I have a 30A/28v variable power supply. It cost all of $400. My entire panel only draws 11 amps. I still don’t see why you need 50 amps.

To have a consistent 24-28 vdc output for a useful length of time, as I suspect would be required for a bench test setup, you would need a power supply with close to 40 or 50 A output to maintain the batteries state of charge.  If that is the case, why bother with the batteries.  Check on E-Bay

I use dual Odyssey 1600 batteries in series charged with a 24v BatteryMinder.

Hello LML gang,

 

Could I get some advice on the best way to get a 28 VDC 50 Amp power supply set up in our hangar?  On the web I’ve seen $5000 ground power units that can be plugged into our hangar’s AC power outlets to solve the problem…  Surely there’s a cheaper way to do this.  Anyone know of a more affordable source?  Maybe a couple of 12V car batteries ganged together with a battery charger in there somewhere. 

 

Suggestions?

 

Thanks,

 

Valin Thorn
