20F14ND302AA0NNNNN

The Allen Bradley part number 20F14ND302AA0NNNNN represents a versatile variable frequency AC drive within the PowerFlex 753 series. Designed for optimal performance, it requires a DC input with precharge functionality and has a notable voltage rating of 480 VAC along with a DC rating of 650 V. This drive supports a maximum current of 302 Amps, ensuring it can handle substantial loads efficiently.

The unit operates on a 3-phase configuration, which is essential for many industrial motor control applications. In terms of power ratings, it is capable of delivering up to 250 horsepower in normal duty operations. The drive does not include a door-mounted Human Interface Module (HIM), so control interfaces must be managed through other means.

For mounting purposes, the drive is compatible with flange mounts, facilitating installation within various setups. The frame size is classified as size 7, which indicates its physical specifications. An air cooling system aids in maintaining operating temperatures, contributing to reliable, continuous operation.

Filtering is included for effective signal integrity, helping reduce electrical noise. This device has an open-style enclosure rated at IP20/IP00 and is compliant with NEMA and UL type standards. It's important to note that the common mode capacitor jumper is removed, and the internal transistor supports dynamic braking functionality, while an internal resistor is not present. Overall, the 20F14ND302AA0NNNNN serves as a capable component for many variable speed applications, effectively managing and controlling motor behavior.
