I have several of the Roband Varex PSU's that allow stacking to gain higher voltage, but also that the current limit will work over the stacked supplies.

Wanting to use them to power valves during testing the current limit seemed a good idea, so I tried it and it did work. The lowest limit of the supplies set the total limit.

Whilst not of obvious use, possibly the service manual might reveal how this magic is done.
