The cheapest way is to obtain 2 computer-power supplies from the junk-yard (=3D for free). Then you have to open both, disconnect the negative supply from earth-potential (but of course NOT disconnecting the earth from chassis!!!) and connect the 12V supplies in series. This is simple and cheap! 73 OE3GHB Gerhard Am Dienstag, den 07.12.2010, 12:44 +0100 schrieb pa3abk: > I'm using a Conrad PSU 24VDC @ 10.5A EA-PS 524-11-T from EA - German=20 > technology made in China ;-) > Best.-Nr.: 510120 - 62 [Teilenummer: 35 320 133] >=20 > Didn't find any spurious yet of MF and HF although using open feeders. > There is also a sensor available to eliminate the voltage drop over the= =20 > cables. > It comes with mounting brackets. > A 48VDC version is available. > Just check Conrad.de for details. >=20 > It's also possible to use the cheaper "mousetrap" PSU's, but as QRM and= =20 > noise is not acceptable I choose for this one. > The few euro's more doesn't justify the irritation and trouble to=20 > eliminate the QRM. >=20 > Initally I had the TX with unstabilized PSU, because Class E final is=20 > calculated with a certain voltage and associated L/C result was rather= =20 > irratic. > This PSU gave me a stable PA 24VDC/5,6A in and over 100W out. > Jan/pa3abk >=20 >=20 > Op 7-12-2010 11:33, Horst St=C3=B6cker schreef: > > Hello, > > I am looking for a power supply 24V/10A.
