3ADT218567S0126 ABB DCS880-S01-2600-10R DC Converter, 2600 A

The 3ADT218567S0126: Frame H8 is the physical envelope — it determines the mounting footprint, busbar spacing, and cooling duct layout. If you're replacing an existing H8-frame converter, this drops in; if you're designing new, the cabinet cutout and ventilation must match the H8 dimensions (check the mechanical drawing against your gland plate). The 2600 A continuous rating is the DC output current at the rated 990 VAC supply. The 2Q topology handles motoring and regenerative braking in one direction only. Three analog inputs and two analog outputs are available for speed reference, torque limit, or process feedback loops. That's typical for a drive of this class — you get one AI for speed setpoint, one for current limit, one spare; the AOs can feed a PLC or local meter. No fieldbus module is listed in the base spec, so if you need PROFINET or EtherNet/IP, plan for an option slot. Sound level is 82 dB(A) — that's audible on the plant floor. If the drive is near a quiet zone or operator station, budget for an enclosure or remote mounting. The IP00 rating on the auxiliary terminals means they're not protected against dust or touch; the converter itself requires an IP54 or better cabinet in industrial environments. Operating humidity range of 5 to 95% RH covers most non-condensing indoor conditions. No derating needed for high-humidity areas like washdown zones, as long as the cabinet stays above dew point.
