3 Phase DC Power Supply

Post by rallyx99 »

I was wondering if anybody has used (multiple) Centroid rectifiers to create a 3 phase DC power supply? I'm installing my AIODC on a machine that uses 40in/lb DC servos (180V) and I'd like to keep the load balanced across all three phases of my shop's power. I'm kind of hoping for a sub $500 solution here and have been investigating ways people have connected multiple single phase bridge rectifier setups to make a three phase supply. My shop has 208v (120v l to n) 3 phase power, BTW.

I appreciate your thoughts.

208V 3Ø to 120V 1Ø transformers are readily available. All you need is the Centroid "capboard".
Cheers,
