Using AVRs The Proper Way

Wonder why AVRs sometimes malfunction? We can say that mechanical devices are not that perfect, but have you ever thought you might be using it the wrong way?

AVR (Automatic Voltage Regulator) is a protective electrical device that is designed to protect equipments from volltage fluctuations as it automatically controls the voltage being supplied to certain equipment.

AVRs in the Philippines

Here in the Philippines, voltage spikes happen frequently and we cannot deny it.  Most of us are confident when using an AVR for our TVs, washing machines, and refrigerators since it’s made for the said purpose.

 

What we don’t realize is that any mechanical device that is used improperly or abused to its capacity will definitely result into malfunction or worse, great damages.

When you want to utilize an AVR with equipment that has a heating or cooling element, like a fridge or an oven, it is advisable to use an AVR that is three times higher than the equipment’s power rating as it consumes higher initial current to alter normal temperature to the required coolness or hotness. Let’s say you have an Aircon unit with a power rating of 1000 watts. To comply with it, you have to use a 3000 watts AVR or higher since it converts normal air temperature into a cooler breeze. In this way, your aircon unit will be safer even with continuous necessity of high power consumption.

Similarly, motor operated appliances like washing machines and heaters need to be associated with AVR that is three to five times higher than the machine’s power rating. Motor operated machines usually consume higher initial current the moment the machine is switched on or sudden voltage fluctuation happen. Voltage fluctuations are voltage which frequently vary, rise and fall from the steady or repetitive value. By the use of a precise wattage of AVR, spikes will be handled appropriately while the machine continues to function.

For non-motor-operated machines and equipment that has no cooling or heating element, AVR must be commensurate or higher with its specific wattage. For an instance you have a PC unit rated at 200 watts plus a speaker with 100 watts and a flat screen TV of 300 watts all plugged into one AVR. Summing it all up, you’ll get 600 watts. In this case, you can use 1000 watts AVR as no motor, heat or cooling element involved. It’s good to have a little bit of allowance in case of a power surge.

One improper way of using an AVR is when plugging appliances to any voltage output socket. This is fatal for the attached machine! Plug the appliances with the right voltage requirement to the corresponding voltage output socket. For a fridge that requires 110V power, plug it into the AVR’s 110V output socket. With this, the right working voltage will be supplied to the fridge .

All mechanical devices have a certain limitation depending on how we use them. With AVRs, its best to follow certain advice from expert technician or from the electrical supplier where you purchase the device to properly protect the equipment you have. And most importantly, choose a brand that brings the best quality products and services.

Choose quality, choose excellence! Choose Meiji Electric!

    Hello,

    Can I plug in my 120v onkyo home theater receiver to a 110 AVR?

    Thanks

  2. Ditas says:

    What can happen if I use a 1000w AVR for a non-inverter 1000w refrigerator?

    • John says:

      If you’re using a 1000watts appliance you need at least 3000watts for your safety.

      Note that if you use AVR with same wattage of your appliance it might damage the AVR or the appliance.

      Please consult your technician/electrical engr for recommendation of appropriate avr for your refrigerator.

      Thanks

    If Im using a 1500 watts ice cream machine how many watts of AVR I need to use

    • John says:

      Hi Nino!

      Thank you for inquiring with us.

      Regarding appropriate AVR for appliance/equipment, we suggest to consult to your electrical engr or electrician. Usually we recommend to triple the wattage of your appliance but there are cases that triple is not enough.

      Thanks

    My washing machine is rated at a Max wattage of 2100W, I am considering AVR: SVC-3000W, with the excess 900W (3000W – 2100W) that should be enough right ?

    • John says:

      Hi Henrick,

      Our recommendation for choosing an AVR is to double or triple the wattage of your appliance for your safety. 3000watts might not enough, you can consult to your electrician so they can check the appliance for appropriate wattage of AVR.

      Thank you

    For my 2hp motor sir. what is the exact watts of AVR that I use. This motor operate for 10 hrs a day.

    • Meiji Admin says:

      Hello Tonie,
      Our recommendation for choosing an AVR is to triple the wattage of your appliance for your safety purposes. you can consult to your electrician so they can check the appliance for appropriate wattage of AVR.

    Hi.

    I have an induction cooker with 2000 watts. What wattage of avr do I need to use?

    • HenryMeiji says:

      Hello Fred,
      we can advice you to use an AVR that is triple the wattage of your appliance to ensure the safety of your appliances. you can also consult to your electrician so they can check your appliance for right wattage of AVR.

    • Yvivy says:

      if my aircon is 230V, 535W(power input), will the 3000W, 300V MaxTech AVR be enough? Thank you 🙂

  7. Yvivy says:

    what does it mean when there’s a sudden loud clicking sound? is it normal or should i be alarmed?

    • HenryMeiji says:

      hello yvivy, its totally normal for the AVR to have a Beeping, Clicking or Mechanical sound, it is due the the AVR adjusting to your Appliance’s Voltage.

  8. Miel says:

    Good day.

    asking if I have a mini refrigerator (for my bedroom) 90 Watts and I have an AVR with 500 watts
    I experienced a beep sounds in my AVR when my ref reached the temp of the thermostat then the ref will cool down. After that another beep sound when my ref works again.

    Is this okay?

    • HenryMeiji says:

      Miel, its totally normal for the AVR to make beep sounds & sometimes some mechanical sounds, it is adjusting depending on the voltage of your appliances.

    Can I plug an AVR to an extension?

    • Niel says:

      Hi,
      Can I plug an 500VA Power AVR to an 15A 250V~ Extension Cord? I don’t know much about electronics, I’m sorry If it lack information. Thanks!

      • HenryMeiji says:

        Hello Niel, Its better to plug your AVR directly to an outlet, its risky to plug it on the extension set because if it breaks it might also affect the AVR.

  10. Levi says:

    Hi my avr does not display the correct voltage of my refrigerator but it works perfectly fine before a 2 weeks lost of electricity. May I ask what is the problem? Thank you

    • HenryMeiji says:

      Hello Levi, we can’t really say what the cause of the problem, maybe its better if you call us on our office so you can explain to us in detail. thank you!

      Hello Nathaniel, you can check the wattage of your appliance, you should use atleast 3X the wattage of your unit to the AVR you’re using.

  13. Alexis says:

    Why does my AVR show 110v output instead of 120v ? My power conditioner shows 120v. Does the AVR need adjustment ?

  14. Irvin says:

    How much does 1000 watts AVR consumption?

    • HenryMeiji says:

      Hello sir, our AVR doesn’t consume electricity when nothing is plug in to it, maybe a little for avr to energized but it all depend on how many watts your appliance consume when it plugs into it. hope this helps.

    Is it okay to plug in two computers to 1 meiji svc1000? just computers no monitors and anything else.

    • HenryMeiji says:

      hello sir, you can check the wattage of your computer. you can use at least 3X of the total wattage of your computer to the AVR you are using. Thank you hope this helps

  16. Angie Corre says:

    Good day MeijiElectric PH! May I ask how many AVR watts do I have to buy if I have a refrigerator that’s equal to 230V or 550W power rating? I would like to make sure before I purchase. Thank you for your response!

    • HenryMeiji says:

      Hello Angie, for the AVR, you should check the wattage of your appliance, you should use atleast 3x of your appliance wattage to the AVR you are going to use, also check the output voltage if it compatible with your unit.
