ResMed's S9 Series CPAP/BiLevel machines use an external power supply with AC Power Cord. There are two versions of the power supply: a 90W version which is supplied as standard with the system, and a 30w version available as an optional accessory. Both power supplies are designed for universal inputs of 100-200V, 50-60Hz and can be used in most countries around the world.
This S9 90W Power Supply measures approximately 6.5 x 2.5 x 1.5 inches and weighs approximately 1.25lbs. It is designed to power both the S9 CPAP/VPAP and an H5i Heated Humidifier. It can also be used to recharge ResMed Power Station II CPAP/BiLevel Batteries.
Usage Information: This 90W Power Supply includes an AC power cord for use in North America. A plug adapter may be required for use in countries outside of North America.
