Ippon is a brand widely known for its uninterruptible power supplies. Not so long ago, power distribution units were introduced, namely three models - PDU Basic 0U, PDU Basic 1U and DU Meter 0U. We got the first model, Ippon PDU Basic 0U, which is designed for power distribution in the server rack.

Lithium ion batteries offer several advantages over the traditional valve regulated lead acid (VRLA) batteries commonly used in UPS systems today. Much longer battery life, smaller size and weight, faster recharge times and lower prices have made lithium-ion batteries an attractive energy storage technology.

Today we are testing a brand new line-interactive UPS from APC by Schneider Electric of the Easy UPS series, designed to power loads such as desktop computers, television equipment, ATMs and terminals, as well as other devices without increased power requirements.

Each of the new bypasses can be used to supply the load directly from the mains to exclude the uninterruptible power supply (UPS) from the power supply system so that the UPS can be changed without shutting down the server.

Today, few people buy UPS "for centuries", therefore, in the mass sector, manufacturers compete in compactness and cheapness. We have tested Cyberpower products from the moment they began to be sold in stores, and these uninterruptible power supplies have always received high marks from our editorial staff, therefore, taking into account the merits of our ancestors, we will have increased requirements for the new UPS.

When choosing a UPS for installation in a rack, the buyer, as a rule, focuses on price, capacity and number of outlets. In our reviews, we not only measure performance, but also pay attention to the design of the device, and sometimes in the most budget models you come across such an engineering thought for which you want to shake hands with the developers. Today we are testing a double conversion UPS from PowerMan.

Today we will test a conventional 1000 VA Tower Online UPS belonging to the budget class. UPSs like these are installed to protect high-value stand-alone equipment such as ATM machines, medical devices, and various telecommunications systems. Its low price makes it a competitor to linear interactive models.

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. What is even more interesting - the UPS itself does not have built-in batteries and is assembled in a free-standing case, that is, you can use any external batteries! Who might need such a model?

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.
