Re: [WISPA] Adding External Batteries to a UPS
Sure, though I'm guessing you might need to reverse the inputs since it probably defaults to the utility side. If your UPS tends to fail in a way that leaves the surge protection only plugs hot On Sat, Oct 8, 2011 at 12:42 AM, Scott Lambert lamb...@lambertfam.orgwrote: On Fri, Oct 07, 2011 at 07:46:13PM -0400, Dorn Hetzel wrote: The failing ups problem might be protected against with a dpdt relay with a 120vac coil, wired to select power from the ups whenever the ups output is energizing the coil and to spring back to utility power when the coil is off.

[WISPA] Adding External Batteries to a UPS
Looking at this UPS. http://www.tripplite.com/en/products/model.cfm?txtModelID=3007 It is small enough to fit in our standard outdoor enclosures. It also supports being monitored by SNMP. Problem is it does not have an external battery connector. Has anyone had any luck adding external batteries to a UPS like this? WISPA Wants You!

Re: [WISPA] Adding External Batteries to a UPS
We used these a lot in commercial building closets, because of their compact foot print, and excellent Power protection.. (Although never used the snmp card) We've pulled almost all of them out to date. The reason we stopped using them is that like all other consumer UPSes, they tend to fail bad, when batteries die, and not restore power to the equipment until a site visit to remove UPS from service. (although we did like that it has a physical on/off switch, not just button, to force UPS on state). Whats also a pain is that the internal batteries are NOT easilly removable. You have to take it apart in half, and hope not to short anything in the process, and prey the leads stay on when put back togeather.

The failing ups problem might be protected against with a dpdt relay with a 120vac coil, wired to select power from the ups whenever the ups output is energizing the coil and to spring back to utility power when the coil is off.

Re: [WISPA] Adding External Batteries to a UPS
Try the SMART1000LCD, 1000VA / 500 watts, from Costco, $89.00. Pull the battery, buy two more just like it from Interstate Battery, make 2 lines apx. 20 inches each with 1 male and 3 female. plug in male to ups threaded thru vents, put the three batteries on top the case and plug in. For ease of handling duct tape the batteries together horizontally. They will always come back when power is applied(default is ON), until circuit failure, about 4-5 years. Less if you have really bad power, like on a old dairy, maybe 3 years. -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Tom DeReggi Sent: Friday, October 07, 2011 3:17 PM To: WISPA General List Subject: Re: [WISPA] Adding External Batteries to a UPS We used these a lot in commercial building closets, because of their compact foot print, and excellent Power protection..
