Momentary power interrupter

[Mattlt]

This may be a solution without a problem, but here goes.

I am looking for a device that I can plug in to a 120V outlet that can produce a momentary (1-2 second) power failure, based on a timer.


Here's why. I use a CPAP machine for sleep apnea. When I turn it on, I also turn on the heated humidifier. During the night, I end up with a lot of condensation in the tubing. By morning, I usually wake up to water everywhere, or at least to the gurgling sound of a water-filled tube. If I could cause a momentary "power failure" say 3 hours into the night, it would shut off the humidifier (the machine will restart itself based on breathing, but will NOT turn on the humidifier automatically.)

Things get too dry if I don't use the humidifier at all. I haven't been able to find any info if the machine has different heat settings on the humidifier. Maybe that's an option too. I just thought this was one way around it.

Anyone ever run across such a device?

Look into the verious Intermatic 24 hour timers.

You can program them to come on and off when you want.

(I don't know if 1 or 2 seconds off is programable. But 10 or 15 min should be.)

Is the humidifier an integral part of the CPAP machine? If not, you could just plug it in with an Intermatic (or similar) timer, set to turn off halfway through the night. If it is integral with the CPAP I don't think the average plug in timer you'll find at the hardware store has the resolution to turn off and on within a few seconds - they have digital models that can probably turn on and off in a minute, if that's not too long a time period.

Does the humidifier have a water tank you have to fill up? If so, maybe you could just fill it halfway, or to whatever level required to make it run out halfway through the night.

Seriously doubt you will find a wall plug in device for less then a few hundred.

Company called IDEC makes cycling timers, the one I purchased off Ebay for a compressor drain will provide any number of cycles in a 24 hour period, for any duration, normal closed or normally open contacts, various voltages. Search Ebay for IDEC.

The humidifier is integrated. Good idea though. I've thought of the generic hardware store timer - this machine pretty much chokes me when the power goes out. A 1-2 second outage wouldn't be a problem, anything over that would probably wake me up. (hopefully it would wake me up!)

They also caution against running the water tank dry.

they told me to keep the machine lower then the bed to prevent that.
can not tell you if that worked or not, only used the machine a couple times. did not help me at all.

See if the humidifier has a delivery rate adjustment, maype an orifice or valve? Also the plug in wall timers can be used to provide a short off period but it may be too long for your application.

I do not use a CPAP machine but my humidifier is wired to a power strip so I can just reach over and turn it on and off as needed. It also has an adjustable output. I don't sleep soundly anyway so I wake up many times during the night.
