20DD500A3ENNBDGNE

The Allen-Bradley 20DD500A3ENNBDGNE is a robust adjustable frequency AC drive tailored for demanding applications. It is engineered to handle a voltage of 480V AC while functioning in a three-phase environment. The drive supports a substantial input current of 500 amps, which makes it suitable for a wide variety of industrial machinery and processes.

This model is housed in an IP20 enclosure up to NEMA Type 1 standards, enabling installation in indoor conditions with moderate environmental exposure. Control and monitoring are facilitated through a full numeric LCD, allowing for intuitive user interaction. A quick start guide is included to streamline setup and ensure efficient deployment.

The device does not incorporate a braking feature; however, it compensates with an adjustable bus undervoltage trip setting, adding a layer of safety by preventing potential faults due to low voltage. Additionally, a heat sink thermistor is actively monitored by a microprocessor, which triggers an overtemperature trip if temperature thresholds are exceeded.

The logic control ride-thru feature allows the unit to sustain its logic for 0.25 seconds during periods when it is not operational, ensuring stability under transient conditions. For enhanced performance, the drive can maintain power ride-thru for up to 15 milliseconds at full load, which is crucial in preventing disruptions during brief power outages. The 20DD500A3ENNBDGNE remains a reliable choice for industries requiring precision and control in motor applications.
