PWR2 Power Card
The Power Card supplies the power for the other Cards in the receiver. It requires 16.5 VAC from a 115 or 230 VAC, 50/60 Hz, transformer. The Power Card is equipped with automatic battery charger and backup battery connections. In case of AC failure the Power Card automatically switches to backup battery power. The backup battery capacity can be between 7 and 15 Ah. The Power Card supervises the presence of the battery and the battery capacity and the current status is reported to the CPM Unit.
