Dear Group, I am considering a suitable power supply for the K3/100.
One manufacturer whose supplies are readily available on our Australian market and well documented is XP Power. These supplies are manufactured in China but judging by their datasheets, they seem much better quality than those from our retail stores. Only other alternatives such as Powerbox are twice the price or I could import an Astron switcher (their linear supplies are 110VAC only). An XP Power model I’m considering is the LCL300PS12, from their LCL series; datasheet is shown at http://www.xppower.com/pdfs/LF_LCL.pdf . They sell for about $180 ea. I have some questions for readers and Elecraft please - 1. The LCL300PS12 can provide 25A and has an adjustable output range of 11.0 to 13.0V. Is this suitable for the K3/100? XP Power’s 12.5 to 14.5V model isn’t available here. 2. Pages 8 onwards of the data sheet show spectrum plots of the supply’s conducted emissions. I don’t have a feel for dBuV, so are the levels shown a concern? I can’t see any plots for radiated emissions. 3. Has anyone used these supplies and been happy with their emissions and level of audiable noise? 4. Should I consider something else? Found this which looks expensive: http://www.barrettcommunications.com.au/2022.html Also have noticed a lack of mention in Elecraft’s forum of TenTec’s model 941.
