20DD011A3QYNA3NBA

The 20DD011A3QYNA3NBA model is a versatile adjustable frequency AC drive produced by Allen-Bradley, a well-known brand under Rockwell Automation. This unit is intended for three-phase applications and operates efficiently at 480V AC. It has a maximum normal-duty current capability of 11 amps, making it suitable for various industrial settings requiring reliable motor control.

Housed in an IP20-rated enclosure that complies with NEMA Type 1 standards, this drive is designed for use in locations with moderate environmental exposure. A key feature of the device is the full numeric LCD, which serves as the human-machine interface, enabling straightforward monitoring and control.

The absence of included documentation means users should be prepared to perform initial setups independently. Additionally, the drive employs IGBT technology for braking, ensuring smooth and effective performance. An adjustable bus undervoltage trip is incorporated to prevent operation under unsafe conditions.

Monitoring of thermal performance is handled by a heat sink thermistor, which the integrated microprocessor checks to avoid overheating issues. Resilience is built into the design, offering a logic control ride-thru capability of 0.25 seconds when the drive is not executing tasks, and a power ride-thru function ensures operation can continue for 15 milliseconds while under full load. Overall, the 20DD011A3QYNA3NBA drive is engineered for stability and safety in demanding environments.
