Need a Specific Revision?

The 1397-B125N from Allen Bradley is a digital DC drive engineered to operate at 460 VAC and deliver a power output of 93 kW. This device functions as a non-regenerative drive, supporting both 50 and 60 Hz nominal line frequencies while managing armature and field voltages of 500 VDC and 300 VDC, respectively. It is designed with a continuous service factor of 1, making it suitable for consistent load demands. Users should ensure the load remains above 5% of its rated capacity for optimal performance. This drive can be installed at altitudes up to 3300 feet and operates reliably in environments with relative humidity levels ranging from 5% to 95%, provided they are non-condensing. The chassis temperature of the device can reach 55°C, while the maximum allowable temperature in the cabinet is limited to 40°C.

The Allen Bradley 1397-B125N is a digital DC drive characterized by its robust configuration. It is capable of operating at an input voltage of 460 VAC and provides a total power capacity of 93 kW, placing it in a suitable range for various industrial applications. As a non-regenerative drive, it enhances control over motor functions without returning energy to the supply. Designed for versatility, this drive works at a nominal line frequency of either 50 or 60 cycles per second, enabling its use in different electrical environments.

When addressing armature and field voltages, this model is rated at 500 VDC and 300 VDC, respectively, which ensures effective motor performance in demanding tasks. The service factor of 1 continuous signals its capability to sustain operations without overheating or compromising system integrity.

To maintain effective operations, a minimum load of 5% of the drive’s rated capacity is essential. This allows the 1397-B125N to function optimally within specified parameters. Suitable for elevations up to 3300 feet, this drive can adapt to various installation sites without loss of performance. Additionally, it supports a wide humidity range from 5% to 95% under non-condensing conditions, solidifying its reliability in diverse industrial environments.

Thermal management is significant for this drive, with a maximum ambient temperature of 55°C for the chassis and 40°C for installations within cabinets, ensuring long-term durability. The 1397-B125N drive exemplifies efficiency and performance within the digital DC drive category.
