For sale is a Fanuc Power Module Board A20B-0003-0630 05A. One per bid, two available. This part comes from a functional Hitachi Seiki HMC with a Fanuc 3000 controller, that I bought to part out and scrap. I was told that it was working prior to the company going out of business. I am not set up to test those boards and it is sold AS IS without any guarantees.
