I have 3 of them in a load sharing circuit. Under modest loads, everything it OK, but when I increase the load to ~3.5 - 4 A, there is a slight (~3%) drop in output voltage. That seems a little high for a feedback regulated supply. Sharing of load is not perfectly equal, but seems reasonably close based on the Imon outputs. I didn't see any load regulation information in the data sheet (did I miss something?). Output voltage "should be" 29.5V (and it's right on the money with light load) but drops to ~28.5V with the load.
I noticed the feedback voltage is slightly lower with the load (about 1.18-1.19 V with load, 1.22 without). These voltages could be a little off due to the ground point I'm suing may have a slight voltage drop relative to the ground plane of the modules because of the high currents in the circuit board.
