Best V-Guard Voltage Stabilizer Online in India – Reviews

Home Appliances

Voltage fluctuations and frequent power cuts
are common in Indian households. Here’s why we've listed the top 10 voltage
stabilizers for ACs, inverter and washing machines that you can buy online
easily without any hassles. Voltage stabilizer helps you prevent damage that
happens with voltage fluctuations. It's highly important that you smartly
choose the right one for yourself and your household. There is no best time than
ever to invest in the one since summers have kicked in.

A voltage stabilizer is a device that,
starting from the mains voltage, allows maintaining a stabilized supply
voltage, even when the input voltage is higher or lower of normal.

Apart from the technology, which we will see
below, there are two parameters that best define a stabilizer: its power and
its precision:

  • Maximum power: is the maximum power value that can be consumed by the equipment that is connected to the stabilizer. Depending on the technology of the stabilizer, it is possible that we can exceed this value on time. In any case, the real sustained power of the connected equipment must be less than this value.
  • Accuracy: the accuracy with which the output voltage stabilizes. It is usually expressed as a percentage (+ -5%), so that the lower the percentage, the better the approximation of the output voltage to the nominal value (usual).


Not all voltage stabilizers work in the same
way. According to its technology, its main characteristics will be different:

  • Electronic Stabilizers or AVR (Automatic Voltage
    Regulator). They are based on the use of an autotransformer with several
    work points between which it switches according to the input voltage. Its
    principle is the same as that of the stabilizer that assembles an in-line
    UPS. They usually have three working modes: normal (the output voltage is
    the same as that of the input), boost (when the input voltage is low, the
    output voltage is increased) and buck (when the input voltage is high, the
    output voltage is reduced). They are the most economical and their
    accuracy is low; typically around 10-12%. Their response times are fast
    (less than 20ms) and by using an autotransformer they have the added
    benefit of filtering medium and high-frequency noise, as well as trimming
    transient surges.
  • Electromechanical stabilizers. They are based on the
    use of a continuously variable autotransformer on which a brush driven by
    a servomotor is positioned. Its accuracy is much greater than that of an
    electronic stabilizer, with its typical value being less than 4%. Its
    speed of response is slower and depends on the speed of the servomotor,
    which will respond faster to small variations and more slowly to large
    variations in the input voltage. Like electronic stabilizers, they filter
    noise and trim transient peaks.
  • Solid state stabilizers. Unlike their cousin’s
    electronic stabilizers, they use TRIAC to make commutations and usually
    employ a greater number of work points. By not using mobile parts they are
    more reliable, although less robust when their maximum power is exceeded.
  • Ferro resonant stabilizers. They use a saturation
    transformer as a means to regulate the voltage. Thanks to the magnetic
    saturation property, these stabilizers are based on a resonant circuit
    that produces a very constant average output voltage. This type of
    stabilizers is very interesting because they have no active components or
    moving parts. They are the most robust and accurate. They also provide
    galvanic isolation between the entrance and the exit. In addition to a
    higher cost, its main drawbacks lie in its size, emission of an audible
    buzz and great heat dissipation. Their efficiency oscillates around 90%
    when they are used with high loads, but can be less than 60% with low
    loads. Due to the aforementioned characteristics, they are more typical of
    industrial environments than of homes or offices.

Why Stabilizer for your AC?

When it comes to the functioning, AC is quite intricate and requires constant power for the compressor and PCB modules at the same time. These modules are highly sensitive to voltage function. Roughly these components work perfectly between the 170V-270V range. Beyond this range, any voltage supply is significant damage to the quality of the compressor and PCB which are expensive.

When it comes to protecting sensitive or
expensive equipment, the best option is usually the most accurate stabilizers.
If these types of equipment are industrial and have high energy demands, we
will look for maximum robustness. If, on the other hand, we talk about
household equipment that is not particularly sensitive, it will be appropriate
to opt for a more economical option.

Let's see some examples:

  • The electronic stabilizers or AVR will make sense to
    protect equipment that is not very sensitive and does not generate high
    energy demands. In general, any electrical or electronic household appliance
    that does not exceed the maximum power can be protected with a stabilizer
    of this type. For example, televisions and AV equipment, small appliances,
    boilers, small pumps, etc.
  • Electromechanical stabilizers will make sense to
    protect more delicate equipment or those that generate high energy

In the computer environment, voltage
stabilizers are suitable to protect less critical peripherals and especially
laser printers. They are not suitable to protect computers or servers, because
the lack of batteries cannot guarantee electrical continuity in case of a total
failure in the supply.
