20F14ND361JN0NNNNN

The 20F14ND361JN0NNNNN from Allen Bradley, part of the PowerFlex 753 series, is a variable frequency AC drive that excels in motor management. With a rated output current of 361 A and a power capacity of up to 300 horsepower for normal duty applications, this drive provides robust performance for various industrial tasks.

This model supports Safe Torque-Off (STO) utilizing a hardwired safety input, enhancing operational safety. It is adaptable with three available option slots that can accommodate different feedback, safety, or communication modules, promoting versatility in configurations.

Motor control in this drive is managed through several modes including V/Hz, Sensorless Vector, Flux Vector, and Permanent Magnet Motor Control, allowing for enhanced performance customization based on requirements. The unit is designed for vertical mounting and can be installed in either a cabinet or an open setup.

Operating in standard conditions, the drive functions effectively within a temperature spectrum of 0 to 40 °C and dissipates a significant 4015 watts at full load. Adequate cooling is provided by an air-cooled system featuring a heatsink fan, requiring an airflow of at least 756 CFM (1285 m³/h) for efficient heat management.

It does not include a dynamic braking system, as no internal transistor or resistor is present. However, integrated filtering with a common mode capacitor connection ensures reliable operation. The device itself is housed in an IP20/IP00 rated enclosure, compatible with NEMA/UL Type Open specifications, assuring protection adequate for typical installation environments. With a frame size of 700%, this drive embodies industrial standards suited for precise motor control applications.
