The Allen-Bradley 22B-E4P2N104 is a robust PowerFlex 40 Variable Frequency Drive designed to efficiently control the speed of AC motors by modulating frequency. Featuring advanced Sensorless Vector Control, it delivers precise current regulation and supports Variable Pulse Width Modulation, enhancing output even at reduced frequencies. With a 3-phase input voltage range of 460-600VAC and an output power of 2.2 kW, it integrates an Integral PID controller for autonomous loop regulation and supports critical programming functions such as Timer, Counter, Basic Logic, and StepLogic. Constructed for versatile installation via DIN rail or direct panel mounting, it facilitates compact panel designs through zero stacking and effective RS485 communication for daisy-chain networking. Operating reliably within temperature extremes, this drive requires input fuses or circuit breakers for short circuit protection and is optimized for industrial environments, avoiding residential installations due to potential interference issues.
