The Allen-Bradley 22B‑D4P0N104 PowerFlex 40 VFD is a 1.5 kW (2 HP) variable frequency drive designed to regulate three-phase AC motors for adjustable speed, torque, and energy-efficient operation. It accepts 480 V AC three-phase input and delivers an output frequency range of 0–60 Hz with V/f control, enabling smooth speed regulation, soft start/stop, and integrated motor protection. Protection features include overload, overcurrent, overvoltage, and ground fault protection, with a keypad/display for parameter setup and monitoring and panel or enclosure mounting suitable for industrial environments. Standards compliance includes UL/cUL and CE where applicable, and it is rated for an industrial temperature operating range. Typical applications encompass pumps, fans, conveyors, mixers, compressors, and material handling equipment in manufacturing plants, HVAC systems, water/wastewater facilities, and packaging machinery where adjustable motor speed enhances efficiency. Common replacements listed for this model include Allen Bradley PowerFlex 525 2 HP VFD, PowerFlex 753 2 HP VFD, and Siemens SINAMICS G120 2 HP drive.
