[ARC5] Good 24V supplies available

[WA5CAB at cs.com]

Roy,

PP-4763 and 4763A are rated 20-27VDC/60A continuous.

PP-1104(*) are rated 11.5-17.5VDC/100A and 23-35VDC/50A.  

PP-1104 is roughly the physical size of a BC-191.  PP-4763 has about the same 
footprint but half as tall.  I use a couple of the PP-1104's here as I work 
on both 14 and 28 volt equipment.  But if you only need 28 VDC the PP-4763 
might be preferable.  PP-1104, according to the TM, weighs 210 pounds.  PP-4763 
125 pounds.
