Members satannica Posted October 1, 2012 Author Members Share Posted October 1, 2012 We checked them out just to see since we play a lot of outdoor gigs with generators.The little Triplite work for spikes more than for conditions you get at bars or other things like generators where loads vary. When we tried them I set a variac on about 90v for a minute or two with a simple 100w light bulb as a load (the 1200VA its supposed to regulate). It maintained some until we added a second load (100w light bulb), then it shut down.I have two of them though. One for my wife's computer and my sons computer. I have the bigger rack mount 2400 series for my home studio and computers. I like it for the ability to quickly save my work before it shuts down. Given the load on that 2400 (2 computers and a few pieces of small rack gear) it provides about a minute and a half before it shuts down (during brown outs). There are other APS units with longer VA specs but a minute or so is enough time to safely save work and shut down.Those Furman Voltage regulators work to provide additional current boosting to the load during underages and will maintain that line up to the given load requirement. For the opposite condition the current will be dropped during over voltage line conditions.The AR1215 a max of 45A which is why we used them for lighting and PA. More than enough to regulate high demand gear with high power fluctuations like Pro Audio, lighting, and guitar amps etc. Of course if the venue only has a limited amount of power circuits, as we have seen in the past, the system will just do a soft shut down vs an abrupt cut off.Our rack power regulators were tested recently when a commercial refrig unit blew a line at one of the bars we played. {censored}ing lights everywhere were off, others flickering. The PA was working fine and then shut down right before the mains blew (a few seconds). I love your posts. Straight to the point, no bollocks and backed up with real experience!

The PA was working fine and then shut down right before the mains blew (a few seconds). OK, I just realized what you're referring to - you're referring to a battery backup. That Triplite unit that you replied about (and the APC Line-R I mentioned earlier) are nothing more than an automatic tap-switching transformers. There's no battery, just as there's no battery with a Furman unit. The top-end Furman rackmount unit is the same thing, with more taps to switch between. Result is that it's got a tighter range of output power, but, it also switches around a lot, which you will hear in your amp. I had one at my house and it did exactly that...and that's my house - not a bar that has coolers, air scrubbers, and AC kicking on and off... If you're looking for line regulation, the TrippLite unit would do the trick for a lot less. APC might have a Line-R that's for 220/240, I don't know - I have no need for that... Anyhoo Also, 45A? How the hell are you pulling that from a wall outlet? Wall outlets are rated 15A...as is the AR1215 - that's where the "15" comes from.http://www.furmansound.com/product.php?id=AR-1215#fragment-2 Regarding soft-off, if your amps have reserve power (ie, large caps) then they go down soft. Your board might not, which that can make for a thump... Trick is to power them off before the power comes back online. That way you don't slam your cones with inrush (the thump)...but a well designed amp will soft-on itself. Link to comment Share on other sites More sharing options...

It tells you what the voltage is, but does not contain a voltage regulating auto-transformer. Link to comment Share on other sites More sharing options...

Members Nerine Posted October 2, 2012 Members Share Posted October 2, 2012 Hmmm. This is relevant to my interests too. I'd be into getting some kind of power device that will help kill unwanted hums and clicks and pops and interference in some venues. Seems the jury is still out on what to actually buy.

Members Miter Gauge Posted October 2, 2012 Members Share Posted October 2, 2012 I wish I could remember the voltage regulators we used in the studio where I used to work. The were about 4 rack spaces and couldn't have weighed much less than 100lbs but they worked great. The building we were in was over 100 years old so the power was iffy at best. Edit: I think it was something like this: http://www.bhphotovideo.com/c/product/657355-REG/Furman_P_3600_ARG_P_3600_AR_G.html I had NO idea how expensive these things were. We had a bunch of them.
