Re: Banebots RS-775 Case Short

We both agree that that wiring link is resistive and that the voltage it develops does eat in to the 24V supply's margin. We disagree on how much voltage is developed, how much margin the supply has, and how quickly the PTC blows.

The current necessary to cut out the entire margin budget is orders of magnitude beyond the points the protection devices cut in.

The PD schematic and design package are available for review on usfirst.org . If anyone is interested, please run the math.
