The Allen-Bradley 1391B-ESAA45-AQB is an AC servo controller/amplifier with a single axis and a quad encoder output. This 3-phase controller has an input power of 230V, 38 A, and a line frequency of 50-60 Hz. Its output power is 210V AC, 15 kW at 0-200 Hz. Its RMS output current is 45 A when continuous and 90 A at peak. The nominal bus output voltage of the 1391B-ESAA45-AQB controller is 300V DC.

Newer 1391B-ESAA45-AQB controller/amplifier can avoid backlash with the 1388 Anto-Backlash module and they can accelerate or decelerate linearly with a manual CR-APG-001 control module that uses 1-4 preset speeds.

The 1391B-ESAA45-AQB’s efficiency at its minimum rated load is as high as 85% and its modulation frequency is 2500 Hz at +/- 10%.

The 1391B-ESAA45-AQB can be stored or operated anywhere that has a relative humidity level no lower than 5% and no higher than 95%, and the humidity must be non-condensing. This AC servo controller/amplifier functions best at a temperature between 32 and 140 oF (0 and 60 oC), while it can be stored at a temperature as low as 32 oF (0 oC) or as high as 149 oF (65 oC). The 1391B-ESAA45-AQB also functions best at an altitude of 3300 feet or less. The controller/amplifier has an integral fan output of 50 CFM if the device is unloaded. It also has a deadband rating of 0.
