20DD2P1A3NYNA1NBA

The 20DD2P1A3NYNA1NBA from Allen-Bradley is a sophisticated adjustable frequency AC drive engineered for precise control in three-phase systems. Rated for 480 volts AC, this device processes a modest input current of 2.1 amps, making it ideal for applications requiring efficiency and reliability.

The overall design includes an IP20-rated enclosure compliant with NEMA Type 1 standards, ensuring basic protection from internal and external conditions. Interaction with the drive is facilitated through a full numeric LCD, which provides users with clear operational feedback. It is important to note that there is no accompanying documentation included with this model.

The drive operates without an integrated braking mechanism, yet it features IGBT technology that ensures smooth performance. Additionally, the adjustable bus undervoltage trip enhances safety parameters significantly. The heat sink is equipped with a thermistor, monitored by a microprocessor that protects the device from overheating by triggering an overtemp trip when necessary.

Operational stability is further ensured by the logic control ride-thru feature, allowing the drive to maintain configuration settings for up to 0.25 seconds while not running. Furthermore, under full load conditions, the device can sustain power ride-thru operations for as long as 15 milliseconds, providing essential reliability in transient conditions.
