The ABB 3ADT218567S0242 is a DCS880-S02-4000-05R DC converter — a four-quadrant regenerative unit rated for 525 VAC input and 4000 A output. It sits in the H8 frame size, which dictates the cabinet cutout, busbar layout, and cooling ductwork for the installation. This is a 4Q converter, meaning it handles motoring and regenerative braking in both directions of rotation — typical for overhauling loads like unwind stands, hoists, or test benches where energy recovery is part of the cycle.
Sound level is listed at 82 dB(A). That's the audible noise under rated load from the cooling fans and magnetics — relevant for plant siting if the converter lives near an operator station or in a noise-controlled area. Auxiliary terminals carry an IP00 rating per IEC 60529 and IEC 60947-1 — meaning no ingress protection at the terminal block level. The main enclosure will have its own IP rating, but the aux connections expect to be inside a cabinet or otherwise protected from dust and moisture. Operating humidity range is 5 to 95% RH, non-condensing.
Analog I/O onboard
The converter comes with 3 analog inputs and 2 analog outputs as standard. These are available for speed reference, torque limit, or process feedback signals without needing an additional I/O module — useful for a standalone drive installation where the PLC connection is over fieldbus.
