The Allen-Bradley/Rockwell Automation DC drive known as the 1395-B77-D4-P10-P54EN drive is made for industrial applications where machine reliability and performance are crucial. The unit has open chassis construction and it includes several protective features that will contribute to creating a safe environment for the operators of the system. The 1395-B77-D4-P10-P54EN drive is one of the available drives from the 1395 product family (Series B) and it includes features like fused AC input, a DC contactor, basic input/outputs, and programmable functions for adjusting speed. This UL listed and CSA approved component has a standard 1395 enclosure and dimensions of 864 millimeters (34 inches) in height, 394 millimeters (15.5 inches) in width, and 323 millimeters (12.7 inches) in depth. In addition to that, this robust drive has a weight of 74.8 kilograms (165 pounds).

The 1395-B77-D4-P10-P54EN drive is intended for systems that operate on DC power sources and it features an output voltage rating of 500 Volts DC. However, the input voltage of the drive is 460 Volts AC (3-phase) while its input frequency range is 50 to 60 Hertz. The output power rating of the 1395-B77-D4-P10-P54EN drive is 125 Horsepower. The unit has a field current range of 650 milliAmps to 20 Amps (continuous) and a power dissipation rating of 675 Watts. It is important to mention that the drive is a regenerative type of drive and it includes a contactor for dynamic braking. Since the 1395 product series offers numerous custom options that can be added, it should be noted that this drive variant includes an optional discrete adapter rated at 115 Volts AC that is installed in Port A of the drive and a ControlNet adapter board that can be installed in Port A or Port B of the drive.
