The 20DD248A3NNNANGNE is part of the Allen-Bradley PowerFlex 700S series, designed specifically as an adjustable-frequency AC drive. This model can function at an input voltage rating of 480V AC, making it suitable for various industrial applications requiring substantial power. It features a maximum normal-duty current rating of 248 amps, ideal for demanding operational requirements.
Housed in an IP20-rated enclosure that complies with NEMA Type 1 standards, the drive is engineered for indoor use. It is equipped with a full numeric LCD that offers ease of access for user controls and monitoring.
Notably, this drive does not come with a built-in brake mechanism. However, it includes safety features such as an adjustable bus undervoltage trip that can be customized to meet specific operational parameters. Additionally, the heat sink thermistor is actively monitored by a microprocessor to avoid overheating, enhancing the reliability of the system in extended use.
Regarding capability during electrical disturbances, the drive offers a logic control ride-thru time of 0.25 seconds when the unit is idle, ensuring stability during brief outages. For conditions of brief power loss, it is capable of sustaining a power ride-thru for 15 milliseconds at full load, which is beneficial for maintaining operational consistency in critical environments.
