20DD034A0NYNARANL

The Allen-Bradley part number 20DD034A0NYNARANL represents a sophisticated adjustable frequency AC drive, optimized for reliable performance in various applications. This model works at a nominal voltage of 480 volts AC, accommodating three-phase power configurations. It can handle a maximum input current of 34 amps, providing robust support for demanding industrial tasks.

Housed in an enclosure with an IP20 rating that meets NEMA Type 1 standards, this unit is designed for indoor locations. The controller features a blank cover for its human-machine interface, indicating that user inputs are managed externally or through some other means.

The drive utilizes an IGBT braking system to manage motor operations effectively. For added safety and functionality, it incorporates an adjustable bus undervoltage trip feature, allowing users to customize its operational thresholds.

Thermal protection is provided by a heat sink thermistor that monitors temperatures through a microprocessor. This ensures that the drive remains within safe operating temperatures by triggering an automatic shutdown if necessary.

In terms of operational continuity, the drive supports logic control ride-thru for 0.25 seconds during periods when the drive is inactive. Additionally, under conditions of full load, it demonstrates a capability for power ride-thru, lasting up to 15 milliseconds, thereby enhancing the drive's reliability under varying load conditions.
