1397-B300R-HAB

The Allen-Bradley 1397-B300R-HAB DC drive is a 460 Volts AC regenerative version of the Allen-Bradley 1397 DC drive with an output power rating of 300 Horsepower (224 kW). It is ideal for applications with constant motor braking, accelerating, and decelerating, such as electrical cranes, downhill conveyors, electrical hoists, and electrical elevator applications where the operational requirements mean the motors should be started and stopped at regular intervals. Motors in those applications tend to act as generators while braking since the load they carry usually prevents sudden stops, making the motors generate surplus voltages (or regenerated voltages) that are then forced back to the drive’s DC Bus. Installing a regenerative DC drive like the Allen-Bradley 1397-B300R-HAB drive offers the possibility of recovering those surplus voltages for re-utilization, instead of wasting them as heat, and this contributes to energy efficiency.

Operators and maintenance crews can control the Allen-Bradley 1397-B300R-HAB DC drive locally or remotely by using the built-in keypad or by connecting external devices to the terminals at the regulator board terminal strip. When installing the drive, arrangements should be made to place it in a dry and clean location, with a temperature range from 0 to 55 degrees Celsius (32 to 131 degrees Fahrenheit). For drives that are installed in enclosed cabinets, using forced air circulation through fans or a closed-circuit cooling control system may be required. Given the open chassis type of construction of the 1397-B300R-HAB DC drive, it is necessary to place it inside a suitable enclosure after all the mechanical work that is needed to physically install the drive has been completed to avoid any metal particles entering the drive’s circuitry.
