The term "line noise" refers to random fluctuations -
electrical impulses that are carried along with standard AC current. Turning on
the florescent lights overhead, your refrigerator, laser printers, working near
a radio station, using a power generator, or simply working during a lightning
storm can all introduce line noise into your systems.
Ever notice the "snow" on your TV when you use a blender or a
hair-dryer? That?s line noise being sent back into your electrical system and up
into your TV.
What Can It Do?
Line noise interference can
result in many different symptoms depending on your particular situation. Noise
can introduce glitches and errors into programs and files. Hard Drive components
can be damaged. Televisions and computer monitors can display interference as
"static" or "snow," and audio systems experience increased distortion
What Can I Do?
Tripp Lite Surge
Suppressors, Line Conditioners and UPS units include special noise filters that
remove line noise. The amount of filtration is indicated in the technical
specifications for each unit. Noise suppression is stated as Decibel level (Db)
at a specific frequency (KHz or MHz). The higher the Db, the greater the
protection. Be wary of "surge/noise suppressors" that don?t provide this
Isobar surge suppressors take noise suppression to a new level
with their exclusive Isolated Filter Banks. These special banks prevent
line noise generated from one device from traveling through the surge suppressor
to interfere with other connected equipment. So if you use a laser printer (a
notorious source for line noise) you can connect it to the same Isobar that
powers your computer without putting your equipment in danger.
Tripp Lite Isolators, with their Faraday
Shield design provide true line isolation and exceptional line noise rejection -
even at low frequencies where it is difficult to control. Isolators eliminate
the need for costly rewiring or dedicated lines by providing clean, computer
grade electrical current from even the "dirtiest" power.
