The Allen-Bradley 1397-A075N-HA2-L11 is a non-regenerative 1397 series digital DC drive. Equipped with an I/O expansion cord and a programmer/controller human interface option with a digital pot, this drive has a 230V AC input voltage rating with 75 HP and 55 kW, with a frequency variation of +/- 2 cycles of the nominal frequency and a nominal line frequency of 50 or 60 cycles per second. The full-load rated RMS AC line current of the 1397-A075N-HA2-L11 drive is 226 A and it also has a minimum source of 93 kVA and 25,000 A power source capacity. Note that the AC line of this drive is capable of handling up to 3 drives in a transformer. For the 1397-A075N-HA2-L11 drive’s rated load and speed, it has an 88% typical displacement power factor and a 98.6% drive efficiency for the drive only, as well as a typical drive efficiency for the drive and the motor of 85%. This drive also has a continuous service factor of 1 and a minimum load of 5% of the drive’s rated load. Its drive-only overload capacities depend on the length of time. These capacities, in terms of the full load rating, are 150% for 1 minute and 200% for 13 seconds. This three-phase drive should only be placed in a location without extreme temperatures, dust, caustic or acidic vapors, interference (both electrical and electromagnetic noise), dirt, shock, or vibration. Make sure to operate the 1397-A075N-HA2-L11 drive only at room temperatures of 55°C or less when placed in a chassis or temperatures of 40°C or less when placed in a cabinet.
