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.
