20DD385BCENNBCASE

The part number 20DD385BCENNBCASE from Allen-Bradley is a powerful adjustable frequency AC drive specifically constructed to accommodate three-phase operations at 480V AC. With an impressive normal-duty current capacity of 385 amps, this device is adept at managing substantial electrical loads with ease. Housed in a durable enclosure rated IP20 and complying with NEMA Type 1 standards, the internal components are safeguarded against dust and moisture, making it suitable for regular industrial settings. A conformal coating adds an additional layer of protection against environmental factors.

This drive does not include a braking system; however, it features an adjustable bus undervoltage trip functionality, allowing for custom configurations to meet specific operational requirements. The heat sink thermistor, crucial for thermal management, is monitored by an embedded microprocessor, which will trigger a protective shutdown when overheating is detected, preserving the unit's integrity over time.

For reliability during power fluctuations, the 20DD385BCENNBCASE provides a logic control ride-thru capability of 0.25 seconds when the drive is idle. Additionally, it ensures continuity of operation with a power ride-thru time of 15 milliseconds at full load, thereby minimizing disruption in critical applications. A quick start guide is provided, facilitating straightforward installation and setup.
