The Allen-Bradley 1391B-AA22 is a robust Pulse Width Modulated (PWM) Servo Controller designed for precise single-axis motor control in automated systems, integrating seamlessly with 1326 permanent magnet AC servomotors. This device efficiently transforms a three-phase 50/60 Hz input into variable AC voltage, enabling refined modulation of motor speed and torque. The controller supports a peak output power of 15 kW and a continuous output current of 22.5A, with a peak of 45A, while maintaining 85% efficiency. Engineered for panel mounting, the system features an open-frame design with a slide-on cover and includes an integrated fan to manage heat. The 1391B-AA22's input requires an Allen-Bradley 1391 isolation transformer to preserve its UL listing and ensures stable functionality across environments operating up to 1000 meters in altitude without performance degradation, making it ideal for applications demanding reliable and adaptable motor control solutions.
