The 1391B-AA15-A12 AC Pulse Width Modulated Servo Controller is a 15A 230V AC (3-phase) single-axis servo controller by Allen-Bradley with a rare-earth free propulsion motor option, used for generating the maximum motor operational speed without any loss of torque and for achieving greater machine precision. It has a nominal power supply BUS output voltage of 300V DC with an output current of 15A which peaks around 30A and it provides a 5kW output power, which can also peak at 10kW. The 1391B-AA15-A12 has an input circuit breaker rating of 17A RMS, with a circuit breaker interrupt with a maximum rating of 1300A, and it has 230V AC (3-phase) input voltage at 50-60Hz and a 36V AC control voltage from a 3-phase voltage with +10% to –15% input tolerance range.
It features 1.5 x motor rated per RPM rated electronic static gain with 1.03 or less as the form factor and it has a load-dependent adjustable peak current limits between 20% and 300%, with a load-dependent efficiency of 85%, and a carrier frequency range of 2500 Hz ±10%. The 1391B-AA15-A12 has a maximum drift of 0.07 rpm per degree Celsius with zero dead-band, and it has a 0.05% maximum speed regulation change interval with 95% load. The controller has 50 CFM integral fan output, and it dissipates 38W and 190W heat at 20% and 100% of the rated controller power outputs. It has a working temperature range of 0-60oC (32-140oF), at a relative humidity level of -95% with no condensation, and it is stored at a temperature range of 0-65 oC (32-149oF). It weighs about 9.97Kg (22lb), with net dimensions of 426mm x 157.5mm x 270.2mm (19in x 6.2in x 10.64in), and it is CSA-certified and UL-listed.
