Voltage Stabilizer

    A voltage stabilizer is an electric device that uses continuous electrical equipment such as AC and computer and protects them against damages due to voltage fluctuations. It works on the transformer principle, where the current is connected to the primary winding and the output is made from the secondary winding. 
     When the incoming voltage decreases, it activates the electromagnetic relay, which adds a higher turn in the secondary curve, thus providing a high voltage that compensates the loss in the output voltage.

    When the incoming voltage increases, it is reversed, and, thus, the voltage in the output side remains almost unchanged. It is an electrical device that is designed to give continuous voltage for the load on its output terminal. It protects the device or machine under voltage, voltage, and other voltage surges.

It is also called an automatic voltage regulator (AVR). Priority is given to expensive and valuable electrical appliances to protect voltage stabilizers from harmful low/high voltage fluctuation. Some of these devices are air conditioners, offset printing machines, laboratory equipment, industrial machines, and medical devices.

What you do today depends on your electronic devices; Even if you have a mobile phone, your television or gaming console, electronic devices make their everyday lives easier because it makes them really important to keep them safe. You need to keep your equipment safe but not from electricity

The electronic devices you are using are usually sensitive. They need the correct voltage to work if the voltage is unstable, your device will be damaged. Vortex instability occurs due to technical failure due to a sudden increase or decrease in your sensitive electronic devices. In addition, serious damage to the equipment due to severe electrical spikes and serge seriously

Electricity equipment is much weaker than electricity, so steps must be taken. Electric appliances make your life comfortable, these tools can cost you a lot less, so be sure to test your products.

How to Select a Suitable Stabilizer for Home Needs?

    Voltage stabilizer depends on the rating of the equipment for size stability, so during the purchase of voltage stabilizer, the first and foremost thing is that the strength of all the devices (or a special device) that will be supplied by the stabilizer, such power ratings are usually VA Is quoted in or KVA.

    Also, need to consider Power ratings of the device; If the power rating is not available then just calculate the voltage product and calculate the current of that power rating. It is always recommended to consider the correct RMS voltage of the load. 
    Another major factor is to consider expanding the future of load. So to determine the total power rating, potential future expansions are required, usually, 20% more than actual power requirement For home needs, 200VA, 300VA, 500VA, 1KVA, 2KVA, 3KVA, 4KVA, 5KVA, 8KVA, and 10KVA rated voltage stabilizers are appropriate. For industrial and commercial purposes, high power rated servo stabilizer is required
  • Before the voltage stabilizer can be loaded into the load, the fluctuations can control the input voltage (or devices that are sensitive to voltage variables). Output voltage input from the stabilizer within the given voltage range of the phase voltage, in case of three phase supply, the single phase supply will be in the range of 220V or 230V in case of 380V or 400V. This regulation is done by the internal circuitry.

Why Voltage Stabilizers Are Needed?

    Usually, on the basis of input voltage sensitivity, the operating range of the devices is limited to a specific value, for example, some devices may bear ± 10 percent of the rated voltage while the other ± 5 percent or less. 
     Voltage fluctuation (the rise or dip of the magnitude of the rated voltage) is quite common in many areas, especially in the finished lines. The most common reasons for voltage fluctuation are shutting down the light, electrical defects, defective wires, and devices periodically. These fluctuations cause accidents for electrical appliances or appliances

Long time overvoltage will result

  • Permanent damage to equipment
  • Insulation losses for windings
  • Unwanted obstacles in load
  • Increased losses in cables and related equipment De-rating

Longtime under voltage will result

  • Bad process of equipment
  • Long Term Duration (In case of Resistant Heater)
  • Low performance of equipment
  • Attract large currents which cause excessive heat
  • Computational errors
  • Low speed of motors
So the voltage stability and accuracy voltage stabilizers ensure that the voltage fluctuations in incoming power supply do not affect load or electrical equipment.

Voltage Stabilizer

  • Increases the useful life of equipment;
  • Reduces the rate of the fault of the equipment;
  • Maintains a stable power supply;
  • Reduces noise, interference, and electricity;
  • Protects against under-voltage and main voltage;
  • Operates in cases of overload and extreme heat;
  • Events from the main signals
It is an efficient solution of moderate cost, which is recommended for those people who want to protect their oscillations from noise in the voltage, spikes, and noise. Compared to filtered, protected and stable power supply, there is nothing more important for electronic devices.
