This is the original equipment power supply for the Respironics "Legacy" or pre-M-Series BiPAP machines. This power supply will automatically adapt to both U.S. 110v current and international 230/240v current. It draws 60 watts and supplies the correct 24V of power to the machine. The part number listed on the bottom of the power supply is 1012832 but the reorder number is actually 1043065.
This power supply will not work for the newer Respironics "M-Series" machines. It is not designed for use with DC Battery systems - see the REMstar DC Power Cable for connecting your machine to a 12V cigarette power supply.
