The following sections describe the operation and interaction of the different subsystems.

9.1 Main components

9.1.1 Power management subsystem
AC/DC Power Supply Unit
The AC/DC power supply unit is a compact, medical, switched-mode power supply with a
universal AC input. The high-efficiency design minimizes heat dissipation.
The AC input may vary between 90-264 Vac, 47-63 Hz single phase. It is designed to output
15.7 Vdc ± 2% and 110 W continuous output power for the DC/DC board.
The AC/DC power supply unit has over-temperature, overload and overvoltage protections.
Input protection is implemented with the fuses in the AC inlet.
Battery
The patient monitor has one optional, rechargeable 11.1 V, 6210 mAh lithium-ion battery,
located in the battery compartment.
The battery cable connects the battery board to the DC/DC board. The battery pack supports
Smart Battery Data and it communicates with the DC/DC board using the System Management
Bus (SM Bus). Battery management is handled by the DC/DC board.
