The 20DD077A3EYNACNBN is part of the Allen-Bradley PowerFlex 700S series and functions as an adjustable-frequency AC drive. Tailored for three-phase operations, this drive accepts an input voltage of 480 volts AC and can handle up to 77 amps of normal-duty current, making it suitable for high-demand applications.

Encased in an IP20 enclosure, compliant with NEMA Type 1 standards, it has adequate protection for use in non-hazardous indoor environments. The human-machine interface is a full numeric LCD, which enables operators to access and manage operational settings with ease.

The drive incorporates an IGBT braking mechanism for motor control efficiency. An adjustable bus undervoltage trip feature enhances safety by meeting defined operational parameters.

Thermal management is maintained through a heat sink thermistor, which is continuously supervised by a microprocessor to prevent overheating incidents. The drive supports a logic control ride-thru of 0.25 seconds during non-operation periods, and it can sustain power ride-thru functionality for 15 milliseconds at full load, ensuring reliability in fluctuating power conditions or outages.
