Have you ever noticed your lights dim or flicker when you turn on your dishwasher or
air-conditioning? This common occurrence is attributed to an under-voltage of power,
also known as a BROWNOUT.
A brownout is a period of insufficient power-line voltage. It is the most common power problem,
accounting for 80% of all power disturbances. Other origins of disturbances also vary, ranging from
atmospheric phenomena such as lightening or frost, to near by devices generating interference
such as elevators, photocopy machines and machinery, not to mention human errors such as the
accidental removal of power cords or tripping of circuit breakers.
Effects:
A power disturbance such as a surge, spike, swell, line noise, brownout or blackout can
deprive a computer of the power it needs to function, causing unwanted damage to your
computer, such as frozen keyboards and hard drive crashes. Such problems will cause you to
incur computer repairs, lost data and downtime.
Solution:
A Belkin Uninterruptible Power Supply (UPS) with Automatic Voltage Regulation (AVR).
Typical "Stand-by" UPS units do not have AVR to increase the output voltage or decrease the
output voltage to your computer. A surge protector can only protect your computer from
over-voltages due to irregular power. Belkin UPS units protect against surges, spikes, swells,
line-noise, brownouts and blackouts!
Only a Belkin UPS with AVR can give your computer clean and consistent
power at all times.
NOTE:
There is no guarantee that interference to radio/TV will not occur in a particular instal-
lation. If this UPS causes interference to radio or television reception (this can be deter-
mined by turning the UPS power off and on), the user is encouraged to try to correct
the interference by one or more of the following measures:
• Connect the equipment to an outlet on a circuit different from that to which the
receiver is connected.
• Increase the separation distance between the equipment and the receiver.
• Reorient or relocate the receiving antenna.
