The
AVR meaning
AVR is an abbreviation for Automatic
Voltage Regulator. An AVR is the
equipment that regulates the voltage
to the safe range for the connected
electrical and electronic loads,
and improves power quality as well.
It protects the loads from taking
too much power from unstable power
source such as voltage fluctuations,
sags, surges and electrical noise,
etc.
The difference between AVR and UPS
is the AVR cannot store backup power,
its cost is much lower and be only
used to some electrical loads.
There
are two main functions of AVR as
the following.
•
Automatically
regulates the voltage to
the constant range for safe
application
•
Improves
the power quality as well
by filtering and suppressing
unwanted disturbances
The
AVR functions The AVR
or Automatic Voltage Regulator uses
the microprocessor to control its
working that modifies the sine wave
to an optimal wave shape, which
means that the voltage is constant.
It combines the automatic voltage
regulation system so that can regulate
the voltage to the constant range
by adjusting the incoming power
up or down within capable of its
control. Inclusively, an overvoltage
or voltage drop protection circuit
to disconnect the utility power
supply if the total of voltage is
out of range, and then restores
it automatically once incoming power
returns to a safe range. Moreover,
it has an overload and short circuit
protection, electrical noise filtering,
such as Electro-Magnetic Interference;
EMI and Radio Frequency Interference;
RFI, etc. and surge protection.
The
AVR advantages
The AVR or Automatic Voltage Regulator
can handle many problems such as
transient, voltage fluctuation,
variations in voltage, surge, spike
and electrical noise caused by the
unstable utility power supply, etc.
The AVR monitors, regulates the
incoming utility power and suppresses
the unwanted disturbances before
supplying power to all connected
loads.
The
AVR applications
Since the main function of AVR is
to regulate the incoming utility
power, therefore, it is an necessary
equipment for any applications that
are sensitive to power variations,
use for critical application in
remote area where consistent voltage
range cannot be trusted and Service
call applications. At the same time,
the AVR consists of the high efficient
microprocessor, which enhances the
AVR features as high functions,
high reliabilities, user friendly
and easy to maintenance. The AVR
is compatible with all electrical
equipments, which need to regulate
the voltage to be constant, but
they must not have any effects and
damages if blackout occurs. If the
AVR is used to the computer, it
cannot supply the backup power like
the UPS.
