Hi, We hunted around for quite some time and didn’t find much that we liked when we were using them, they all seemed a bit twitchy, but we’ve had good results from the APC ATS range - we have 10 or so of them in use. YMMV but they seem really solid, and we’ve have had no issues with them. We have the AP7721 (http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP7...) & AP7723 (http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=AP7...) - not sure they go as small as you’re saying you want to go, but there are a few options here: http://www.apc.com/products/family/index.cfm?id=14 http://www.apc.com/products/family/index.cfm?id=14. TechPac has them in stock from time to time. We ordered them through Dominic at Sereno. Cheers, Gerard On 18/02/2015, at 4:11 pm, Mark Foster wrote:

Hiya folks,

Looking for a cost-effective solution to automatically switch a non-redundantly-powered device between redundant power supplies. For example running a single switch between a UPS-backed power supply and a direct-mains power supply, so that I have some tolerance should the mains supply to the UPS fail (or the UPS itself).

Essentially something like this:

But i'm looking for something relatively small and for a relatively low number of devices (say anywhere from 1 to 3). I'm also not necessarily looking for >10A 240V; the gear that'll be being run, is quite low current.

Anyone got any recommendations?

Thanks Mark. _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog
