We have tested 4 floor-mounted uninterruptible power supplies to find out how much they differ in efficiency, battery life and benefits per thousand rubles invested. In addition to the synthetic load, we used testing by servers, and also made sure of the quality of the sinusoid at the output of each of them. If you think all UPSs are the same, this article is for you.

If you think that UPSs have not changed over the years and these products have nowhere to develop, then you are wrong. Today we are reviewing the top model from Cyberpower, which boasts quiet operation from the mains, a pure sine wave at the output, a removable control panel, the ability to turn off non-critical loads and a pair of powerful 17 Ah batteries. It is a direct competitor to APC SMT1500i, and a competitor not inferior in functionality, but with a much better price and design.

Today we will look at the most unusual uninterruptible power supply that we have encountered before. This is the Protect C.3000S online model with reinforced high capacity battery charger and automatic bypass.

Rack-mountable 2U uninterruptible power supply up to 1000 VA from a company with 150 years of history in the power supply industry. Compared to competitors who have set the teeth on edge, this UPS has something to offer the user: here you can easily control it from the LCD screen, connect up to 6 additional battery blocks from the front, without disassembling the server cabinet, and unique sockets with locks. But what is more important for us - every detail of this UPS literally breathes quality, which is a rarity today.

The Energy Star standard, familiar to us from computers and monitors, means that an electronic device consumes significantly less energy in operation, and is more environmentally friendly. Similar certification is being introduced for data centers, albeit on a voluntary basis. Obviously, the documented title of an energy efficient data center is a good trump card for the company. However, there is too much uncertainty about this certification to invest extra money in achieving it.

Rack power remote power management can be a valuable service when it comes to reloading a dead machine. Remote power management for up to 40 devices using cascading, LED status indication, and built-in pinging system that automatically overloads a frozen server to increase the availability of the enterprise infrastructure.
