The Allen-Bradley 1395-B71-C1-PZ Digital DC Drive is a variable speed DC digital drive in the Allen-Bradley 1395 Family of Digital DC drives, which provides microprocessor digital motor control in applications involving speed control. The drive features a fused AC input for line protection, DC contact, field regulation over a 6 to 1 speed range, and programmable functions. The 1395-B71-C1-PZ is a regenerative DC drive with a 3-phase operating voltage range of 150 to 460V AC at +/– 10% input tolerance, and it has a drive rating of 30 HP. The drive has a standard contactor, with a 2 to 30HP contactor rating, and it has an input real power range between 1.5 kVA and 660 kVA. It has a maximum output voltage of 500V DC, with a 2 to 200HP output, and it has a selectable output current range between 3.6A and 980A.

The 1395-B71-C1-PZ has a field output voltage of 240 to 300V DC, with a field output current range of 150mA to 10A, and it provides field control across a 6:1 speed range, using an encoder feedback device. The 1395-B71-C1-PZ uses the 6-pulse waveform for output control, and it has a programmable output overload capacity of 150% for 1 minute, 200% for 10s, and 260% for 5s. The drive offers 0.01% of the set output speed regulation across, and 0.001% of the top speed across a 100:1 speed range using an encoder feedback device, and it has 2% of the top-speed armature control. It has 24VDC/115VAC hard–wired external inputs, configured for Enable/Contingency control, and it has 1 Normally Open (NO) Relay output, configured for Drive Ready/Faulted. The 1395-B71-C1-PZ offers 2 programmable and independent Accel/Decl times, programmed from 0.1 to 6554s, and it has programmable drive functions (Pre-set speed, Jog speed, and S Ramp). It has an operating temperature range of 32 – 130° F at 5 to 95% non-condensing humidity, and it is built to remain operational at a maximum altitude of 3,300ft. It weighs about 45Kg, and it has shipping dimensions of 302.2mm x 279.4mm x 571.5mm.
