20DD034A3EYNA5NNA

The Allen-Bradley model 20DD034A3EYNA5NNA is a sophisticated adjustable frequency AC drive designed for robust performance in industrial environments. This unit is engineered to function at a voltage level of 480V AC and is configured for three-phase operation, handling an input current of up to 34 amps.

Protection is ensured by an enclosure that meets IP20 and NEMA Type 1 standards, providing adequate defense against dust and contact. A full numeric LCD interface displays operational metrics, granting users easy access to necessary information for monitoring and adjustments.

The drive employs IGBT technology for braking, contributing to efficient control of motor dynamics. Additionally, it incorporates an adjustable bus undervoltage trip feature to prevent potential issues related to voltage fluctuations. Thermal safety is monitored via a heat sink thermistor, which is supervised by a built-in microprocessor; this mechanism triggers an overtemperature trip if critical conditions arise.

Operational resilience is highlighted by the drive's logic control ride-thru capability, which lasts for 0.25 seconds when the drive is not actively running. Furthermore, in cases of brief power interruptions, the power ride-thru function maintains operation for 15 milliseconds under full load. Overall, the 20DD034A3EYNA5NNA is constructed to meet the rigorous demands of various industrial applications while offering precise control and safety features.
