Buying a Stabilizer for my LED. Need you help!

[maverickgenius]

**I already posted this but the thread doesn't seem to be created. So re-posting this**

Hi,

I am gonna buy a stabilizer for my 32 inches Samsung UA32D4000 LED TV. I looked through all the threads here but still couldn't conclude what to opt for.

I am a novice when it comes to electrical so I need your help on this. I had a look at V-Guard digital stabilizers and can't decide what to choose. The Samsung guy who installed it said I need 1KVA but V-Guard stabilizers come with Ampere rating.

Here are the list of V-Guard products:

I am thinking of going with the VG Crystal one which comes to 0.762 KVA. Would it be sufficient for my setup? I will connect the TV and my airtel DTH set top box.

Any help on this is really appriciated.

Thanks!

For connecting a TV and DTH STB, you don't need 1KV stabilizer. The V-Guard Crystal you selected is enough for your use. 0.7KVA can handle a load of around 400W. Your TV and DTH will hardly total 100W. You can also use a 600VA UPS. This will give you better protection than a stabilizer IMHO.

Is it recommended to buy a stabalizer along with a TV today? Bangalore does not witness power fluctuation but power outage once/twice a day is common.

 

[aakashr]

ensure the stab is a sine wave or modified sine wave..............better protection for your devices.

Thanks for the quick responses.

baijuxavior: I heard that a stabilizer is better is protecting from fluctuating voltages than UPS.

And I forgot to mention, the TV is plugged into the mains which is connected to an inverter. Does this have any impact on using a stabilizer?

Even I was looking for a stabilizer for my 46" LED TV and Airtel DTH box and Home Theater.

^^If you add a HT, then a 1KV or higher is recommended. My preference would be for an online sinewave ups but it is very expensive. Instead of normal 'offline' computer ups, I am using a 1.2KV line interactive ups. It has a built in stabilizer which will work from 130V to 290V. This makes sure that your battery is used only rarely. The output is sinewave when on mains mode, but quasi sinewave when the ups changes to battery mode.

Check out the V-Guard DIGI-200. Price: <5K. The capacity of this model is 2KVA (Approx. 1600 watts). The following equipments can be connected.

Any size of LCD/LED/Plasma TV
AV Receiver
Blu-Ray/DVD player
Cable TV Set-Top box

As per the manufacturer (V-Guard), this is a digital circuit based stabilizer with surge/spike protection feature and it is specifically designed for audio/video and medical equipments.

I just bought the mini-crystal model from V-Guard since the shop didn't have the next higher model. Can you please let me know if this will suffice for my LED TV? What load can it take?

Also, the stabilizer has two output sockets. Is it advisable to connect my set top box also to it? Can it handle the load?

Thanks for all the replies guys!

 

[baijuxavior]

It is .5KVA (~ 300W) stab and it will handle both your tv and stb with ease. No need to worry.

baiju: Thanks again for the clarification.

I earlier had another question: The Stabilizer is not connected to the mains which is connected to an inverter.
(ie) Inverter -> Mains -> Stabilizer -> TV.

Incase power goes off, the inverter takes over.

Will this create any problems?

 

[baijuxavior]

You should not connect stabilizer to the out of inverter. Use either inverter or stabilizer one at time. If your stabilizer has enough power to handle the inverter load, you can connect inverter to the stabilizer out. But in your case the stab is just 500VA and connecting inverter to stab out is not recommended. For example I have connected my 1.2KVA UPS to a 5KVA servo stab and it is fine, but not the other way.

This is a noob question so my apologies if this sounds too obvious.

I bought a Samsung 43 inch plasma and I am wondering now if a stabilizer is required? We face electricity cuts during the day once or twice, don't really have power fluctuations. Another point to note is that I do not have a general UPS in the house. I also have a basic cable box and a sound system that I have not yet hooked up.

Is a stabilizer recommended or should I buy a UPS for the TV? I saw this on Flipkart for example.

Thanks for all the help. I have learnt a lot here.

Hi All,

Recently I bought Yamaha YHT-196 Home theator system and i am planning to buy a new stabilizer and these are all the equipment i would connect in

42' LG LED TV
LG Blueray player
Yamaha YHT-196 Home theator system

currently i am using vg mini crystal and i believe its not sufficient to go with all the 3 equipment at once.

so can some one suggest me which stabilizer i can go with would help me to keep my mind in peace from power fluctuations ..

thanks in advance.

Hello All,
Need suggestion
Is stabilizer necessary ? we do not face power failure in our area, may be once or twice in a month.
Just wanted to know, as I will be buying a new TV.

I will be connecting my Airtel DTH, TV & DVD player.

Hi,

At my home we have Inverter and yes lot of power cuts during summer.

Inverter powers 3 sections of my home.
TV is connected in one of those sections.

I am going to buy LED Tv, so do I need to buy any additional UPS/Stabilizer for this?
Since Inverter will turn on during power cuts automatically, is there any extra care that I should take care in-case of TV [Expensive gizmo ]

I bought a V-Guard voltage stabilizer for the sake of my LCD TV, STB, Amp & Turntable and the projector (at times) that I have and run from the same outlet. I think it costed about 1850 bucks sometime in the last year. The protection lets you have confidence in case of a spike or just high voltage. Fluctuations, if any are also taken care of. I would say go ahead and invest in such a device.

Wanted to ask a question: Can I use a UPS to power my LED projector? The projector has a separate laptop style power adapter that I want to plug into the UPS to take care during the power cuts. The UPS, obviously is not a Sine wave UPS and an ordinary computer UPS.

Few months before i had a normal power cut in my house and my led tv samsung ua32d5000 would not power on just blinking red led light........called up samsung....the technician told me that the tvs pcb and main board both have got damaged.......i had to buy a new pcb and board costed 6000+ fitting charges extra as it was out of warranty...the guy suggested to put a surge protector or spike guard or something......dont know what its called....so better to put a stabliser i guess rather than to risk appliances

I observe that a number of products are getting mixed up for their functions in the above discussion.
Just to clarify the following are the requirements for most of us.

1) A surge / spike protector - this is essential and protects from transient spikes. A transient spike is surge in voltage for a fraction of second. A voltage stablizer or a normal UPS alone will not give protection against these kind of spikes and will allow these surges to pass through thereby damaging the equipment. FM hifipal4all has suggested a Digital stablizer for spike protection in the above post. I have been using this for the past 4 years with out any problems as this provides surge protection also. Note that I connect my equipment to genset out put also through this digital stab despite many people recommending against it

2) a stablizer is required mostly when your incoming voltage falls below 200 v or so . Most present day TV s accept a wide range of input voltages typically from 180 v to 250 v - hence a stand alone stablizer is really not required unless it has other accompanying protection like spike buster etc.

3) most low cost ups will pass through the incoming voltage with out any conditioning and hence is not a protection.
You will need an online ups for true protection.

Finally if any of you are using inverters ensure that you are using pure sine wave inverters as opposed to the cheaper variety which may out put a square wave
