Understanding UPS For Computers
Know Your APCs
As previously mentioned, the king of the heap in power products is APC — American Power Conversion. Once premium priced across their lines, APC have delivered a huge variety of options that can meet the power needs of almost any individual or business.
Based in Rhode Island, these guys have been around since 1981 and more or less created the UPS business. APC stuff is available at both Tiger and CDW as well as hundreds of other retailers like Staples, Office Max and Wal-mart. Almost all APC products come with a $50,000 to $150,000 equipment protection warranty, which helps make up the premium price in our opinion. (Note that these warranties never protect data)
CyberPower, SmartPro, and ULTRA are among the quality competition for APC, though not every company makes every kind of unit.
Power is nothing, without power
The most important things to understand when buying an “uninterruptible” power supply are:
· What exactly you need the unit to do
· How often you probably need it to do it
The main categorical difference among units is their wattage. Generally speaking 700 Volt Amp units and smaller are viewed as one group, and 700VA and higher as another. Roughly speaking this is “desktop” units and “network” units although wattage needs vary. Bear in mind that most stand-alone UPS solutions are intended to allow you to backup your system and shut down safely, not keep running any great length of time (which would require a generator). Think of them somewhat like a donut spare.
Desktop examples
Desktop UPS systems were once rare and expensive but are now common and relatively cheap. These units typically include a world-class surge protector so that is a piece of equipment you will not need to also purchase, depending on how many outlets you need. For example: If you need to keep a desktop going in the event of a short-term power failure, you need to decide, for example, if you want to safely shut the computer down, or actually keep it up and running off the emergency batteries.
The APC Back-UPS line designed for a single desktop ranges in price from about $39 to about $199 as of this writing.
For $39 (Model Back-UPS ES 350) you get about 50 minutes of runtime with three battery-powered outlets, three additional surge-protected outlets, 200/350 watts/VA and a $50k equipment insurance policy. Each of the price points up to $199 (Back-UPS RS 1500) gets you more outlets, more peak wattage, longer runtimes to 110 minutes, and more insurance.
