"Will 15A house line supply enough juice for the K3S, KPA500, KAT500, and in the future a P3 Panadaper?"
When I added my KPA500 to my TS-590S station I found the drop in mains voltage unacceptable. I made some changes in power distribution and now have a web power switch connected directly to the 120 V outlet. That web power switch feeds the KPA500 directly and feeds the other station equipment via breakout strips. One port of the web switch has a permanently installed "kill-a-watt" monitor. The outlet I'm plugged into is just the other side of the house wall from the breaker panel. With this power distribution arrangement I run my KPA500 at 500 W output and PA voltage does not usually drop below 60 V. In a spot check on 20 m (the band at which my KPA500 efficiency seems to be worst) I saw 119.0 V with KPA500 standby and 113.4 V with key down 500 W RF output. The situation is a bit worse when the heat pump is running but doesn't seem to cause any operational problems. If I ever build a real station I'll include 240 V outlets. 73, Andy k3wyc ______________________________________________________________ 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
