With the part number 20DC085A3EYNANCNL, the Allen-Bradley PowerFlex 700S series adjustable frequency AC drive is suited for demanding industrial applications. This unit operates on a three-phase system with a voltage rating of 400V AC. It can handle a current of 85 amps (normal duty), providing sufficient power for various motor functions. The device is enclosed in a NEMA Type 1, IP20-rated housing, which offers basic protection from environmental hazards.
A full numeric LCD serves as the human-machine interface, allowing for easy configuration and monitoring. The 20DC085A3EYNANCNL features an IGBT braking system for efficient operation and control.
Operational safety is enhanced through an adjustable bus undervoltage trip feature. The heat sink thermistor is equipped with overtemp trip monitoring managed by a microprocessor, ensuring the drive operates within safe temperature limits. The logic control ride-thru time is 0.25 seconds when the drive is not actively running, while it maintains power ride-thru capabilities for up to 15 milliseconds at full load, which is critical for continuous operation during brief power disturbances.
