There is a drone which I’m experimenting with and want to move from batteries to a 2-15 meters 14AWG tethered cable.
The drone voltage is 15-21 Volts and consumes up to 200 Amps.
What would be the best method of searching for and the best brand, model and condition new or used, to find a good but not expensive power supply for the drone?
14 AWG is not going to be enough. Chances are the cable required for 200 amps is going to be too heavy for your drone to comfortably lift.
If you’re still looking for a power supply, Astron will likely have something that will work. You might have to parallel a few together though. You will need at least a 240 volt ac outlet to feed your power supply though.
Correction: Astec rather than Astron. (Although Astron might have what you’re after too.)
Are you currently (heh) pulling this off with batteries?
