Product Description

Allen-Bradley's 1391B ESAA45 is a Bulletin 1391 AC servo controller identified by catalog number 1391B ESAA45, confirmed on the unit's rating plate along with the Series D designation and serial number MEAD5ZS1. The controller accepts 230 VAC three phase input at 50/60 Hz with a 38 amp input rating, and delivers 210 VAC three phase output across a 0 to 200 Hz range at 45 amps continuous and 14 kW. A control transformer tap accepts 36 VAC single phase at 5.5 amps, and the maximum symmetrical RMS short circuit current rating is 1300 amps.

The front panel includes status indicators for overtemperature, power fault, control power, overvoltage, undervoltage, current foldback, run enable, and drive ready, along with a velocity offset adjustment. Buyers matching this exact catalog number for CNC servo axis replacement or spare inventory sourcing can reference the 1391B ESAA45 designation and Series D marking directly from the nameplate.
