your system will perform better,last much longer and be saved from instant death that can occur for a number of reasons.

if you are protecting over $5,000 of audio equipment http://www.tripplite.com/products/up...martonline.cfm
comes with my highest recommendation.

what size you need depends on what your load is. they have a calculator at their website. the idea is not to run your gear off of that for any period of time. it is to shut off your equipment "gracefully" in case of a power outage spike/sag or critical ac power fault.

if you are not protecting over $5,000 of audio equipment i think the two units you picked out are fine line conditioners. they are very limited compared to what i just proposed. it depends on what is at stake and how valuable it is to you.

i want to point out that either the units you are looking at or a full blown on line ups are far superior to the expensive audiophile solutions in this market.

the same basic technology used in those less than $1,000 ups's i just pointed to is used by apc in million dollar power quality grids. those protect some of the most important equipment in the world. such as the internic and google.

in case you were intrested, that technology is called infrastruxure by apc.

a $100 ups will power a cheap home pc fine. consumer pc psu's have decent "stay up" and operate only as a class b device. they do not need super fast response or a true sine wave. however that type of ups is not compatible with any audio equipment period. not even a $100 receiver. as soon as that went to battery the audio device would be smoke.

if the on line is too expensive look at apc smartups. it is much more capable than what you suggested. for one thing it has real avr implementation. a simple transformer can only stay up for a few seconds. just when serious damage is around the corner that the smartups will save your gear from.

the transformer based unit cannot boost for long periods or do so repeatedly.
what they do not tell you is the rise/fall,transient and refresh times on that unit. it is in the white paper.

anyways, i do realise the price of what you were looking at and what i mentioned. what you are looking at is still more affordable and better than the so called audiophile products for this task.

i figured i'd tell the whole story on this so when people see this in the future the answer is here.

edit: i forgot to mention never "daisy chain" off a power quality device! never ever! that means you find another use for that isobar if you get a line conditioner or ups. these devices rely strongly on ground presence. daisy chaining off of that seriously compromises the ground seen by these devices.

So why hasn't my $50 belkin UPS turned my $5000 Headphone rig to airborne shrapnel yet? And why does it sound so much better then well over $5000 of "hi-end" power conditioners I've owned through the years?
My ears do not lie and they're telling me to sell off the best conditioner I found valued @ $600 for these uber cheapie UPS’s?

I'm not nearly as experienced on this subject as music_man but I'm wondering if you've experienced a loss of power yet requiring your UPS to become active supplying battery power to your gear.

Yes running staight off the battery's nasty dirty, I've unplugged a few times now. That what he's referring to? cuz i thought it was just an unbalance in feedback.

Tripp-Lite owned by Cisco..? Hmmm.... yummy
Everything Cisco makes, or is associated to is pure gold. I would be wrong not to try one of these. But my question still remains.

musicman,

How's this one http://www.tripplite.com/products/pr...productID=3151 for,

that one is line interactive. tripp offers "affordable" on line units. they are the only company that does.

my smartups all say "true sine wave output on battery" on the back plates.

as far as it not blowing up i am sure it did not. however, feeding a diet of square,notched wave current cycles to quality electronic items is not healthy.

like i said the idea was better power, right? simulated sinewave is worse than most ac you will find. if that $60 unit has avr, your gear that can benefit may indeed sound better. that is due to the avr coils not the batteries.

greatdane, i have run off battery. however i am running big quality units on amps. if the power takes a dump while the amps are playing i do not sit there and listen. i turn them off at once. it is a failsafe safety measure(on battery). not for long term power. a large amp that is "working" should last about 5 minutes on 1500va. at idle, which is what is important it will run them for a few hours. this is because i always keep my gear on and warm and may not be there to catch a horrible power sag/outage that just kills electronics(over time). that is what the batteries are really for in this application. the avr is what does the "conditioning" work.

the avr is what is really important on these. everyday your ac current fluctuates in tiny amounts millions of times. the online units that always stay on battery are different than the smartups you all are talking about. those must be sized accordingly. for a 500w into 4 ohms amp you will need a unit with a 20 amp supply. if you play loud figure 30 at 1 phase. 3 phase is easier.
that is not really realistic for a home though. these are much more important for digital gear. the analog stuff can live with less protection. that does not include op-amps. those should be protected also(aka, most headphone amplifiers).

Can I assume that the SU 750XL would be up to the job for my digital stuff (Squeezebox + Big Ben + Tact 2.0s + Dac1 + Central Station)? (http://www.tripplite.com/products/pr...productID=3299)

Ps Music Man,
What's up wrong with the CS power supply? It may be cheap looking but seems quite large. Heck it's half the size of my Benchmark which does the job just fine.

It's the F6C900UNV. She's AVR and basically a locked 120, haven't seen it move since i got it.

So this isn't going to damage my equipment right?
Hope not cuz she sounds absolutely astonishing!!


Here's my thread on it.

Stop by and give your technical opinion. Would be much appreciated.

the su750 will do the job.

the belkin is ok for using it as an avr.

the idea is not to run the line interactive units on battery for listening.

if the equipment is "working" and not idle, yeah it could cause damage.

i'd have to see the scope on one of those units to see how notchy it is.
it may be safe it may not be. it will not ever sound good on battery.

the su750 from tripp will.

i run a larger belkin on a computer system i can afford to loose. those little ones are really disposable. the battery costs 90% of the unit.

if i had good audio gear(which i think i do) i would have a better ups or none at all.

as far as finding them on ebay, in large cities you can go to auctions and get 5 units for $40. 4 will probably be completely dead. the 5th. will have a dead battery. hop on over to tiger direct and get a $50 battery. bring your van or pickup. then for $90 you just got a $400-$700 unit.

do realise that getting these used is not a hobby for electronic newbs. they can explode violently if there is a big problem with one. i plug all used ones into a isolated variac first to check that they will not kill me.

If you have a buzzing noise, that one would be defective, please stop using it, I have four of them and they are all dead quite, there is no reason why they should make any noise...unless defective...

no! i'd just assume recomend apc. the problem is that apc does not offer an "affordable" online unit. if you want to spend a ton of money be my guest.

if you mean because i did not recomend belkin. well, that is because belkin is generally trash. you know we all have our opinions around here but i bet a lot of people agree with me on that.

tripp happens to make solid products as does apc. that does not mean i "represent" either company. go ask patrick82 if he works for nordhost.

Does anyone happen to know which UPS units require active cooling?

We have TrippLite's SU1000XLA at home and it has an incredibly loud cooling fan that is on constantly, the UPS is locked in a room with computers but can still be heard, even over the not so quiet computers.

From the pictures it looks like the APC UPS below doesn't have a fan but I could use a confirmation from someone with the actual UPS..

http://www.antonline.com/p_APC--SUA7...TA-_178825.htm

edit: hmm, APC rates it at 51db at one meter from the case, their SUA1000 is rated at 41db

Anyone know if the 750xl's fan is as loud?

the apc consumer related units only use a fan when they are on battery or during a deep recharging cycle.

by consumer units i mean ones people might use on up to a 20 amp wall outlet. bigger ones than that have very active cooling. also online units tend to have active cooling. the giant ones that a crew of electricians install have antifreeze running through them.

Hmmm,
That's good to know. I have a fanless "quiet" computer and it sounds like the noise from the Tripp would sort of defeat the purpose. Used in the same room as my Hi Fi fan noise would be would be even more unacceptable (I was looking into the SU750 myself). Sure glad I'm keeping up on this thread. One always has to watch for the "catch" that hasn't been anticipated!

The fan noise issue is something I wasn't aware of too.

The choices have narrowed.

Thanks guys.

there used to be a company i think from canada or france. they made a super good online unit for like $300 or so. i do not remember the name and have no idea what to google to find it. you guys might want to check some power quality companies websites to see if you can find this other brand.

i have no idea if it used a fan.

the thing is that online units are always on battery. when batteries are charging there really needs to be an exhaust fan going. it is not just for cooling. when batteries are charging they put out explosive gas!
that is another consideration. if you are going to be switching on and off large loads around large batteries or smoking around them maybe a ups isn't for some of you either.

everything has some upside and downside.

tripps avr is still very good for a good price.
like i said before, avr is really the important thing on a non online unit. the audiophile avr's(power conditioners) look like they have lots of big fancy components inside. i do not consider that necessarily a good thing. that was mentioned here as well.
