The 1395-B77-D4-P50-X1 drive is one of the drives from the 1395 drive series by Allen-Bradley/Rockwell Automation. This digital drive is part of Series B of the 1395 drives and it is built on advanced microprocessor technology. The product series offers armature regenerative and non-regenerative drive variants that are available in several different power ranges. The wide variety of drives helps the machines to meet the specific requirements of different applications. The 1395 drives include standard features such as field regulation over a 6 to 1 speed range, an adjustable current limit, programmable and preset speeds, and adjustable acceleration and deceleration settings. The 1395-B77-D4-P50-X1 drive comes with a dynamic braking contactor and it includes optional elements such as node adapter in Port B and an auxiliary contact. Other available options that are not included with the drive are a discrete adapter, a digital reference adapter, a multi-communications adapter, and a ControlNet adapter. The 1395 drives offer a multitude of functionalities for communication and additional machine control.

The 1395-B77-D4-P50-X1 drive operates on 460 Volts AC input voltage and it must be 3-phase. The drive has an input frequency of 50 to 60 Hertz and a power output rating of 125 Horsepower. In addition to that, the output voltage of the drive is 500 Volts DC. The 1395-B77-D4-P50-X1 drive features field current range of 650 milliAmps to 20 Amps (continuous) and a maximum power dissipation rating of 675 Watts. Also, it should be mentioned that the drive is a regenerative drive. Even though the 1395-B77-D4-P50-X1 drive is built for tough industrial conditions, it should only be used or stored in a clean and dry environment with an ambient storage temperature range of 0 to 65 degrees Celsius (32 to 149 degrees Fahrenheit).
