The model 20DC072A3NYNACNNN by Allen-Bradley is a versatile adjustable-frequency AC drive. It operates at a nominal voltage of 400V AC and features a robust design for three-phase applications. This drive delivers an impressive 72 amps of normal-duty current, making it suitable for a wide range of industrial tasks.
Housed in an IP20-rated enclosure, compliant with NEMA Type 1 standards, this unit is designed for use in non-harsh environments where dust and moisture exposure is limited. The human-machine interface consists of a full numeric LCD, allowing users to monitor performance easily; however, it is important to note that no documentation is included.
The 20DC072A3NYNACNNN's features include an IGBT braking system that offers efficient performance and control during operation. It also incorporates an adjustable bus undervoltage trip to safeguard against sudden voltage drops. The heat sink thermistor operates under a microprocessor's monitoring, ensuring protection against overheating conditions.
The drive's logic control allows for a ride-thru time of 0.25 seconds when it is inactive, while it provides power ride-thru capabilities of 15 milliseconds under full load. The various characteristics of the 20DC072A3NYNACNNN make it a robust solution for complex industrial motor control applications.
