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.
