Howdy! Just purchased some new power supplies for some equipment here.
The first one I bought was something I've been after for as long as I can remember, this model is best described perhaps as a battery iliminator and can supply output voltages from 3-12 regulated. So what you say? Well firstly this power supply isn't the "run of the mill" type of terribly noisy wall plug pack you'd buy at your local Walmart, Woolworths or similar, we're talking about a bench top switch mode supply which delivers a 3 amp current output at any of the voltages listed above, at 3 inches square this supply is amazingly small given the amount of current it can handle. The supply comes with 2 screw terminals which have banana plugs at the end, the supplied accessaries include a lead with spade clips at one end for connection to the supply and a connector at the other to accomidate one of the supplied plugs which can be plugged into whatever gadget you wish to power, 7 of these plugs in all and I've found that I can power everything I have with this unit and the supplied plugs right down to my old and faithful Sony pocket MD recorder <smile>. The other supplied accessary is a spade clip to elligator clip lead, just the sort of thing you may need if you wish to test something or run a gadget that doesn't fit one of the supplied plugs. The supply also has overload protection. And to the second supply I bought which is just your standard regulated 13.8 volt DC output 2 amp supply for powering some CB radio equipment here. So now to the question, the first supply I mentioned was a switch mode type and the second supply uses the humble old transformer to supply the current and I ask why are transformers still being used in CB supplies? I thought the whole idea of a switch mode supply was to enable the use of high current efficiently and surely that quality would be a first feature in a supply to give power to radio equipment. ======================================= The Techno-Chat E-Mail forum is guaranteed malware, spyware, Trojan, virus and worm-free To modify your subscription options, please visit for forum's dedicated web pages located at http://mail.tft-bbs.co.uk/mailman/listinfo/techno-chat You can find an archive of all messages posted to the Techno-Chat group at either of the following websites: http://mail.tft-bbs.co.uk/pipermail/techno-chat/index.html Or: <http://www.mail-archive.com/[email protected]> you may also subscribe to this list via RSS.
