Re: More info about mUPS

Thanks for replying mkx. Actually, I have another question related to the brochure: it says 1A out on PoE. It says nothing about charging the battery. Does it draw the power for charging the battery from that 1A too or if I hook a 24V 2A PSU up to it, I get 700 mA on the PoE and 1A and change on the battery?Brochure says max battery charging current is 1A ... so it'll take ages to charge that "massive" 18Ah battery when fully discharged even if power adapter used is powerful enough.
Other than that, 18Ah battery should be fine.
My thinking is if it goes down to about 30% and I usually draw the line at 50%, I'd be looking at 12-14 hours recharge times which I can live with.
My main concern with the 18Ah battery is that if it's not well regulated it can draw too high a current during initial charging and melt something inside the mUPS after only 20 cycles or so.
