Category: Power Supply February 15, 2018 Anderson Powerpole chassis mounts Dave WI6R showed off his aluminium chassis to the list, but this resulted in questions about how he mounted his Anderson 12v powerpole connectors. The purchaser needs to assemble the board into an enclosure and wire up sockets, encoder and potentiometer and provide a power supply in order to get the transceiver working. This relies on the fuse in your power supply to burn out if the power supply is connected the wrong way round. 8v supplies with the µBITx and the BITx40, and quite happily over a reasonable period of time. This assumes that the power supply is adequately fused (at a level suitable for the µBitx – around 3 Amps). The solution is simply to install a fuse (or better – two fuses, one for each of the power connections on the board).
