Hey guys,
What's everybody using to provide 24vdc for your military radios? Two 12vdc supplies in series?  Home brew?  Do they make a 24vdc switching supply that will handle 10 amps or so?
Thanks for your input,

Anything with a dynamotor needs about five times the motor nameplate current for the starting surge...

I got a 2 KVA three-phase 115V 400 Hz rotary converter at a flea market but nothing I had was big enough to start it (rated at 27.5VDC at 115 amps!)

So I bought a 20 VAC, 5 KVA toroid transformer on ebay, a BFBR (big bridge rectifier), heat sink, a 220,000 uF cap, meters and shunts, and brewed up a 24-28V 120 amp brute force supply with 240 VAC input. THAT starts the converter all right. It doesn't even blink at smaller dynamotors :)
