20DD156A0EYNANBNL

The 20DD156A0EYNANBNL adjustable frequency AC drive from Allen-Bradley operates at a voltage level of 480V AC. Designed for three-phase applications, this drive supports a maximum normal-duty current of 156 amps, making it well-suited for demanding industrial conditions. The unit is designed with an IP20 enclosure, conforming to NEMA Type 1 standards and providing adequate protection for internal components in typical indoor environments.

The unit features a blank cover for its human-machine interface, maintaining a streamlined design. The drive utilizes IGBT technology for braking, ensuring efficient operation and enhanced safety.

In terms of protective features, this model includes an adjustable bus undervoltage trip, which allows customization based on specific operational needs. Additionally, thermal management is implemented through a heat sink thermistor monitored by a microprocessor, which triggers an overtemperature trip if necessary.

Thanks to its logic control ride-thru feature, the drive can maintain settings for 0.25 seconds when not actively running. Furthermore, it provides essential power ride-thru capabilities, sustaining continuous operation for up to 15 milliseconds under full load conditions. Overall, the 20DD156A0EYNANBNL drive by Allen-Bradley is engineered for robust performance in various industrial applications.
