How Vintage???
From Hurco KMB-1's, and obsolete even for THEM, as they are generally swapped out in any still-existing kmb1s.
But goddamm, are these, like, the FIRST solid-state 3 ph converters?? I have 3 boards from 3 machines, each weighs 45 lbs!!! Half of that is transformer. Parametrics is the mfr, it seems.
These are the boards that have those very large caps, in my DC cap post.
Basically, there's two screw inputs for the single phase, and a three-screw output for the 3 ph, rated, I think, 5 hp, by Parametrics. And apparently a variable voltage, so they were proly the spindle drive boards.
There is a terminal strip with a bunch cut wires. Will these wires/their components be necessary to operate this board, or can I expect to full 3 ph power (230 V) when I connect the single phase?
I'll try this later, just curious what to expect..
