Hawthorne wrote:Would an UPS work for an M Series machine (passover humidity)? Some here have said it does. If so, how many hours, at a time, would a good one last?
I'm not very knowledgeable about this kind of thing so have to ask some other questions -
Would that kick in, uninterrupted, if the power went off in the night?
Would I keep it connected to the machine all the time?
Do UPS recharge themselves if they remain plugged into the machine and the wall of course?
Our power outages are USUALLY short lived (maybe a few hours at most and not very often).
What would be a good one for my purposes?
Thanks.
Hawthorne, the answers to your last 3 of 4 questions are YES.
For passover humidity mode, that is NO heating, you simply turn the humidity knob to 0. There has been reports of problems with UPS if you use any other setting of the humidity, the M-series humidifier does not like the power from a ups.
The power used by your M-series will depend on the pressure, and also the intended and unwanted leaks. Unfortunately most consumer UPS machines do not quite give the total output AmpHour capacity, they simply say how much max power. Many will give some indication of capacity as '1 hour with a small computer', in very general terms. They almost always overstate the capacity. Also the capacity decreases steadily with age, as much as 20% per year. Their use is best for short term outages, unless you buy a larger model. Somebody here who has actually used one of those machines, and has experienced how long it works with M-series, may post and give you the value for a particular model of UPS, and then you need to guess/adjust it to relate to your pressure.
Make sure you can get a UPS where the alarm can be turned off when the power goes off, otherwise that would wake you up, even if you have uninterrupted xPAP therapy
