20DD052A0QYNANNNN

The part number 20DD052A0QYNANNNN represents an adjustable frequency AC drive manufactured by Allen-Bradley within the PowerFlex 700S series. This drive functions effectively with an input voltage of 480 volts AC and operates in a three-phase arrangement. It is capable of handling an input current of 52 amps, making it suitable for a variety of motor control applications.

Housed in an IP20 enclosure that meets the NEMA Type 1 specifications, the drive is protected against certain environmental factors suitable for industrial applications. The human-machine interface features a blank cover, which indicates that user controls are handled externally. Notably, the unit does not come with documentation.

For operational safety and efficiency, this drive includes an IGBT braking system to ensure effective control over motor operations. Furthermore, it has an adjustable bus undervoltage trip, allowing users to set specific thresholds to suit their needs. The drive’s heat sink thermistor is monitored by a microprocessor that can initiate an overtemperature trip if necessary, protecting the unit from overheating.

During operation, the drive can maintain logic control ride-thru for approximately 0.25 seconds while it is not running, ensuring system stability. The power ride-thru feature allows continuous operation for 15 milliseconds at full load, helping to manage transient power interruptions.
