20DC140A0ENNANANE

The 20DC140A0ENNANANE adjustable frequency AC drive, a product of Allen-Bradley within the PowerFlex 700S series, is engineered for efficient motor control. This model operates at a nominal voltage of 400V AC and is designed for three-phase electrical systems. It can support a normal duty current of 140 amps, ensuring it is suitable for substantial industrial applications.

Constructed within an IP20 enclosure, compliant with NEMA Type 1 standards, this drive is designed for use in indoor environments where it faces minimal exposure to dust and moisture. The design opts for a blank cover instead of a human interface machine, promoting a streamlined unit without display features.

This model does not incorporate a braking system, allowing for straightforward operational implementation. Importantly, it features an adjustable bus undervoltage trip to enhance safety during condition fluctuations. The heat sink thermistor incorporates a microprocessor that monitors temperature, triggering an overtemperature trip when necessary to prevent potential failures.

For operational resilience, the drive includes a logic control ride-thru capacity of 0.25 seconds while not actively running. In addition, it can accommodate a power ride-thru situation lasting up to 15 milliseconds under full load conditions, helping to maintain operations during transient power disturbances.
