Which are the best voltage stabilizers
What is the voltage stabilizer?
It's simple, a device that stabilizes the mains voltage.
Normally The network voltage should be 230V, But it's never like that.
The day, when the world uses energy intensely, tension can decrease.
At night when the world is asleep, tension may increase.
That's what happened to me, where the day I have 220-230 volts, and the night 260-270 volts.
We complain to your energy provider!
That's what I did, and indeed the boys came.
When they measured, as normal day came, the tension was normal.
In the contract with the energy provider he writes that a +/- 10% deviation is allowed.
That means (according to their mind) that it is OK to have the voltage between 207 and 253 volts.
Of course I also paid for their intervention, and for me nothing has been solved.
I got my stabilizer
After years of throwing a bunch of electronics into the trash, as I was burned by the current, I decided to buy a stabilizer.
I bought a stabilizer with a servo motor, because that's good for refrigerator, air conditioning, microwave, etc, motoring stuff.
Which stabilizer to take with relays or servo motors?
Types of stabilizers on the market:
Relay Stabilizers
They are suitable for any kind of electronics: TV, computer, radio, bulbs, laptop, etc. This type of stabilizer is found in any size and has some advantages.
Advantages Relay Stabilizer:
1. Small dimensions
2. Cheap
3. Fast on network voltage changes
Relay Stabilizers Disadvantages
1. It does not work well with motorized devices
2. Most do not have pure sinusoidal waves
3. They can be loud because of the fan at high power
4. Less efficient than servomotors
Servo motor stabilizers
They are perfect for any task, especially for voltage stabilization for motorized devices
If you want to stabilize the voltage for: refrigerator, air conditioner, water pump, freezer, microwave, then a servo motor stabilizer is perfect.
Advantages of stabilizer with servo motor
1. They have a pure sinusoidal wave
2. It works with any kind of electrical or household appliances
3. They are very efficient, efficiency over 97-98%
4. They are relatively silent, they hear from time to time a little flick of the brush
Motorized servo stabilizing disadvantages
1. They are bigger and heavier
2. They're a little more expensive
3. They are not so fast at high voltages (the problem solved)
How to check the power and what it means 1000VA (volt amp)
Super simple, you will look into the specifications of the power factor and multiply it by these volts.
Example:
Power factor = 0.6
Stabilizer power = 1000VA
Then we make 1000 x 0.6 = 600W
That is, you can put 600W on the 1000VA stabilizer

Servomotor stabilizers are noisier because the rheostat motor that regulates the voltage is constantly heard. If you locate the stabilizer with servomotor in an annex, it will not matter too much, if you keep it in the room to protect the computer, TV, etc. in that room you will not be able to sleep :)
Pure sinusoid has nothing to do with voltage stabilizers, the sinusoid problem is only with computer or boiler UPS, which converts voltage from 12 or 24 volt DC batteries into 220 volt AC.
Relay Stabilizers are the quietest, I recommend them for electronic: TV, computer and other expensive electronics, located next to the device. There is a wall-mounted panel version.
For motors (pumps, fans etc) and bigger power in general, better ones are with servomotor.
Servomotor stabilizers are typically used for high power, with one of 10-20 KW powering your entire house, those with lower power relay up to 2500 VA.
At the same power the servomotor is at least 1.5 or more expensive.
It is absurd to have a 2-3000 lei or even 2-3000 euro installation and do not protect it with a 2-300 lighter stabilizer.
Although I no longer work in the field, I strongly recommend the Well stabilizers.
If the SVN 2000 servomotor stabilizer / 1500w Trivas with two outputs can connect the boiler and combine the refrigerator. In his book he says that the * delay * function is used for consumers with a compressor (air-conditioning or refrigerator), so the rest of the consumers do not use the function.
Excellent! Clearly, as for all man. From you I learned almost everything I know about
electrical, electronic, software and hardware. Respect to all and I wish you "long and prosperous life"!
"long and prosperous life" quoted from the star trek somehow?
Hi Cristi
I am subscribed to videotutorial.ro and I appreciate the work you are doing for us!
Because I am somewhat familiar with the subject of this tutorial I would have a question: What can I find in the trade for FUNCTIONAL FUNCTIONAL FUNCTION of an audio system with RADIO -DVD AND USB AUTO in the house at the home outlet of 220V and especially on amperajull Thank you!
A phone charger with higher amperage, because the device draws its current exactly as it needs.
Good evening
What do you think about this type of stabilizer,https://www.emag.ro/stabilizator-de-tensiune-electropower-ep-svc-3000va-2400w-servomotor-cp-svc-3000va/pd/D7M3RMBBM/
I want to use it for a washing machine, a fridge
Cristi, a little bit of what you need. He would carry the washing machine, provided the heating of the water with the refrigerator compressor is not started at the same time, if they start all at once, you can pass 2400W.
Ok thank you, I think I will choose one of 4000w for 150 RON more I think it's worth it
a wonderful evening
For the boiler, what type is recommended?
Thank you.
With servo.
Thank you!
Hello everybody, if I use a PC UPS and other small box-type chargers, I would have to have a stabilizer, as it says on its page, it https://m.emag.ro/ups-njoy-isis-2000l-2000va-1200w-lcd-display-reglaj-automat-al-tensiunii-pwup-li200is-az01b/pd/DWZ3WBBBM/ contains something like that.
Yes, we want to buy one and we have found a good offer on this power-electric site but we are still in search. Anyway, thanks to this article, you've taught me something. Thanks for tips!
Hi, I still did not understand how I calculate what stabilizer to put, why capacity.
I need for the refrigerator combination with 2 engine compressors and a Vaillant 24Kw thermal power plant at the 3 room.
The plant thinks 200wati, I hope I do not get it wrong but combine it with 2 compressors I know it's more at the start.
