Got the tranformer, now I need to hook it up and I want to make sure i'm doing this right. Data sheet for transformer is here:
I'm assuming I'll want to hook up the greens to AC1 and AC2, with the blues to PGND. Also, the transformer has two sets of primary windings, red black. Hooking up one set to mains power delivers 22v across both sets of secondary blue greens, what is the point of the other set of primaries? Should I attach these too or is there no point?
