20DD500ACENNBEASE

The 20DD500ACENNBEASE adjustable frequency AC drive by Allen-Bradley is designed to meet the rigorous demands of industrial environments. This unit operates on a voltage supply of 480V AC and is configured for three-phase systems. It supports a substantial input current capacity of 500 amps, providing robust performance for various applications.

This AC drive features an IP20-rated enclosure, which ensures adequate protection in less harsh conditions. A full numeric LCD serves as the human-machine interface, which is mounted on the door for easy access and monitoring. Documentation provided includes a quick start guide to facilitate installation and operation.

The drive does not include a braking feature. However, it comes with an adjustable bus undervoltage trip, enhancing safety and adaptability during operation. Furthermore, for thermal management, the heat sink thermistor is monitored by a microprocessor to prevent overheating.

To optimize performance during brief power interruptions, the drive offers a logic control ride-thru capability of up to 0.25 seconds while in a non-active state. Additionally, it is equipped to maintain power for 15 milliseconds at full load, ensuring reliability in fluctuating load conditions. The 20DD500ACENNBEASE model is a key component in applications requiring adjustable frequency drives with high operational demands.
