WTB: 2 or 3 sepex controllers

I'm looking for 2 or three sepex controllers. They need to be capable of 48V or more so the smaller ones from pallet trucks are out.

I need two identical for parallel drives on my zero-turn conversion project and ideally a third for another conversion.

I'm in Quebec, Canada (near Montreal) and can pay shipping, especially for multiple controllers.

I'm possibly interested in other bits and pieces: contactors, 500A series controller, etc.
