The ABB 3ADT218519S0221 is a DCS880-S02-0200-04 DC converter, a 4-quadrant unit rated for 400 VAC and 0200 A, in Frame Size H2. It carries 3 analog inputs and 2 analog outputs, operates at 50 Hz, and is rated for 5 to 95% RH. The auxiliary terminals are IP00 per IEC 60529 and IEC 60947-1.
Frame Size H2 determines the physical footprint and mounting pattern — verify panel cutout and busbar spacing against the installation manual. The 4Q designation means it regenerates braking energy back to the line. The 55 dB(A) sound level is the fan noise at rated load. The IP00 rating on the auxiliary terminals means they are not protected against solid objects or moisture.
Integration Notes
3 analog inputs and 2 analog outputs are available for speed reference, torque limit, or process feedback. The 50 Hz rating matches standard European mains.
