The 20DD500N0NNNBRANE, part of the PowerFlex 700S series from Allen-Bradley, functions as an adjustable frequency AC drive suitable for high-demand applications. This model operates with a voltage rating of 480V AC and is configured for three-phase power, allowing it to manage an input current of up to 500 amps.
Designed without a protective enclosure, this device is classified as open and adheres to IP00 standards, making it ideal for environments where external shielding is not a priority. The unit lacks a typical human interface, featuring a blank cover instead. Documentation is not included with this model, emphasizing its streamlined design.
A significant aspect of this drive is its adjustable bus undervoltage trip, which enhances safety by allowing users to set operational parameters according to their requirements. There is no braking mechanism incorporated in this drive; however, a heat sink thermistor is actively monitored by a microprocessor to mitigate risks of overheating and ensure safe operation.
During periods of downtime when the drive is not in use, it offers a logic control ride-thru capability of 0.25 seconds, ensuring stable operation during temporary load disturbances. Furthermore, the unit can maintain power ride-thru for up to 15 milliseconds while fully loaded, contributing to its reliability in various demanding industrial tasks.
