The 20DR248A3NNNA1CNK, part of the Allen-Bradley PowerFlex 700S series, is designed as an adjustable frequency AC drive specifically for 3-phase systems. This unit accommodates an operational voltage of 650 volts DC, providing substantial power handling with a maximum input current of 248 amps.

Built with an IP20-rated enclosure under NEMA Type 1 specifications, this drive ensures basic protection from environmental factors. Users interact with the system through a full numeric LCD display, which facilitates the monitoring and adjustment of operating conditions. No supplementary documentation comes with the unit.

This model does not incorporate an integrated braking system. However, it includes an adjustable bus undervoltage trip feature that offers an added layer of safety. The heat sink's thermistor is monitored by a microprocessor to prevent overheating, providing reliable performance. The drive supports logic control allowing for a ride-thru time of 0.25 seconds while idle, and maintains a power ride-thru capability for 15 milliseconds when fully loaded. This combination of features demonstrates its suitability for various industrial applications.
