The DCS880-S02-0300-05 is a fully controllable DC motor drive (converter) in ABB's DCS880 series, designed for 300 A output current to DC motors. This modular DC drive operates on a three-phase AC supply (up to ~525 VAC) and provides a DC output up to 500 V for armature circuits. It is a 4-quadrant (4Q) regenerative drive, meaning it can control motor speed/torque in both directions and return braking energy to the supply when decelerating. The drive delivers approximately 130–150 kW of motor power (around 175 HP) depending on supply voltage (e.g. ~142 kW at 400 V AC). The DCS880-S02 module is typically mounted in a control cabinet (frame size H2) and includes built-in cooling fans, fuses, and a field exciter output for the motor's field winding. It interfaces with ABB control panels or PLCs via standard protocols and features advanced control functions like field flux optimization and adaptive programming. Key safety features include safe torque off (STO) when combined with appropriate modules. The drive's dimensions are roughly 370 mm H × 270 mm W × 271 mm D, with a weight of ~16–18 kg. Engineered for heavy-duty industrial use, the DCS880 300 A drive offers robust performance in applications such as rolling mills, hoists, battery charging, or any DC motor-based process, with full PROFIBUS/Modbus/Ethernet connectivity options and compliance to IEC and UL drive standards.
