Product Description
Allen-Bradley 1391B-ESAA45-AQB Bulletin 1391 AC servo controller, serial number MEAA0NU8, instruction manual 1391ES-5.0. The nameplate lists an AC input of 230 V, 3 phase, 50/60 Hz at 38 A, a control transformer input of 36 V, 1 phase, 50/60 Hz at 5.5 A, a maximum symmetrical RMS short circuit current of 1300 A, and an AC output of 210 V, 3 phase, 0-200 Hz at 45 A and 14 kW. The nameplate is marked made in USA, and the series letter at the edge of the label is cut off in the photo.
The front panel carries eight status indicators (overtemperature, power fault, control power, overvoltage, undervoltage, current foldback, run enable and drive ready) and a velocity offset adjustment. A cooling fan with a guard is visible below the nameplate. A St. Lawrence Electronics repair sticker with job number 73485 is on the front, so the unit has had third-party service. The dates on the sticker are only partly legible.
The front panel shows scuffs, tape residue and peeled label marks. Sold as surplus, untested; this controller has not been powered on or functionally tested by MRO Exchange. Buyers should confirm the catalog number, voltage and feedback configuration against their application before purchase.
