The Allen-Bradley 1395-B73-C2-P10-X1 Digital DC Drive is a regenerative microprocessor-based DC digital drive in the Allen-Bradley 1395 Digital DC drive series, which provides digital control for industrial motors in applications requiring speed control. It features a fused AC input for line protection, programmable functions (current limit, acceleration, and pre-set speed), field performance regulation of up to a 6: 1-speed range, and it has in-built protection. The 1395-B73-C2-P10-X1’s operating voltage range is 150 to 460V AC with an input tolerance of -/+10% at 50-60Hz, and it has a drive power rating of 50HP. It provides a DC voltage output of up to 500V DC, with a selectable field voltage range of 240 to 300V DC, and also an adjustable field current range of 150mA to 10A. The 1395-B73-C2-P10-X1 offers a 6: 1-speed range field control with an encoder, and it produces a 6-pulse control waveform for output control. It has a programmable overload capacity of 150% for 60s, 200% for 10s and 260% for 5s, and it also offers programmable high DI/DT protection, instantaneous overcurrent trip, and motor overload protection. The 1395-B73-C2-P10-X1 has 0.01% control performance across a 10: 1-speed range, with a 0.001% speed regulation, across a 100: 1-speed range, and it uses a 12V, 500mA incremental/dual channel encoder with a 102.5 KHz transmission frequency and 50% (± 10%) duty cycle.

It offers 2 programmable, independent acceleration and deceleration times, 5 programmable pre-set speeds, 2 programmable hog speeds, 10 programmable/adjustable Moto Operated Pots (MOP). The 1395-B73-C2-P10-X1 has a 40 to 60 HP standard contactor, and it has a single-phase 115V AC control voltage. It also has a discrete adapter bard (Port A) option with four 115V AC digital inputs, 2 digital discrete outputs, 4 programmable 12-bit analog inputs, and 4 programmable 11-bit analog outputs, which are all pre-configured for various operational signals, and it has a standard auxiliary contact on the motor contactor for special interlocks (1 – N.O., 1 – N.C.). It has an 11V AC external output configured for costing to a stop, and it communicates via an external RS-422 programming terminal. The 1395-B73-C2-P10-X1’s operating temperature range is 0-55°C (32-130°F) at 5 to 95% relative humidity, and it is designed for installation at a maximum height of 1000m above sea level. It weighs approximately 45Kg and has total shipping dimensions 302.2mm x 279.4mm x 571.5mm.
