DC converter for high-current drives
The ABB 3ADT218567S0235 is a DCS880-S02-3300-08R DC converter in a 4-quadrant configuration, rated for 800 VAC input and 3300 A output. It sits in the H8 frame size and is listed at 82 dB(A) acoustic noise. Three analog inputs and two analog outputs are available for control-loop feedback or external setpoints. The unit is designed for 50 Hz line frequency.
The 3300 A continuous rating and 800 VAC input define the motor armature and field supply capability. The 4Q topology means regenerative braking is built in. Frame H8 dictates the mounting footprint and bus-bar layout.
This part carries an active lifecycle status, so it remains in ABB's current production portfolio. No last-time-buy or phase-out window is in effect.
Environmental and protection notes
The auxiliary terminals carry an IP00 rating per IEC 60529 and IEC 60947-1 — meaning no ingress protection at those connection points; panel builders must house the converter in a suitable enclosure.
