In reality, there are two complicating factors. The power consumption printed on the back of an electronic device is usually the peak power, not the typical power. So, the VA value that you calculate may be grossly inflated, often by as much as a factor of two. Second, most UPS systems operate much more efficiently if the rated power of the UPS is somewhat larger than the rated power of the devices.

These two complicating factors tend to cancel out, so the technique to calculate the power rating is a safe estimate. You will find more accurate methods of calculating UPS power on the websites for many UPS vendors. Sites like American Power Conversion (www.apcc.com), Sutton Designs (www.suttondesigns.com), and Tripp Lite (www.tripplite.com) have online configuration calculators that will help you select the right power rating for your UPS.

A UPS consists of a battery and an AC inverter that work together to provide clean AC power during an outage. There are two main types of UPS: The standby UPS allows AC power to pass through and provides battery backup only in the event of a power dropout. The time required for battery power to activate is called the cut-over time or transfer time. An on-line UPS remains active at all times, constantly charging the batteries and feeding power to the computer.

On-line UPS systems have no cut-over time, since the battery is constantly feeding the system. On-line systems are more expensive, waste more energy, are tough on batteries and require frequent maintenance. For these reasons, the standby UPS is the popular choice for home use.

More capable consumer units with power for a high-drain computer and longer backup time ups cost around 150. High-end consumer units in the 1400VA range - enough power to handle three to four desktop computer systems juneau the juneau network or telecom hardware - may cost up to 600. Care and Ups The AC inverter circuitry and gel-cell chemical batteries in a UPS are fairly sensitive to abuse.
  • Some vendors provide a watt rating in the fine print on the box or the spec sheets on their websites.

Apcc. com), Sutton Designs (www. suttondesigns. com), and Tripp Lite (www. tripplite. com) have online configuration calculators that will help you select the right power rating for your UPS. Backup Time: The second crucial consideration is the amount ups time you will have to save your juneau and shut down your system in the event ups a power failure. Your backup juneau depends on the rated power of the devices attached to the UPS and the batteries in the UPS.

Most manufacturers list backup time in minutes at half maximum load - that is, the amount of time the UPS can provide power if it is loaded to only half its rated power. Some manufacturers also provide a backup time at full power load.

DO plug the UPS into
  • If not, you've got a problem.
  • Your computer display may be rated at 110V and 1. 5A, for a power rating of 165VA.
  • For example, your computer may be rated at 110V and 2A, for a power rating of 220VA. Your computer display may be rated at 110V and 1.

DO NOT plug laser printers, space heaters, kitchen appliances, power tools or other electrically noisy, high-drain devices into a UPS, even ups a short time. These devices will quickly damage the circuitry in the UPS. DO NOT plug medical devices or equipment juneau a standard UPS.

Power Rating: The power rating for a UPS is measured in VA, or voltage multiplied by current (measured in amps). You could also measure UPS-rated power in watts, but the VA number will always be higher, so VA makes for a more appealing number for marketing purposes. Some vendors provide a watt rating in the fine print on the box or the spec sheets on their websites.

To determine the required VA rating for your prospective UPS, multiply the voltage by the current for each device you plan to attach to the UPS, then add up all the VA values. You can usually find rated power consumption on a sticker on the back of the device, near the power cord. For example, your computer may be rated at 110V and 2A, for a power rating of 220VA. Your computer display may be rated at 110V and 1.5A, for a power rating of 165VA.

Add up the VA rating for all devices to get the minimum VA rating for your UPS. In this example, 220VA + 165VA = 385VA, so we'll need a UPS with a power rating of at least 385VA. In theory, this power calculation is accurate.

There are two key considerations in choosing a UPS: the rated power and the backup time. The rated power determines the maximum power of the devices that you attach to the UPS. If you use a UPS with an inadequate power rating, the UPS will fail immediately in the switch to battery power, leaving you with no backup power and a dead UPS.

The backup time determines how much time you have before the batteries run down. The backup time must be long enough that you can safely restore power or save your work and shut down your computer. Let's look at these two considerations in detail.
