Paul, My sense is that you are better of buying a used 50v supply from the telco equipment industry than you are trying to build one. I especially like the Valere rectifiers, like this one: http://ww

REPLY: Are you sure that's a complete power supply? The ad calls it a "rectifier module". Bill, W6WRT _______________________________________________ Amps mailing list Amps@contesting.com http://list
Eltek 'rectifiers' do appear to work well but they are designed for charging 48V (4 x 12V) battery banks at typically 53-57V and may not have the regulation you would expect. I am using Meanwell/Sunp

Thanks for the video Mike--I did end up with an HP in the lower end of that price range. I didn't really consider doing two boards but the kits from NL that PE1CKK used look nice. A couple dividers a
Paul, If you're building an SSPA for 6m or 2m then also consider the F1JRD designs using the MRFE6VP61K25H - its rated at lightly more power than the MRF6VP11KH and is more robust. See www.rfham.com
04/02/2013 19:41 Any neat way to get power in and out of those units Mike, if used as a bench top supply, rather than built into the amp itself? Can they be stacked to double the current? Cheers. --
These are modules designed to plug in to a rack mounted shelf which supplies connections to AC input and DC output. The completed unit charges a 48 volt battery system. 73 de Mike W9OJ My sense is th
You sure that is a complete PS? I read it as if it's just the rectifier module. 73 Roger (K8RI) They have been called... rectifiers for the last 60 years. Yes, they are 100% complete power supplies.
Hi Mike I like your SSPA ! How much attention did you pay to its "health and safety" ? The necessary foolproof control and monitoring circuits are putting me off at present. Regards John G4ZTR _____

Except for the control, voltage adjustment and metering. The later ones would be pretty difficult to try to run without a chassis and control. Unless you have a detailed schematic of both the rectifi
