20DD180A3EYNARASE

The Allen-Bradley 20DD180A3EYNARASE is designed for precision in motor control applications and functions effectively as an adjustable-frequency AC drive. With a rated voltage of 480 volts AC, this drive is structured to work with three-phase systems. A normal-duty current capacity of 180 amps at the input allows it to manage significant load demands, making it a robust choice for various installation scenarios.

It is housed in an enclosure rated at IP20, which meets NEMA Type 1 specifications, thus providing adequate protection for indoor use. A full numeric LCD facilitates user interaction, allowing operators to easily monitor and adjust system parameters.

The drive operates without a braking system but implements an IGBT brake for improved operational control during performance. Additionally, it features an adjustable bus undervoltage trip to prevent operation under unsafe voltage conditions. A microprocessor monitors the heat sink thermistor, ensuring effective thermal management and trip activation in overtemperature scenarios.

This model includes a logic control ride-thru time of 0.25 seconds when the drive is not actively running, which is crucial for maintaining system stability during short power outages. Furthermore, it is capable of supporting power ride-thru for a duration of 15 milliseconds under full load, enhancing its reliability in critical industrial environments.
