Allen-Bradley 1391B-AA45N AC Servo Controller

The Allen Bradley 1391B-AA45N is a Servo Controller drive that is part of the 1391 product family. It has a rated Input voltage of 240 VAC, 3-Phase with an output current of 45.0 RMS Continuous and peak current of 90.0 amperes. It also has an output power of 15.0 kW with peak output of 30.0 kW. This servo controller has an Open Frame with internal Heat sink.

The Allen-Bradley 1391B- AA45N is part of the 1391 Servo control product family. Servo controllers interface with servo motors to control motion and position, and they are mainly utilized in manufacturing and production processes.

Servo controllers rely on encoder feedback to determine the current position of the controlled mechanism in both linear and rotary motion control applications. They are commonly installed in production conveyors, pick - and - place robotic arms, and rotary lathe machines.

This Allen-Bradley 1391B- AA45N servo controller has a form factor of no more than 1.03, and its peak current limit can be adjusted within 20 to 200% of the rated motor current. The minimum efficiency of the controller at the rated load is 85%, and its modulation frequency is ±2500 Hz.

 Allen-Bradley 1391B- AA45N has an open frame, and the internal components are covered by a slidable front cover. Appropriate enclosure protection must be installed to safeguard the drive from environmental interferences and contaminants. Consider whether a climate - control component, such as a fan or a heater, should be installed. If the enclosure is vented with ambient air, filters must be installed to prevent damage caused by the entry of oil, dust, condensation, and other contaminants.
