The Allen-Bradley 20DD040A3EYNACNNN, part of the PowerFlex 700S series, is an adjustable-frequency AC drive intended for three-phase motor control applications. Operating at 480V AC, this drive can effectively manage a normal-duty current of up to 40 amps.
Encased in an IP20 housing conforming to NEMA Type 1 standards, this unit is designed for use in environments where minimal dust and moisture exposure is a concern. Its human interface machine is a full numeric LCD, allowing users to efficiently monitor and adjust settings.
Noteworthy functionalities include IGBT braking technology which enhances operational performance and responsiveness. The drive is also equipped with an adjustable bus undervoltage trip feature, allowing users to set specific thresholds tailored to their applications.
Thermal protection is managed through a heat sink thermistor that is actively monitored by a microprocessor, which engages an overtemperature trip if needed. Furthermore, the drive supports a logic control ride-thru of 0.25 seconds while not operating, ensuring minimal disruption during brief interruptions. Additionally, it has a power ride-thru capability lasting 15 milliseconds under full load, which helps enhance operation reliability during power fluctuations.
