I have fused my Elecraft radio equipment with inline power pole positive and negative ATC car standard blade fuses. I am now doing an audit of the fuses in my system to make sure they are appropriate for the equipment they protect. I realize there are internal fuses in many cases, I prefer doubling my protection with inline external fuses as well.
I have not read or heard anyone discuss the appropriate amperage ratings of fuses for my equipment or equipment in general. I would appreciate your recommendations on fuse sizes for these, as well as general approaches. Equipment and Specifications from Elecraft Manuals: 1. Elecraft K3s with 100 watt amp: Specs are 17-22 amps typical on transmit, recommended 25 amp power supply. 2. Elecraft KPA 500: Specs are PA Current 20 amp maximum. 3. Elecraft KX3: Specs are 1-2 amp typical current in transmit. One other important question. I have conquered much of the RFI in my radio room using power poles with extended thick Red and Black wiring wound around toroids. In this case the leads go from the Astron RS-35A to the K3s. I want to make sure there isn't too much drop in voltage over the extended toroid wiring. How can I best gauge what the K3s receives in this setup? The manual says it should receive 13.8 volts nominal, 11 volts minimum and 15 volts maximum. I think I am beyond the provided and recommended 5' power cable. I have not had any problems (that I know of). I do not have a desk full of electronic devices for evaluating this, so is there a simple way to be reasonably sure? 73 and thanks for your help, W7RPK, Peder ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
