1391B-ESAA15

The 1391B-ESAA15 controller is an AC servo controller device. The device is designed and manufactured by Allen-Bradley. The servo controller device is used to power and manage the performance of electric servomechanisms. The device helps to amplify a servo’s performance by adjusting the velocity, torque, and position of the servo motor. This variant has an extended speed range of second position speed capability. The device has a rated nominal bus output voltage of 300 Volts DC. The device has a continuous RMS current of 15 Amps under normal loading conditions. The 1391B-ESAA15 controller also has 30 Amps peak current along with 5 kilowatts of continuous output power. The controller is mostly used in industrial and manufacturing plants and it is known for its robust performance and reliability.

The 1391B-ESAA15 controller is a series B device and it is conformally coated on the outer surface. It is manufactured compactly and it weighs only 22 pounds. The device has a circuit breaker interrupt rating of 1300 Amps and the input circuit breaker rating of the device is 17 Amps (RMS). The device is manufactured in such a way that the static gain of the device is 1.5 times the rated motor current. The device can regulate speed at up to 0.05% of the maximum motor speed when the device is applied with a 95% load. The operating temperature of this servo controller lies between 0 and 60 degrees Celsius. The storage temperature of the 1391B-ESAA15 controller ranges from 0 to 65 degrees Celsius. The servo controller is equipped with a feedback encoder which is connected to the main controller board. This device is usually used with a computer-aided closed-loop positioning system to control the position and the linear or rotary motion of different automation machines.
