Hi have a control box for sale. This has 3 RSP-320-36 supplies in it. I have not used it for a while but I am sure this is the one I used as my daily driver for my machine. Having these supplies in it means you can do merge moves on placement without worry of voltage dips. I think it is one of the reasons placement was actually quite accurate for me.
The supplies themselves cost £50+VAT new alone.
I am sure it is all working but it is sold as seen. I cant upload any images as it says site if full, contact Mike. If you want to message me your email address I can send images.
