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.
