The Allen-Bradley 20G11BD1K4JN2NNNNN is a PowerFlex 755 AC drive for the 480 V AC / 650 V DC class in frame 9, built as an IP20, NEMA/UL Type 1 MCC-style floor-mount cabinet 600 mm deep with AC input with precharge and DC terminals. Rockwell rates it at 1540 A and 1350 Hp for light duty, 1420 A and 1250 Hp for normal duty and 1135 A and 1000 Hp for heavy duty. This version has filtering with the common mode capacitor jumper installed, no internal dynamic braking transistor and a door-mounted enhanced LCD full numeric HIM (IP20). Floor-mount frames 8…10 include a DC link choke, integrated AC line fuses and a roll-out design; Rockwell specifies a roll-out cart for power wiring and cabinet mounting. The PowerFlex 755 is Rockwell's 750-Series drive for maximum flexibility and performance up to 2000 Hp and 1500 kW, with a built-in Ethernet port, slot-based option cards, DeviceLogix embedded control and a choice of safety options.
