Discontinued. For reference only. This replacement 60 watt power supply for the PR System One REMstar CPAP machines is compatible with all 60 series System One REMstar CPAP machine models which don't have the heated tube. The power supply is made up of the "brick" that connects directly to the back of the CPAP machine via a 4-foot cord, and it does not include the detachable C7 power cord which attaches to the wall outlet.
Here's a link to the System One Power Cord that attaches to a wall outlet. The C7 power cord is compatible with both the new REMstar M Series and System One REMstar CPAP machines and the discontinued REMstar CPAP machines.
If your 60 series REMstar (like 260, 460, 560, 660, or 760) has the heated tube option, then you need the 80 watt power supply.
