28 Description of Device
Power supply
The point 2‘s power can be supplied from one of three sources:
1. External switched-mode power supply (included in scope of delivery)
2. powerpackpoint 2 battery pack (optional)
External switched-mode power supply
For mains operation the point 2 has an external switching power supply with a wide
input range of 100 - 240 V alternating current (AC), 50 - 60 Hz. Thus it is possible to
connect it to an energy supply anywhere in the world.
Battery pack
To use point 2 while travelling and when mains current fails, the device can
be operated with the optionally available powerpackpoint 2 battery pack.
With the battery pack, point 2 CPAP and point 2 Auto CPAP can be used at least 8 hours
(at 10 hPa, 12 bpm, 500 ml tidal volume). With the point 2 BILEVEL ST20/25 an ope-
rating time at least 7 hours is possible (at IPAP = 12 hPa, EPAP = 6 hPa, 12 bpm, 300 ml
tidal volume, I:E = 40% : 60%, T mode).
Please note: Before using the battery pack, ensure that you have read the power-
packpoint 2 user‘s manual.
