20DD040A0NYNACNBN

The part number 20DD040A0NYNACNBN from Allen-Bradley represents an advanced adjustable frequency AC drive tailored for important industrial applications. Operating efficiently at a voltage rating of 480V AC, this drive supports a three-phase system and can manage up to 40 amps of normal-duty current, ensuring substantial power for various motor control needs.

The unit's design is enclosed in an IP20-rated housing that aligns with NEMA Type 1 standards, suitable for typical indoor environments. However, it comes with a blank cover for the human-machine interface, meaning it lacks interactive controls and displays features. Notably, this model does not include any documentation.

For added control and efficiency, the drive employs an IGBT braking system to enhance performance during operation. It also features an adjustable bus undervoltage trip, allowing settings to be tailored according to the operational parameters of the application.

Thermal management is a significant aspect of this unit, as it has a heat sink thermistor monitored by an internal microprocessor to trigger an over-temp trip when necessary, safeguarding against overheating. Furthermore, the drive offers a logic control ride-thru duration of 0.25 seconds when not running, which helps maintain control stability during brief interruptions. It also supports power ride-thru functionality for up to 15 milliseconds at full load, ensuring continuity during short voltage dips.
