20DD500A3NNNBNNNN

The Allen-Bradley 20DD500A3NNNBNNNN is a robust adjustable frequency AC drive specifically designed for industrial applications. It functions at 480 volts AC and is optimized for three-phase operation, providing high-capacity needs with an input current rating of up to 500 amps. This specification makes it highly effective for demanding environments that require reliable motor control.

Housed within an IP20 enclosure that meets NEMA Type 1 standards, this drive ensures adequate protection from dust and contaminants typical in industrial settings. It includes a full numeric LCD that facilitates user interaction, allowing operators to monitor and adjust settings easily. Notably, this unit does not feature any braking system.

This drive is equipped with an adjustable bus undervoltage trip feature, designed to safeguard the system during low voltage conditions. For temperature management, the drive incorporates a heat sink thermistor that is supervised by a microprocessor. This technology helps prevent overheating by triggering alerts when necessary.

In terms of operational reliability, the 20DD500A3NNNBNNNN supports a logic control ride-thru duration of 0.25 seconds while the drive is in an idle state. It also provides a power ride-thru capability of 15 milliseconds at full load, ensuring that performance is maintained even during brief power interruptions. Overall, this AC drive is engineered to meet the needs of high-performance industrial operations, providing essential functionalities and robust protection.
