Representing the PowerFlex 700S series, the 20DC085A3NNNA1NBA adjustable frequency AC drive is engineered to operate at 400 volts AC. This model is configured for three-phase power systems and supports a high current capability of 85 amps (normal-duty). The design ensures reliable performance in a variety of industrial applications.

This drive is enclosed in an IP20-rated chassis, compliant with NEMA Type 1 standards, which protects the internal components from dust and contact with larger objects while allowing for indoor use. Interactivity with the drive is facilitated through a full numeric LCD, allowing for straightforward monitoring. However, no accompanying documentation is provided.

The 20DC085A3NNNA1NBA does not incorporate a braking function. To enhance safety, the system includes an adjustable bus undervoltage trip feature, allowing users to set specific voltage levels to prevent operations under unsuitable conditions. Continuous operation is also safeguarded by a heat sink thermistor, which is monitored by the internal microprocessor to prevent overheating.

For added reliability, this model supports logic control ride-thru functionality lasting 0.25 seconds when not in operation. Additionally, the power ride-thru capability can maintain functionality for up to 15 milliseconds at full load, ensuring minimal disruption in case of brief power fluctuations.
