Power Back-up, Surge Protection, & Voltage Regulation

People the world over spend a lot of money on computers, software, and periferal equipment, yet the last thing to be considered—if at all—is the need to protect their investment of time and money with proper surge protection and power back-up equipment. Surge protection is just that: your equipment is protected against sudden spikes in electricity. There are products that will automatically switch to a back-up power supply, in the event of a complete power failure, and provide up to an hour of operating time. Your lights, radio, and refrigerator may all go off, but your computer will keep on running. When the battery goes below a certain point, the software will save and close all open documents, quit each open application, and power down the computer. Nothing lost.

An additional feature is AVR technology, or Automatic Voltage Regulation. House current is never 100% steady and can be affected by what is called "dirty power." If you do a lot of scanning, this feature will benefit you the most. I once tried to scan a large image by scanning the top and the bottom halves separately, and then assembling them in Photoshop. With only a minute between the two scans and using identical settings, the top half was signigicantly darker than the lower. The tiniest of power fluctuations can visibly affect the scan. AVR fixed that problem by delivering an absolutely consistent supply of voltage to my scanner. A prime example is William Mortensen's photograph, "Morocco," in the June issue.

Below are specs from two companies, Belkin and APC. Depending on needs and budget, each offers a variety of products and prices, however, for the purpose of this article, we feature some of the higher-end units for home computer use. Both companies offer products ranging from $79 to about $219. TheScreamOnline favors neither; judge for yourself.
