Hello Everyone,
I have been reading this forum for the past few months while gathering parts to construct a Mechmate. There is certainly a wealth of knowledge here. I have just started the "kitchen table" project, and I think I've already run into a problem with my power supply. It is an Antec PS-6N63R5R12 which should give me 63 VDC unregulated to drive the motors, as well as 5 VDC and 12 VDC for the PMDX and any accessories. When I plug it in, I measure 65 VDC (close enough) and nothing on the other two outputs. I then diconnected the wires from the toroid (a pair of brown goes to one regulator and a pair of orange goes to the other). I am a ME not a EE, but if I understand power supplies well enough, I should measure continuity on the orange pair and on the brown pair (they are just loops of wire within the toroid, right?). Instead, I measure continuity between one orange and one brown, and the other orange and other brown. I thought I could just switch some wire inputs to the regulators, but when I plug it in again and measure A/C voltage that would be going into the regulators, both brown/orange pair combinations measure 12VAC. Not wanting to blow anything up already, I haven't reconnected any wires. But if I were to reconnect the brown/orange pairs to the regulator inputs, wouldn't the DC output be somewhere around 8.5 VDC? I hope you can follow this. Thanks.
If I am understanding this correctly, I assume the wires within the toroid are perhaps all the same color, then the color coded wires are splice on later.
