on ideal conditions, we tested our top candidates at two different loads to see how they would perform in real-world use
