Power System (12 volt)

I am a big fan of Anderson Powerpole connectors. Everything in my shack 12 volts runs on this type of connector. If a piece of equipment comes with a wall wart transformer I cut the cord off and throw away the transformer and fit the cord with power poles.

One of the biggest mistakes I see is hams adding a ring terminal to their equipment leads and connecting it to the back of their power supply.  This would be all well and good as long as the lead has an inline fuse with proper sized fuse.

The installations I have looked at rarely are done properly and have no fuse protection.  The Rigrunner has automotive blade style fuses that you can size accordingly for each piece of equipment you attach.  Not to mention in my case attaching 15 leads with ring terminals to the back of my power supply would  be one heck of a mess.

I have two power supplies. Ten-Tec model  9420 which is a 100 amp supply that runs my Ten-Tec Hercules II amplifier as well as an Astron  RS-50M to run everything else (except the 7800).

Its hard to beat the Astron transformer supplies and I avoid the switcher type models because they are often electrically noisy by nature. I just retired an Astron 35m that I have owned for 30 years. As a matter of fact is spent over 20 years turned on and plugged in. With the exception of a failed on/off switch.

From the Astron my power runs to a West Mountain Radio PWRcheck. This is an inline device that monitors power and connects via USB to your PC. From their my large feed cable runs down to a 12 port Rigrunner which also feeds a 6 port Rigrunner on every shelf.
