Product Description
Other Models

The Allen-Bradley 1391-150ET has a 240/380/415/480V AC Primary Voltage, 3 Phases, and a 50/60 Hz Frequency. It also contains a 230V AC Single-Phase C.T. Windings Secondary Voltage. The 1391-150ET servo controller is part of Allen-Bradley's 1391 series of AC servo controllers. It has input protection against transient voltages, a power line contactor with a shunt regulator across the DC bus, a 300-Volts DC power supply, and a shunt regulator resistor.

This controller uses 3-phase voltage ratings of 240, 380, 415, and 480 Volts AC at 60 Hertz and has a 15 kVA rating. It also uses a 230-Volts AC secondary voltage and 36-Volts AC single-phase voltage.

The 1391-150ET servo controller mainly controls the speed and torque of an AC servo motor in a closed - loop system. Speed variances are done smoothly to prevent servo motor wear and damage.

For installation, use cables rated for at least 75 degrees Celsius. The wiring between controllers and motors should not exceed 15.2 meters, as longer cables may cause voltage drops. Install the servo controller on a flat, rigid vertical surface, leaving at least 7.9 millimeters of clearance on each side for ventilation. Otherwise, the controller may overheat, leading to operational failures and a shorter operating life.
