A Digital AC Servo Drive from Allen-Bradley, the Bulletin 1391 unit listed here carries catalog number 1391-DES45-DI and is part of the 1391-DES series of microprocessor-based, single-axis pulse width modulated AC servo drives. The front panel features an integral LCD display with two lines of 16 characters, a 5-button keypad for local parameter configuration, and LED status indicators for Status and Enable conditions.
Nameplate data confirms an AC input of 230V, 3-phase, 50/60 Hz at 38 amps, with a control transformer input of 36V, single-phase, at 5.5 amps. AC output is rated 210V, 3-phase, 0 to 200 Hz, 45 amps, 14 kW. Maximum symmetrical RMS short circuit current is 1300 amps. Per manufacturer published specifications for this series, the nominal DC bus output voltage is 300V, with 45A continuous RMS current and 90A peak current, corresponding to 15 kW continuous and 30 kW peak output power.
The 1391-DES45-DI includes an integrated circuit breaker, an integral shunt regulator as part of the standard 300V DC power bus supply, a shunt regulator resistor, and a power line and dynamic braking contactor. The drive is designed for single-axis closed-loop positioning applications and is typically paired with Allen-Bradley 1326 series AC servo motors. Operating temperature range is 0 to 60 degrees Celsius with non-condensing humidity tolerance between 5 and 95%. The serial number visible on the nameplate label is ME4E50Y7. This unit was manufactured in the USA and is discontinued by the original manufacturer.
