    He's close enough to me.

    But I can't be BOTHERED to even cast an eyeball on the schematics of an obsolete AND LOW GRADE contactor-reversing "1Q" 3-Phase-only DC Drive run off an RPC when I can...

    More than $1,200 if you use some NEW parts, surely. But don't pay new price for dice-roll used!

    EPrey rip-offs - Rad-thieving-well high on the list - can often be priced at more than new. Check...

    For a time.. it had been tought that an RPC COULD NOT work with a simple SCR-class 3-Phase-input-only DC drive.

    That barrier fell BUT.. the target machine had a 3-Phase-input DC Drive rated at...

    Wha'dideyesay? As far as we KNOW.. it was never an OEM machine-tool colour.

    And yet? It just LOOKS as if it would have been and "period correct" at that for the Older of Old Iron goods!

    Speciality goods, of course, exist. The problem is that absent equipment to work WITH them you are aready into "diminishing returns."
