Still got boards and cables available. We're now shipping the V0.5 boards, which have a better supply-side socket (better more reliable fit) and improved current metering. We're working on PCB design for DPS-2000BB boards and should be prototyping soon. We're also working out a package kit for tying three Z750 supplies together with a single control board with better status LEDs and unified control, that'll allow you to load-balance them together into a single ~2200W unit.
