1.3.5 Power Supply Module Operation
Power Supply Modules are offered to handle:
• AC or DC input power
• Base station/repeater requirements
A Power Supply Module is used in a base station/repeater with a Power Amplifier Module (e.g. rated
at 100 W output power).
• AC Input Power
The model generates the +5.1 V, +14.2 V, and +28.6 V operating voltages for the base station/
repeater modules.
These modules have power factor correction and include a connection for battery backup.
• DC Input Power
The model accepts a DC input (+21.7 to +32 VDC). The output voltages are:
- the input filtered voltage
- a regulated +5.1 VDC
- a regulated +14.2 VDC.
