Hi Paul I use 2 70 amp Astron's the one running my K3's and KX3 is a VS model set to 14.4 volts. It is attached to a Low Loss PWR Gate which charges 2 Optima batteries using the power supply. If a power outage occurs it automatically switches to battery power you never know when it happens.
The battery is fused then the PWR Gate runs to the Rig Runner where the radios are powered. The fuses that you have should be good for one thing you never transmit on 2 radios at the same time anyway. Well most don't unless you're 73, Fred/N0AZZ K3 Ser #'s 6730/5299--KX3 # 2573--K2/100--KAT100 P3/SVGA--KPA500--KAT500--W2 running digital modes on one radio and another for CW/SSB. -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of PGrig Sent: Thursday, June 13, 2013 7:46 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Need a Fuse on the K3's Power Line? I was just looking at my new K3's (#7489) power cable, and see that it is not protected by a fuse (although I think I saw an instruction to use an in-line fuse if I connect it to battery power). I see what looks like a 20a fuse (or breaker) on the back of my K3/100, although I believe I read that it draws 25a continuous duty. I was thinking of connecting my radio either directly to a 70a Astron p.s. (which will also handle my 50w 2m mobile rig and a variety of other smaller loads) or through a 25a fused receptacle on a RigRunner, itself connected to the Astron. To fuse or not to fuse--that is the question, and what is peoples' experience with the RigRunner? -Paul Grigorieff, N1HEL ______________________________________________________________ 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 ----- No virus found in this message.
