The ABB 3ADT218587S0143 is a DCS880-S01-2000-06 DC converter — a 2-quadrant, 2000 A, 600 VAC unit in a H6 frame size. It converts fixed-frequency AC line power (50 Hz) to controlled DC for motor armature or field supplies in heavy industrial drives. The H6 frame means it needs a dedicated cabinet cutout and forced-air cooling; this isn't a panel you squeeze into a corner.
The 2000 A continuous rating at 600 VAC input means this converter handles a substantial DC motor load — think a large extruder, a mine hoist, or a mill stand. It's a 2-quadrant design, so it delivers power in one direction only; regenerative braking needs an external resistor or a 4Q sibling. The H6 frame size dictates the mounting footprint and thermal dissipation path — verify your cabinet's cooling capacity supports the heat load before committing the BOM line. Three analog inputs and two analog outputs are on board for speed reference, current feedback, or process signal interfacing. That's enough for a standard speed/current dual-loop control without an external I/O module. The 73 dB(A) sound level is noticeable — at full load the fan noise will be audible in an adjacent control room; plan for enclosure or remote mounting if noise is a constraint. Auxiliary terminals are rated IP00 per IEC 60529, IEC 60947-1, and EN 60529. The main converter body has a higher protection degree (check the nameplate for the full unit rating), but the auxiliary wiring points are interior-only.
