20BD156A3AYNANN0

Part number 20BD156A3AYNANN0 is part of the Allen Bradley PowerFlex 700 range, representing a robust adjustable-frequency AC drive tailored for three-phase systems. This device functions efficiently with an input voltage of 480 V AC and is optimized for 60 Hz operations, delivering a precise output current of 156 A.

With a powerful motor capability of 125 HP, this drive can provide peak output currents of 188 A for up to one minute and 250 A for quick bursts of three seconds, making it suitable for demanding applications. The DC bus voltage hovers around 648 V DC, ensuring reliable performance, while the overvoltage trip is set near 810 V DC and the undervoltage limit around 305 V DC, contributing to operational safety.

The drive’s carrier frequency can be adjusted between 2 and 10 kHz, allowing flexibility in performance characteristics. Encased in an IP20 / Type 1 enclosure, it is designed for environments that require basic ingress protection without complex insulation.

Cooling is managed through an air-cooled system using a zero-stack mount, optimizing space while maintaining airflow. An input current is approximately 147 A, ensuring the drive is well-suited for extended operational periods. For dynamic braking, a built-in IGBT transistor facilitates effective energy management during deceleration. Control capabilities include V/Hz, sensorless, and vector modes, with operating frequencies reaching up to 420 Hz, adapting to various load conditions.
