Date 1.00 2011-12-08 ® TETRAFLEX V7.5 MANUAL - Power Supply for BS41x 4.6 POWER SUPPLY FOR BS41X 4.6.1 Introduction The BS41x Base Stations are provided with a flexible Power Supply scheme allowing it to run in a variety of different configurations. It can run from either mains AC directly, run from a DC battery source or a combination hereof with battery charging.
Doc. No. Damm Cellular Systems A/S, Denmark Rev. Date 1.00 2011-12-08 ® TETRAFLEX V7.5 MANUAL - Power Supply for BS41x The actual produced output voltage depends of the configuration. When battery charging is active, the delivered output voltage will vary around 54V, controlled of the micro-controller. The accurate value is determined of the charging voltage setting, consisting of a fixed voltage part and an associated temperature compensation setting.

Date 1.00 2011-12-08 ® TETRAFLEX V7.5 MANUAL - Power Supply for BS41x The PS411 is provided with a micro-controller to allow close monitoring of the actual operating condition of the Power Supply. In addition the micro-controller also controls the battery charging voltage. The PS411 is connected to HDLC-bus in the Base States as well as the serial UART interface. O&M communication is possible on both interfaces.
