The Allen-Bradley/Rockwell Automation 1391B-AA45 controller is a pulse width modulated servo controller from the Allen-Bradley AC Servo 1391 series. It supports the highest current ratings available in this series (45 Amps continuous and 90 Amps peak), but it is the same compact size as all of the other AC Servo 1391 series controllers, which makes it easy to install. Its inputs are protected from transient voltage and it has a built-in circuit breaker that can open all 3 of the controller?s AC line leads when the power circuitry short circuits. The 1391B-AA45 controller also comes with a power bus supply module that is rated at 300 Volts DC and that has an internal shunt regulator. This controller can tolerate up to 95% relative humidity without condensation and its maximum operating temperature rating is 140 degrees Fahrenheit.

The 1391B-AA45 pulse width modulated servo controller by Allen-Bradley is an AC single axis servo controller, which provides maximum operational motor speed without loss of torque, thereby achieving greater precision and increased productivity. It has a nominal BUS output voltage of 300 Volts AC, with a continuous (RMS) current of 45 Amps that peaks at 90 Amps. The 1391B-AA45 has a power output rating of 15kW which peaks at 30kW, and is designed with a circuit breaker rated at 38 Amps (RMS), and can protect its circuit for up to 30 Amps before the interruption.
The 1391B-AA45 has a maximum drift of 0.07 RPM per degree Celsius and a dead-band of zero. It has an integral fan output of 50 CFM and a maximum short circuit current of 1300 Amps around a transformer input tolerance of +10% and -15%. The 1391B-AA45 has a power dissipation per percentage output of 104W at 20%, 208W at 40%, 312W at 60%, 416W at 80% and 520W at 100% power outputs. It has an operational temperature range of 32 to 140 degrees Fahrenheit at 5 to 95% non-condensing relative humidity and it will retain optimum performance at an altitude of 3300 feet. It weighs 34 pounds, and it has dimensions of 19.0 x 6.2 x 10.64 inches.
