What an AVR Really Does For You

Last Updated on

Check out our entire list of available AVRs and order them straight to your home today!

Servo Motor AVRsAn AVR is located in more than one place in your home. You see it in the living room beside the Plasma TV, you see it in your room beside your desktop computer, and you see it in the kitchen beside the refrigerator. At the office, you see it in each working station beside their computers. It somehow became a general knowledge to buy it together with an appliance people value. And everyone also makes it a point to turn it on first before using the appliance plugged-into it. But what really is an AVR? And why spend more money to buy it after already purchasing a good quality appliance?

What are AVRs?

An Automatic Voltage Regulator is an electronic device or circuit that maintains an output voltage to be consistent to its load current. This is necessary because the voltage delivered to your home and mine may sometimes fluctuate which can cause serious damages to your appliance; if not completely destroying it. Fluctuations in power are brought about by so many factors. Some of these may be poor power regulations, electrical surges due to lightning, and many others. An AVR however, has a servomechanism inside that hunts the accurate voltage when surges happen in order to maintain the needed voltage level that ultimately protects your appliance.

Now you may ask, why not use an AVR in all my appliances? This friend may be a logical question but an impractical one. An AVR is usually necessary for appliances and equipments with electronic devices inside that may be sensitive to electrical surges. Examples of which are flat screen TV’s, audio/video equipments, computer systems, modern refrigerators and similar items. Simple home appliances that do not contain sensitive electronic devices like electric fans, blowers, portable radios, etc. do not need AVR’s.

In general, there are two types of an Automatic Voltage Regulator. One is the Relay Type and the other is the Servo Motor type. A Relay type AVR makes use of electronic circuitry like relays and semi-conductors to regulate the voltage. Servo Motor type AVR on the other hand, uses a magnetic core with a motorized servo mechanism to regulate the voltage. The servomechanism is the one responsible in switching connections in order to maintain the acceptable voltage. Durability wise, a Servo Motor type AVR is better than a Relay type as it can withstand voltage fluctuation better than the solid state Relay type which may easily get damaged.

Meiji supplies AVRs of complete wattages namely, 500, 1000, 1500, 2000, 3000, 5000 all in Servo Motor Type. The output consists of three 220V outlets and one 110V outlet. Meiji AVRs also provide you with an added protection of a delay feature of about 3-5 minutes in order to prevent electrical surges during the appliance’s initial power supply. However, for your convenience, a quick-start button feature is also available for you to bypass the delay feature.

All models of Meiji AVRs are fuse type. This is to protect users of the tendency of miscalculating load voltages being plugged-in to the AVR. In these occasions, the fuse will blow informing the user of an over voltage thus minimizing damage to the AVR and also to the appliance plugged-in. The user will only have to turn off the AVR, buy a replacement fuse from the available nearest hardware store, and switch back on Meiji AVR. And it works as good as new.

In addition to this, Meiji AVRs are very portable with handles that allow you to conveniently move the items to wherever locations necessary.

Aside from SVC-5000W, all models are ready-to-use. In Meiji AVRs, no need for you to assemble an outlet, a plug or a cord. In short, no added cost! For SVC-5000W however, due to its significant load and output, a qualified electrician/technician is necessary to safely install the load directly to the output terminals of the AVR by means of wires/cables.

For models SVC-3000W and SVC-5000W, Meiji AVR comes with a breaker. This breaker ‘trips’ or automatically turns off also in cases of over voltages that is too high to be accommodated by the fuse.

Now that you already know the importance of an AVR in your home, choose the AVR that can best protect your appliances/equipments.  Choose ‘Meiji’ AVRs!

    Why my AVR output is more than 220v? The pointer is in red line, so it’s somewhat 230v. Is is normal? Sometimes it comes back to 220v and sometimes back to 230v. Is my AVR defective?

  2. poor90skid says:

    mali intindi ko sa instructions. sinaksak ko yung 110v tv sa 110v ng avr, tapos bago ko isaksak yung avr,na-set ko siya sa 110v dun sa likod na switch. mukhang nasira. damay ba yung tv ko kahit di ko siya na-on? pwedi pa rin ba yung avr ko nun? di man basag yung fuse. pls help. 🙁

    • John says:

      Hi poor90skid,

      If it’s MEIJI Transformer please bring the AVR to our office so we can check the unit.

      Thank you

    Hi. What do you recommend for my US LCD TV with 192watts (120v X 1.6amps)? Thanks

    • John says:

      Hi Clarin,

      Please visit us at SM Acehardware so we can assist you.

      But we recommend to triple the rating of your appliance. Maybe 500watts transformer is okay.

      Thank you

    Hi pwede ba ang kitchenaide mixer 120v, 525watts?hm? san store available im from laguna.

    • John says:

      Hi Alyn,

      Please visit us at SM Acehardware, our sales personnel will assist you with your inquiry. Note that our recommendation is triple the rating of your appliance for your safety.

      Thank you

    I have 2 kitchen blenders – one is rated 750w and the other 1200w, pero both are both 110v, NOT 220v.

    I also have a 2000w AVR. Can I turn on both blenders if both are connected to the same AVR?

    Also, technical question – if 2000w is my AVR, what is the combination of wattage I can use for 110v and 220v gadgets?

    • John says:

      Hi Andrew,

      Please note that our recommendation is triple the rating of your appliance so our computation is WATTAGE OF APPLIANCE X 3 = RECOMMENDED WATTAGE OF AVR.

      It’s your risk if you want to use your 2000watts AVR for 2 blenders. The thing is it might damage the AVR or your blenders.

      Note that 110V output is for 110V appliance. Our AVR’s has 110V and 220V output.


  6. Rod says:

    How can i determine what capacity of AVR to use in our equipments? How can I compute for this?

    • John says:

      Hi Rod,

      Our recommendation is triple the rating of your appliance. So if your TV is 150watts x 3 = 450 (recommended wattage of AVR)

      Note that the higher the wattage the better and safer!

    I have waterpump in my pond consume 300watts in total running 24/7 ,I need this AVR , IS IT SAFE RUNNING 24/7 ??

    • John says:

      Hi Rock!

      Thank you for inquiring with us.

      Sorry but we don’t recommend our AVR to use for waterpumps, our AVR is designed for home appliances and small equipment. You will need a heavy duty AVR for your waterpump.

      Thank you

    Hi, quick question. I bought a TV Sony 40″ and what do you recommend AVR Watt and brand that I can use?

  10. Roberto Marcos says:

    Pwede ko ba gamitin ang 2000VA na AVR sa tatlong freezer? ang wattage ng freezer ay 350 watts.

    • John says:

      Hi Roberto,

      We don’t recommend to use 1 AVR for 3 freezers. For your safety use 1 AVR for 1 freezer. What type of freezer do you have?

  11. Romell says:

    Our neigbhor uses an electric motor that causes our lights to flicker and other appliances to run slow. Can your AVR help protect our appliances from those power fluctuations?

  12. Alvin says:

    I have 1 unit 2-HP aircon.

    How much is the minimum AVR watts should i put?

    Thank you.

    I have 0.5hp 110V AC, what can you recommend transformer for this equipment? It came from CANADA.

    Thank you

  15. MARIE says:

    what is the difference of Meiji Brand vs Chint Brand in terms of AVR 1000watts?

    • John says:

      Hi Marie,

      I’m sorry but I’m not familiar with Chint’s AVR.

      All I know is our brand can last long under normal operating conditions.

    Can a use the 110v output from Meiji SVC-1500 for a 100v Japan refrigerator?

  17. Eric says:

    Recommended wattage of AVR i will used for my 55inches Devant TV

  18. RON says:

    pwede po kaya ang 3 different appliances sa isang avr?
    we recently bought a tv with 170w, gaming console with 165w, and a black box with 12w, at plano po naming isaksak lahat sa isang avr

    • John says:

      Hi Ron,

      Use Meiji SVC-1000 watts for your 3 appliance. You can use 1 AVR for 3 appliances as long as the total wattage of equipment/appliance is within the capacity of AVR.


  19. Jayson says:

    Bakit po kaya madalas mag on and off yung isa naming avr? May sira po kaya yun?

  20. Eric says:

    I have 170 watts tv,what avr i can used?
