5.3.4.7 Power supply
The ADS 150X is the power supply module of the main cabinet and expansion cabinet of the Aastra
XS.
The mains power supply voltage has the following characteristics:
•
Rated voltage: 115V or 230V compatible with 110V/220V
•
Tolerances: +/- 10%
•
Frequency: 50 or 60Hz
•
Power: 100 W
An optional, external 48V backup battery can be installed (see Autonomy section).
The ADS 150X includes the following functional blocks:
•
A 48V converter providing the following voltages:
•
+5V / 5A
•
-5V / 0.1A
•
+12V / 0.15A. This value does not include the fan power supply current.
•
-12V / 0.55A,
•
-48V / 0.45A
•
70V / 0.06A ringer
•
A 48V rectifier supplying a 3A current, used as follows:
•
1.35A for the converter,
•
0.9A for the DECT telephone sets and base stations
•
0.75A to charge a 7.5Ah battery for 10 hours (battery will provide 4 hours autonomy to
the AXS).
The rectifier can be connected to 115V or 230V, 50Hz or 60Hz main,
•
A fan supplied with 12 V DC by the converter draws the air into the cabinet through the left-
hand side.
Furthermore, the ADS150X generates an alarm in case of failure of the rectifier or of the converter.
