A number of power supplies now feature Anderson Power Poles. Is that the connector you’re referring? Of course, Elecraft transceivers also use the Anderson Power Pole connectors as does Flex Radio System transceivers. West Mountain Radio offers the “Rig Runner” series of DC Power Splitters using Anderson Power Poles that feature varying number of connections as well as individual fused ports (they use Automobile fuses) where if the fuse blows the port lights up, with the device rated for 40A. I just saw an advertisement for a new product (4006U) that also includes two UBS power ports as well. See: http://www.westmountainradio.com/rigrunner.php There are also other manufacturers/distributors of DC Power Splitters, such as Powerwerx, and MFJ that offer their own variations of Anderson Power Pole DC Power Splitters. Installing Anderson Power poles is relatively easy if you use the proper crimper. All of my DC power cables use Anderson Power Poles because the DC Power Splitters make it easy to wire the station, it is easy to add/remove power connections, and provide a standard fitting that makes it easy to relocate equipment to another part of the station or somewhere else (e.g. I use them in my Volvo XC70 as all of my ham gear works off DC Power Splitters). Each connection can also be locked in place in the power splitter with an insert that comes with the power splitter (they’re provided with the WMR products; otherwise, you can buy them separately).
