[MRCA] 24 volt power supply

[jeepp]

Mike,I bought some 7A and 16A units from EBAY. They did put out some rfi.  However, using a Corcom filter on the a.c. input and some .001, .01, and a 1000uf on the output, plus installing it in a small cabinet and bonding everything, no more real issues.  That is, on 80 and 40 meters.  Given the cost... works for me.Jeep K3HVG

Subject: [MRCA] 24 volt power supply 

I finally got my Harris RF-5000 transceiver working over the Christmas holiday. It only puts out 100milliwatts so the next step is to interface it to the Harris 125 watt amplifier.

The amp requires 26 volts at 12 amps so I'm looking for a 24 volt supply. Does anyone have any experience with the 24 volts switchers used with CCTV and LED lighting applications. Here is an example:

I'm concerned about the RFI it generates and the transient response with a varying load such as a SSB or CW transmission.

Any recommendations or suggestions are welcome.
