The 20DD040A3NYNANNNA is part of the PowerFlex 700S series from Allen-Bradley, a division of Rockwell Automation. This adjustable-frequency AC drive is engineered for effective operation in three-phase systems, operating at 480V AC. It is rated to handle a maximum normal-duty current of 40 amps, making it suitable for a variety of industrial applications.
Designed for indoor use, the drive features an IP20-rated enclosure that meets NEMA Type 1 specifications, offering basic protection from dust and contact. Users can interact with the system through a full numeric LCD interface, although it does not come with additional documentation, which may require prior knowledge for setup and operation.
This device employs IGBT technology for braking, ensuring efficient control during operational changes. The adjustable bus undervoltage trip helps users configure settings to specific applications, enhancing system reliability. A microprocessor actively monitors the heat sink thermistor, providing thermal protection by triggering an overtemperature trip when necessary.
For continuity in operation, the drive supports logic control ride-thru for 0.25 seconds when the drive is idle. In the event of temporary power loss, it can sustain functionality for 15 milliseconds under full load conditions, contributing to its overall robustness and reliability in demanding scenarios.
