[/quote] The pure sine wave should be obvious. A simulated sine wave is done be a step approximation. They might divide the cycle into 8 or 10 or 12 or 16 segments; then use a step function to approximate a sine wave. The steps are discontinuities in the pure sine wave and each step contains harmonic frequencies. (Fourier transform and theorem.) Then the CPAP's switching supply contains inductors; and they don't like discontinuities. INFORMATION ON APNEA BOARD FORUMS OR ON APNEABOARD.COM SHOULD NOT BE CONSIDERED AS MEDICAL ADVICE.

For those that don't know, here's the Wiki info on it. Quote:The sine wave or sinusoid is a mathematical curve that describes a smooth repetitive oscillation.

Being rated at 600 Watts and my CPAP at 60 Watts, it "should" theoretically have a Runtime of around (10) hours correct ?

It stays in the SUV under the back floor panel, and I run an extension cord to the tent. Don't really care if it's not exceptionally efficient, since I actually have two of the batteries. It's more than enough for a long weekend of camping or an extended power failure. With a couple of fans and a light. And a laptop. If I were backpacking, I'd probably pick up a 12V Lithium Polymer battery pack. 12V @ 20 Ah is about 4 pounds and should run the machine with no humidifier for a couple of nights. However I'm bringing a 5000Lb vehicle, so an extra 150Lbs isn't a big deal. 8-)          MAPnea Posts: 183 Threads: 13 Joined: May 2013 Machine: ResMed S9 AutoSet - currently "set" on CPAP mode Mask Type: Other Mask Make & Model: ResMed AirFit F10 and P10 - varies Humidifier: ResMed H5i CPAP Pressure: 8 CPAP Software: SleepyHead Other Comments: New Sleep Doc + New DME = Trying new approach to PAP therapy.

Hi, JohnNJ, Do you recall how much this cost? Thanks! One of the DME's on the list had it listed for $699 and there's an adapter that's needed for the S9 for another$49. My insurance covered it all so I didn't pay anything for it. UPDATE: That DME (#1 on the list) now bundles the adapter with the battery, both for \$674.95. justMongo Posts: 4,412 Threads: 121 Joined: Sep 2013 Machine: ResMed VPAP Auto (S9) Mask Type: Full face mask Mask Make & Model: ResMed Mirage Quattro Humidifier: ResMed H5i CPAP Pressure: 18 IPAPmax - 11 EPAPmin, PS=5 CPAP Software: Other Software Other Comments: μολὼν λαβέ Sex: Male Location: Калифорния 08-28-2014, 08:54 AM (08-27-2014, 08:41 PM)Labrat0116 Wrote: So the UPS (below) should be good then correct ? Being rated at 600 Watts and my CPAP at 60 Watts, it "should" theoretically have a Runtime of around (10) hours correct ? Your comparing rates. You have to compare energy which can be expressed in Watt-hours (which are like Joules; 1 Joule = 1 Watt-second.) Here's a rough example. Suppose the conversion from battery to 120 VAC is 100% efficient and that the conversion in the power brick from 120 VAC to 24 Volts is also 100% efficient. Suppose the battery is a 12 Volt, 25 Amp-hour capacity. Pulling 5 Amps from will use energy at a rate of 5 x 12 = 60 Watts. But, 25 Amp-hour/5 Amp = 5 hours maximum before the battery is drained (and they never discharge to full Amp-hour capacity.) The system might be fully capable of producing 600 Watts -- but the battery would be drained in 1/10 the time = 0.5 hours. Also, in the above 5 hour example, neither converter is 100% efficient; nor is the Amp-Hour capacity of the battery in the UPS likely to have a capacity of 25 Amp-hour. These pure sine computer type backup will get you through short term black outs and condition the power in areas where regulation is poor. You might get one night with no humidifier. That's why most folks are looking a car battery size batteries -- capable of deep cycle such as Marine use. The most efficient way from that battery to the xPAP is to buy the converter made for running the the machine off a 12 Volt battery Lead acid gel cells, AGM, and the Optima AGM Spiral cell battery do not outgas when used with a proper charger. Nor do they spill -- you can mount them upside down if need be.

The idea of "Uninterrupted" power during a blackout is very appealing. Having to unplug and replug would only interrupt one's sleep even more than necessary. What's the better option when going to a stand alone car/marine battery for connection. Inverter or Direct connection ? Also, I worry about having to recharge a large battery in a bedroom setting. ie SAFETY factor. Is a trickle type charger sufficient in this application ? « Next Oldest | Next Newest »
