20DC205A3ENNA1NNA

The part number 20DC205A3ENNA1NNA, produced by Allen-Bradley and part of the PowerFlex 700S line, is constructed to deliver adjustable frequency control in three-phase applications. This drive operates with an input voltage of 400 volts AC and is capable of handling a substantial 205 amps normal-duty current. This kind of capacity makes it suitable for high-demand industrial scenarios.

The unit is housed in an enclosure rated at IP20, compliant with NEMA Type 1 standards. This rating offers adequate protection against contact with objects and dust, suitable for controlled environments. Interfacing with the drive is simplified through the inclusion of a full numeric LCD, which delivers data monitoring and operational commands effectively.

Notably, this drive does not include a braking system, focusing instead on providing reliable motor control. It features an adjustable bus undervoltage trip to safeguard the system against low voltage scenarios. Additionally, a thermistor is implemented in the heat sink monitoring system, assessed by a microprocessor to trigger an overtemperature trip as required.

The logic control ride-thru functionality allows the drive to maintain operation for up to 0.25 seconds while not actively running. Furthermore, it has a power ride-thru capability of 15 milliseconds during full load, ensuring operational stability under transient power conditions. Overall, the 20DC205A3ENNA1NNA is optimized for reliability in motor-driven environments.
