Protects against high and low voltage, brown-outs and voltage dips.
These conditions are extremely harmful to electrical and electronic
equipments. By disconnecting the power when it is bad and when it's
bad and reconnecting automatically on return of normal power, the
AVS15 Aircon Guard safeguards and protects against short term and
long term damage to ensure longevity of your appliances, especially
air conditioners and refrigeration equipments. Reconnection takes
place after a start-up delay to protect against frequent

Spikes/Surge: Very short, (onemillisecong) event of very high surge
in voltage to thousands of volts and AMPS. Spikes are common in all
parts of the world and repeated exposure to spikes will damage
electronic equipment and corrupt data. What causes it? Switching
on/off of nearby equipment, lightning, motors starting etc.
RFI (Radio Frequency interference) Noise: High frequency
disturbances that occur within a short period of time
(milliseconds), RFI & noise are very common in all parts of the
world and are the main cause of data corruption. What causes it?
Generated by high frequency noise from nearby equipment,
transmittes, mobile phones, switching on/off of certain loads,
fiuorescent lights, motor speed controls, light dimmers.
Over-Voltage: Long duration(milliseconds, seconds, minutes, hours
or days)rise in the voltage above acceptable limits. Depending on
the lecel of the over-voltage, the damage can be instantaneous,
severe and irreparsble. What cause it? On return of mains supply
after power cuts, under-sized utility oscillating between periods
of brown -outs and over-voltage or accidental (e. G. Accidental
connection between two phases).
Brown -Out: Long duration of low voltage (milliseconds to seconds,
minutes, hours or days). What causes it? Most commonly an over
-strerched utility, espevially in areas of poor power distribution
infrastructure and remote areas. Common in dry seasons where water
is used for electricity generation.
Lightning: Direct or nearby strikes can cause minor problems or
severe disyurbances and damage. Lightning peoduces spikes/surges,
over-voltage or power cuts, What cause it? The surgeis gengrated bu
either a directhit, or indirectly striking underground or overected
equiupment in nearby buildings.
Power-cuts: Common in every country in word, especially in areas of
frequent voltage problems. Suddenloss of power can cause damage
ranging from corruption of data to mechanical faults as equipment
is stopped while in operation, What causes it? Power or sub station
failure, breakdown in the distrrbution nerwork, or simply a pulg
being pulled out accidentally.
Power-back surges: These typocally occur when power returns after a
power-cutand connected equipment receices a surge of electricity at
an over-voltage level, which can be cery damaging(see above). What
causes it? Power back surges are created by the utility, when it
restores supply at an above normal voltage in order to compensate
for the demand as connected equipment re-starts simultaneously.
Telecom surge, spikes and lightning: Short term, high coltage and
current phenomena occurring on the teleghone lines, Can cause
irreparable damage to any piece of equipment connected to the
incoming line, the telphone line itsdlf may even be damaged or
destroted in sevre cases. What causes it? Telecom spikes are caused
bu lightning striking either the telephone linge directly or an
object near it.&
