20DD385A3ENNBEGNE

The 20DD385A3ENNBEGNE from Allen-Bradley is an adjustable-frequency AC drive. It operates on a three-phase system at 480V AC, allowing it to handle a considerable normal-duty current of up to 385 amps. Enclosed in an IP20-rated casing, it adheres to NEMA Type 1 standards, thus ensuring adequate protection in controlled environments.

A full numeric LCD facilitates user interactions, enabling easy access to drive parameters and monitoring. For safe operation, the unit incorporates an adjustable bus undervoltage trip feature, providing tailored settings for various requirements. However, it does not include an integrated braking system.

Thermal management is enhanced as the heat sink thermistor is continuously monitored by a microprocessor, which activates an overtemperature trip if necessary, safeguarding the drive. When the drive is not operational, it supports a logic control ride-thru capability of 0.25 seconds to maintain system integrity during brief power outages. Additionally, the drive is capable of maintaining power ride-thru for 15 milliseconds at full load, ensuring continuity of operations during transient voltage changes. Overall, the 20DD385A3ENNBEGNE is well-suited for applications requiring reliable motor control within industrial settings.
