Just note that double conversion means that it is very noisy so make sure it's outside the listening area.
That would be a problem. My dedicated line terminates near the systemJust note that double conversion means that it is very noisy so make sure it's outside the listening area.
Online double conversion online is one of the best solutions if you can place the UPS away as the there is fan noise. APC,Eaton or equivalent also have fan noise that is audible.Else servo ...note that servo also make a low grunt noise when the voltage fluctuates !Vivek, the idea is indeed good quality power. Without specifics, servo stabilizers are analogous in voltage correction. That is why they are sought after as relatively inexpensive but very apt solution for hi-fi needs. Your equipment would equally get hurt with sudden voltage correction as with sudden voltage drop. As mentioned, Vertex also adds an EMI filter and that is why it is so popular in the hifivision circuit.
My suggestion would be to always go for a pure sine-wave online UPS. The double conversion aspect takes care of noise, surge, isolation, fluctuation, pure sine wave, brown outs, black outs and lot of other concerns that I do not understand!
I am not a power electronics guy but that is what I understood from this very useful thread when I was deciding for myself. Read it when you have time.
POWER GAMES:Servo Stabilizer,CVT or Online UPS?
Today I began exploring options for providing safe,uniform power and protection to my cdp/pre/power amp.Everytime I press the crazy membrane switch of the Bryston 4B SST,I am mortally scared that the twin green lights will not come on.And when it powers on,I heave a sigh of...www.hifivision.com
Hi
Today I went to my local APC dealer who sells servo stabilizers as well. What I have read
on the net and suggested by many fellow members here, an online UPS should be better than the servo stabilizer. My reasoning for this is that online UPS always converts ac to dc and again to ac and this should be more cleaner than the direct outflow from servo.
My current load is an amp plus dac which is around 350 watts. I plan to add a streamer, tuner and could be a cd player but not that soon. This will still be less than 700 watts.
I am inclined towards 1kva/800 watts APC online UPS costing around 24k, with 2 years warranty on both ups and batteries. After that Rs.4400 per year AMC that covers everything but that is optional.
I was told that the APC comes with EMI/RF filters? This I need to confirm from specs.
Is it good to go?
P.S. The price of 5kva servo is around 14k without any filters. The dealer also suggested to go with online UPS. The 2 or 3 kva APC online UPS costs nearly 34k.
Thanks.
In terms of online double conversion iam using APC 1KVA SRC1KI-IN ; most expensive ; has indian type output sockets ; great build quality . Eaton has IEC output sockets . I was using Noida based importer /mfr >BPE -1kva -online double conv before (best power equip) .Performed very well but has a quirky interface ; cost effective.Also to their credit BPE answer emails sent to them . (Note : no affiliations)Hi Guys
Any word on Microtek/Luminous Online UPS.
My only inclination towards online UPS is cleaner power over offline one.Online UPS is primarily required for Network equipment which is sensitive to switch over time. For AV equipment any Offline UPS (Preferably APC) with a switch over time less than 5ms should do the trick. I hooked up all my AV equipment (TV+AVR+Sub+Streaming Device) to BR1000G-IN, and this set-up is working like a charm.
True. I have kept mine in an adjacent room.Just note that double conversion means that it is very noisy so make sure it's outside the listening area.

This is kind a surprise to me that an online UPS make that much noise that its a disturbance. How much noise it makes, more than a fan?Yes. Online is definitely better. I have tried both (Online and Offline UPS) and found the SQ is better when powered by online UPS. But beware of the noise. You might want to keep that in another room or so...
Agreed. The noise is at 53db so loud enough to hear across any room. I shifted mine to outside the house.Quite a bit that you will definitely want to put it in another room...
I already have a dedicated line. You mean CVT power rating is twice the load of all equipment? If so.then why so is required?I would suggest a CVT with isolation is good enough. Ensure that the power rating is twice the load.
Draw a line for audio off the mains if possible
Especially when you have high powered amps and active subs, twice the capacity would ensure dynamics are not affected during heavy passages. Though the technical recommendation is around 25 to 35% than the total load, amps can draw quite a bit.I already have a dedicated line. You mean CVT power rating is twice the load of all equipment? If so.then why so is required?
I read through this. It just shuts down in case of voltage surge but won't correct the voltage. That's my main concern.If you want a best in class device, the other option is a power conditioner. No backup but excellent power conditioner.
