Mantamuzza 0 Posted October 15, 2018 Gday I have contacted both Swann and some ups company but have not really found an answer. Basically I am looking for a ups to kick in for maybe ten minutes if power is cut. This is the system I got (yeah I know not great but all I could afford $179) https://www.swann.com/au/swdvk-444804bv This is the UPS I was thinking https://www.officeworks.com.au/shop/officeworks/p/cyberpower-650va-backup-utility-powerboard-ups-in3229148 Any thought or suggestions Cheers Share this post Link to post Share on other sites
Cortian2 3 Posted October 22, 2018 In general terms: Figure out how many watts your load consumes and size the UPS so that's about 20% of the load. That will usually get you about 20 minutes of run time. Try to choose a UPS that has an end-user-replaceable battery. They're only good for about 3 years. You should do a run-time calibration (for UPS' that have that option) or run it down to shutdown about once every 3-6 months, otherwise the plates in the battery will plate, reducing capacity, and you won't know when the battery needs replacing.
