Power Supply - Hoffrichter CPAP User Manual

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 DC vehicle cable (optional)
3 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.
DC vehicle cable
For mobile use of the point 2, e.g., in a truck or a caravan, it is possible to oper-
ate it with a 24 V direct current (DC). For this you will need the optionally avail-
able DC vehicle cable.
Only use the optional DC vehicle cable to connect the device to a DC
power supply.
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 operating 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).
Before using the battery pack, ensure that you have read the powerpackpoint 2
user's manual.
