Suggest A Voltage Stabilizer

Dear All,
Please suggest a suitable voltage stabilizer for the following setup.
Onkyo HT-SR800 (670W)
Onkyo Powered Sub-Wooofer (140W)
I will be connecting tatasky stb, lg-dvd player and a worldspace apart from the onkyo stuff. I will not be connecting the tv as it has the feature built in and an additional one is not recommended by the manufacturer.
I had zeroed in on V-Guard DIGI 200 model but is not in stock in Bangalore.
Please suggest a model at the earliest.

Hi Ram,

The Voltage Stabilizer that you have short-listed i.e. the V-Guard Digi 200 is an excellent choice. Well the V-Guard warehouse is located in Mission Road (on the adjacent lane next to Indian Oil Corporation corporate office) where I am sure you would get one bcoz I used to buy here regularly for my customers. You can also contact me if you need further assistance (My contact no. is 9844404269).

I would like to express two points which I felt that I should share with you ...

1) Ensure that while connecting a sub-woofer to an Volt/Stab the sub-woofer dosen't overload the Volt/Stab i.e., the output capacity (VA) of the Volt/Stab should be good enough to withstand the load of all the equipments that you are connecting. For various reasons, I personally suggest that you connect the sub-woofer to the raw power instead to an Voltage Stabilizer.

2) To my knowledge, generally the power section of any television has only basic protection at the primary stage (230V AC) and a proper power regulation circuit only at the secondary stage (low voltage output). So you cannot expect a complete role of an Volt/Stab from a built-in circuit of a television. In that case why many leading Volt/Stab manufacturers still continue to manufacture separate Volt/Stabs for Televisions? I personally suggest that you use an Volt/Stab for your television so that it gets complete protection from Surges, Spikes & Over/Under voltage problems.

Hi,

Ideal stabilizer for you should a 1.5 or 2 kva one ! if budget permits try to go for servo ( though not good one's available) I think Anil knows some places where you can get a decent servo stabilizer.

I don't know the spec of this digi200,but recon since it says 200 its a 2kva ( Am sure it cannot be 200Va) and should be good enough !!

Just give it thought and decide !!


Regards.

A servo is a better option as it gives a more constant output voltage than a voltage stabilizer and offers faster response to fluctuations. Most of these on their own will not provide protection for surges, spikes, etc. For that you could use a good quality surge suppressor strip. 1.5 Kva should be sufficient for your given load.

Would a UPS work well here?
Connect the electronics (amp/receiver/player/STB) through the UPS and the sub through a regular voltage stabilizer?

Ram mohan,

What is the Ampere spec of this DIGI 200 and how many o/p sockets ?
I think you should look at the Power consumption of your equipments if you plan to connect all to one stabilizer.

Dear All,
Thanks to all who have advised me and for their suggestions.
I have managed to locate the availability. Its also available at Modern World apart from Sonovision. I have chosen Modern World as its closer to my wife's workplace.
Its a 6 amp rated stabilzer. i.e, its a 220*6 = 1320W model. I am not very sure of the power factor to be applied (for the type of equipment-Home theatre, Sub woofer, Tatasky STB, and DVD player). upon considering a power factor of 0.75, the VA rating of the model comes to 990VA (1 KVA). The AVR and Sub Woofer are rated at 670 and 140 respectively. This adds to 810W. Add another 10 + 10W for STB and the DVD player. This comes to 830W. This is less that 1320W. From this basic calculation, it looks like 1kva model is sufficient. In fact the people at Modern World even suggested that I can go for a 3 amp model. I did not want to take a chance and would be settling for the 6amp model.
I hope that I am correct with the calculations. Any advice on this would be highly appreciated.
Regards

Ordinary (economy)UPS provides a stepped Sine wave , use of this type of waveform is harmful to your audio gears. You must use a A pure sine wave UPS which is very expensive further Amp/receiver has got high inrush current during start up and while reproducing some complex / dynamic / high energy music , so UPS rating must be much higher than steady state requirements, consider this while deciding on VA ratings of the UPS. This translates into a very expensive UPS perhaps costing more than your entire setup.

Any economy grade (cheap) voltage stab, servo, isolation transformer, power conditioner, surge suppresser etc will serve nothing . It will give you a false sense of security and nothing else .

Further anything between AC mains and audio gear will some way or other affect the performance .

I am against of putting anything between your AC mains and the system. But if at all you are so determined then you can consider Audiophile grade Power Conditioner / Re-generators made by PS Audio (USA) , but these products are way expensive (Rs 200K+)!

Hope this helps

Hi, Buy a good one, this is much better than v guard. 2 kva stabilizer should be ideal, cost may be on the higher side but this is a excellent option. Buy Vertex stabilizer, sold by Mr. Manjunath, contact # 9886081610.
