I ended up ordering 4 of the ones I pictured earlier. I had to modify it with a 470 ohm resistor, 100uf capacitor and a NPN general purpose transistor. I also had to find the adjustment for voltage and drill a hole in the case to easily access it but that wasn't hard. Added the mods and the power comes on immediately. They are actually a little smaller than the Meanwell LRS series ps. But, not bad packing 750 watts at 62.5 amps.
