20DD180A3ENNA1NNA

The 20DD180A3ENNA1NNA is an adjustable-frequency AC drive from the Allen-Bradley PowerFlex 700S series, manufactured by Rockwell Automation. This unit provides reliable operation at 480 volts AC and is built for a three-phase configuration, accommodating a normal-duty current of up to 180 amps. It is effective in applications requiring robust motor control.

Constructed with an IP20 enclosure compliant with NEMA Type 1 standards, the drive is suitable for indoor environments where moderate protection is sufficient. The device features a full numeric LCD interface that allows users to monitor and adjust settings easily, enhancing user experience.

The 20DD180A3ENNA1NNA lacks a braking mechanism but compensates with an adjustable bus undervoltage trip feature. This flexibility permits users to tailor the drive's operational thresholds according to specific requirements. The heat sink is equipped with a thermistor, which is overseen by a microprocessor to activate an overtemperature trip when necessary, ensuring the unit's safety and reliability during operation.

Moreover, the drive includes logic control ride-thru functionality, sustaining operation for 0.25 seconds when the drive is not running. It also supports a power ride-thru duration of 15 milliseconds at full load, ensuring stability during brief power interruptions. Documentation includes a quick start guide, further assisting in the device's setup and operation.
