robritchie Posted December 5, 2009 Share Posted December 5, 2009 Does anyone know of any good 1u or 2u UPS's for use with digital console and stage rack? Link to comment Share on other sites More sharing options...
DJ-Dulux Posted December 5, 2009 Share Posted December 5, 2009 We use APC for our home cinema DVD servers, never had any issues with them. Dupe... Link to comment Share on other sites More sharing options...
Jivemaster Posted December 5, 2009 Share Posted December 5, 2009 APC again! Also look on ebay there are always lots there. In all cases check battery life on standby (years) and hold up time under the load you need. Get a bigger one if the times are not enough for your needs. You may need to cancel all the bleeps associated with the various functions. Link to comment Share on other sites More sharing options...
TimmyP1955 Posted December 6, 2009 Share Posted December 6, 2009 Never used ACP rack stuff, but we (day job) gave up on the "regular" stuff - they just don't last. We use these: http://www.toshiba.com/ind/product_display...1=14&id2=22 The only down sides are: ExpensiveRack units have very deep chassisHeavy!Batteries are not field replaceable - they have to go back to Toshiba.No voltage selection - are 120V I/O only or 230V I/O only. Upsides are: Much more reliable than APCAre "On Line" type - no switching transients or delayClean sine wave outputStable output frequency - selectable 60Hz or 50Hz (suitable for use on Hammonds!)

Jivemaster Posted December 6, 2009 Share Posted December 6, 2009 Expect a rackmount UPS to need front and back fastenings. Link to comment Share on other sites More sharing options...
bruce Posted December 6, 2009 Share Posted December 6, 2009 If you're buying a second hand one, be prepared to replace the batteries - they have a lifetime of around 4-5 years. You might get lucky and find a good one, but then again you might not. Most units will be designed for an IT environment where they are powered-on 24x7, and rarely discharged. If you're using it in a touring environment where they're not connected 24x7, the performance may bear little resemblance to the published spec. And as someone said above - remember they're very heavy. They'll need to go in the bottom of racks, and be supported front and back. Link to comment Share on other sites More sharing options...
Jivemaster Posted December 6, 2009 Share Posted December 6, 2009 Also remember that the batteries used in UPS tend to have a life in the order of single figures of hard cycles! A full discharge to flat will eat up in the order of a quarter of the battery performance life. In a touring rack situation leaving the UPS ON as it is trucked from job to job will kill the batteries and they might take 24hours to recharge as far as they will.

mackerr Posted December 6, 2009 Share Posted December 6, 2009 What is there to save if all the show goes down, that cannot be saved to disc while programming Here's a start. The comm system so you can talk to each other as you try to fix the problem. The reboot time of all the digital gear that won't have to reboot if it's on a UPS. The amps power right up, the digital console not so much. Any eq, fx, or dynamics changes you have made as a regular part of running a show since your last save. Any speakers that might not like the huge bang when the console powers off before the PS capacitors in the amps have drained. The nerves of the operator.
