20DD3P4A3NYNANDNL

The 20DD3P4A3NYNANDNL model from Allen-Bradley is an adjustable frequency AC drive, suitable for three-phase setups with a voltage rating of 480V AC. This device is capable of handling a normal-duty current of 3.4 amps, which makes it effective for various industrial applications.

Its design includes an IP20 enclosure that meets NEMA Type 1 standards, offering essential protection in suitable environments. The unit comes with a full numeric LCD for monitoring and control, providing users with necessary operational data. However, it does not include any documentation.

For braking, the drive is equipped with IGBT technology, which enhances operational efficiency. Additional safety features include an adjustable bus undervoltage trip that allows customization to meet specific application needs. The thermal management of the drive is facilitated by a heat sink thermistor, which is monitored by a microprocessor to prevent overheating by triggering an overtemperature trip when necessary.

To ensure operational stability, the drive incorporates a logic control ride-thru function lasting up to 0.25 seconds when not in operation, helping to maintain system integrity during brief power fluctuations. Moreover, it offers power ride-thru for 15 milliseconds under full load, which aids in preventing disruptions during minor power disturbances. The 20DD3P4A3NYNANDNL thus represents a reliable option for demanding motor control applications.
