1391B-AA15

The Allen-Bradley 1391B-AA15 Servo Controller is a single-axis AC servo controller which provides industrial motors with the maximum operational speed without losing torque and while achieving greater machine precision and increased productivity. The 1391B-AA15 has 300V DC nominal BUS output voltage with 15A continuous output current which peaks at 30A and an output power of 5KW which also peaks at 10KW. The controller comes with a 17A RMS circuit breaker and has a 1300A circuit breaker interrupt. The 1391B-AA15 has 1.5 x motor-rated/RPM-rated electronic gain, and a form factor of 1.03 or lower. It also has a speed regulation change of 0.05% (max.) of the maximum motor speed with 95% load, and it has a load-dependent efficiency of 85%, with a carrier frequency range between 2500 Hz ±10%. 0.07 RPM /Degrees Celsius.  It has 0.07 rpm per Degree Celsius maximum drift, and with 0 dead-band. The 1391B-AA15 has an integral fan output of 50CFM, and a maximum short circuit current withstand of 1300A, around +10% and -15% transformer input tolerance. The controller has a power loss per percentage output power of 104W at 20%, 208W at 40%, 312W at 60%, 416W at 80%, and 520W at 100% power outputs. Its operational temperature ranges between 0 and 60° C (32 and 140° F) at 5-95% non-condensing relative humidity, and it can be successfully installed at a maximum height of 1000 meters (3300 feet) without de-rating. The 1391B-AA15 weighs 9.97Kg (22lb), and it has dimensions of 426mm x 157.5mm x 270.2mm (19in x 6.2in x 10.64in).
