What Are They?
Brownouts are periods of low voltage in utility lines that can cause lights to dim and
equipment to fail. Also known as voltage sags, this is the most common power problem,
accounting for up to 87% of all power disturbances.
Do They Come From?
Overburdened utilities sometimes reduce their voltage output to deal with high power.
Recent statistics show that the U.S. population tries to pull an average of 5% more than
utility companies can provide. The demand for power is rapidly increasing, but the supply
of power is not.
Damage to electrical lines and other factors can also cause utility
brownouts. Locally, equipment that draws massive amounts of power such as hair dryers, air
conditioners, or laser printers can cause momentary brownouts to occur.
Undervoltages are often followed by overvoltages - "spikes" -
which are also damaging to computer components and data.
What Do They Do?
Voltage variation can be the most damaging power problem to threaten your equipment. All
electronic devices expect to receive a steady voltage (120 VAC in North America and
220/240 volts in many other parts of the world) in order to operate correctly.
Brownouts place undue strain on power supplies and other internal
components, forcing them to work harder in order to function. Extended brownouts can
destroy electrical components and cause data glitches and hardware failure.
Overvoltages burn out power supplies and other components and can cause
massive damage to your electronic hardware. Extended overvoltages can even cause fires as
electronics "fry" in the extra electricity.
What Can I Do?
Surge suppressors only do ½ the job - protecting you from over-voltages. Line Conditoners are your best defense against both voltage problems.
Designed to regulate both over and under voltages, our Line Conditioners
provide three separate levels of voltage correction. This advanced design adjusts voltages
from 87 to 140 VAC (168 to 278 for INT models) to provide your equipment with safe,
computer-grade AC power meeting ANSI C84.1 specifications. And since all Tripp Lite Line
Conditioners include advanced surge and suppression circuitry, you can protect against all
three types of power problems with a single unit.
