This external power supply is for use with all PR System One 50 SERIES CPAP/BiPAP machines. This universal power supply is rated from 100-240 V, 50-60 Hz and can be used without a voltage converter in most countries worldwide.

Usage Information: The power cord/cable, which plugs into the wall, is not included. If you are missing that cord please see Cord Part 1005894 elsewhere on this site.

Compatibility Information: This power supply is only compatible with 50 SERIES System One CPAP/BiPAP machines. It will not work with newer 60 SERIES System One CPAP/BiPAP machines.

Is My Machine Compatible? System One 50 & 60 Series Differences
  • BRANDING = 60 SERIES System One machines include the words "System One" in raised embossed lettering stamped on both the machine and (if included) the humidifier. 50 SERIES System One machines feature branding that is painted onto the unit and the words "System One" only appear on the humidifier.
  • COLOR = 60 SERIES System One machines feature charcoal gray panels and metallic silver side panels. 50 SERIES System One machines are dark gray with ivory colored side panels
  • MODEL NUMBERS = 60 SERIES System One machines include reference numbers on the base of the machine that end in 60. For instance 560P appears on the bottom of all 60 Series REMstar Auto machines. 50 SERIES System One machines include reference numbers on the base of the machine that end in 50. Therefore 550P, 450P, 150P, etc would all indicate 50 Series machines.
  • HUMIDIFIER CONNECTIONS = 60 SERIES System One machines feature a 6-pin connection between the CPAP/BiPAP and the humidifier. 50 SERIES System One machines feature a 4-pin connection.

My P250 RemStar CPAP's power supply was intermittently going on/off and I was losing air during the night. This new power supply provided a firm connection between the P250 and the power source and therefore, provided a reliable air during my sleep. The new unit does not come with the cord between the AC Pow Sup and the wall outlet, which is great because I can use my original unit's cord.

  • Perfect Timing

  • I was out of town without the power cord to my CPAP machine and it was an absolute nightmare. No one was getting any sleep. I got this cord overnighted to the house and it was perfect. Arrived the next day, perfectly what I needed.

  • Just what I needed

  • The cord on my old power supply gave out and I ordered this one from cpapXchange. I was able to use the power cord I had so didn't need to order that part. It arrived quickly and the new one is not a cheap knock-off, it's the real deal and works great!
