20DD3P4A3EYYACNNA

The 20DD3P4A3EYYACNNA from Allen-Bradley is an adjustable frequency AC drive optimized for industrial applications. This model operates on a voltage of 480V AC and is designed to manage three-phase power systems efficiently. It features a normal-duty current rating of 3.4 amps, providing reliability in diverse operational scenarios.

Housed in an enclosure compliant with IP20 and NEMA Type 1 rating, this drive is well-equipped to handle indoor environments where basic protection is needed. A full numeric LCD operates as the human-machine interface, allowing operators to easily configure and monitor settings.

The drive incorporates an IGBT braking system, which enhances performance in dynamic motor control applications. Safety is further emphasized with an adjustable bus undervoltage trip, which provides necessary settings for specific operational conditions.

A microprocessor supervises the system's thermal management, continuously monitoring the heat sink thermistor. This feature helps prevent overheating by enabling an overtemperature trip.

For operational continuity, the logic control ride-thru function allows the controller to maintain performance for 0.25 seconds when not actively running. In addition, the power ride-thru feature supports a brief duration of 15 milliseconds under full load, ensuring stability during transient power interruptions.
