Product Overview
The Allen Bradley 20BC260A3ANNAND0 PowerFlex 700 AC Drive is a premium Variable Frequency Drive (VFD) from the industry-proven PowerFlex 700 series. Designed for demanding industrial automation applications, this AC drive delivers advanced vector motor control, precise speed regulation, intelligent diagnostics, and comprehensive protection functions for medium- and high-power three-phase AC induction motors.
Designed for 380–480 VAC three-phase power systems with a 400 VAC nominal input, the 20BC260A3ANNAND0 provides a rated continuous output current of 260 A, supporting motors up to 132 kW (Normal Duty) and 110 kW (Heavy Duty). The drive continuously adjusts output voltage and frequency to maximize process efficiency, improve torque performance, reduce mechanical wear, and lower overall energy consumption.
This configuration features 24 VDC vector control I/O, no internal communication module, no Human Interface Module (blank front plate), no brake IGBT, no internal braking resistor, and an integrated EMC filter with a common-mode choke. Its modular architecture allows optional communication adapters such as EtherNet/IP, DeviceNet, ControlNet, PROFIBUS, or Modbus to be installed according to application requirements.
With overall dimensions of 976.3 × 403.9 × 275.5 mm and an approximate weight of 71.44 kg, the drive is designed for cabinet-mounted installations requiring reliable operation, efficient cooling, and simplified maintenance.
Typical applications include conveyor systems, pumps, compressors, mixers, extruders, fans, mining equipment, steel production, cement manufacturing, water treatment facilities, pulp and paper mills, chemical processing plants, and automated production lines.
