Power Protection Devices
Several devices are available to protect against power fluctuations and
failures:
• Surge protectors
• Line conditioners
• Uninterruptible power supplies (UPS)
Surge Protectors
Surge protectors and power strips equipped with surge protection help to
prevent damage to your computer from voltage spikes that can occur during
electrical storms or following power interruptions. The level of protection is
usually commensurate with the cost of the surge protector. Some surge
protector manufacturers include warranty coverage for certain types of
damage. Carefully read the device warranty when choosing a surge
protector. A device with a higher joule rating offers more protection.
Compare joule ratings to determine the relative effectiveness of different
devices.
NOTICE: Most surge protectors do not protect against power fluctuations or
power interruptions caused by nearby lightning strikes. When lightning occurs
in your area, disconnect the telephone line from the telephone wall jack and
disconnect your computer from the electrical outlet.
