The PAMU is used to monitor the BSC power distribution box.
The PAMU performs the following functions:
- Detects the voltage of six -48 V power inputs and generates alarms (only four inputs are used by the BSC)
- Detects the status of the power switches for 20 power outputs and reports alarms
- Enables the switchover when faults occur in the serial port communication, and communicates with the GSCU
- Provides two RS485 and two RS232 asynchronous serial ports
