20DR180A0NNNA1NNA

The Allen Bradley part number 20DR180A0NNNA1NNA represents an adjustable frequency AC drive designed to operate at a voltage rating of 650V DC. This drive is configured for three-phase systems, supporting an input current of up to 180 amps. Its design reflects robust industrial applications capable of handling significant motor loads efficiently.

Housed within an enclosure rated IP20 to NEMA Type 1 standards, this unit is suitable for environments where dust and moisture are limited. However, it does not include a human-machine interface, as indicated by its blank cover, thereby simplifying the unit's exterior design. Documentation for this model is not provided.

The drive lacks a braking feature, which may be a consideration for specific applications. It is equipped with an adjustable bus undervoltage trip, allowing for customized operational parameters to prevent potential damage during low voltage conditions. Furthermore, thermal management is addressed with a heat sink thermistor, which is actively monitored by a microprocessor to ensure safe operating temperatures.

In terms of power stability, this device maintains logic control ride-thru for up to 0.25 seconds when it is not actively running. For brief power interruptions, it also possesses a power ride-thru capability lasting up to 15 milliseconds while under full load conditions, which is crucial for maintaining consistent motor performance in fluctuating operational environments.
