With a part number of 20DD385BCENNBNANE, the Allen-Bradley adjustable frequency AC drive is tailored for operation in three-phase systems at a voltage of 480V AC. It accommodates a normal-duty current rating of up to 385 amps, making it suitable for a wide range of industrial applications requiring reliable motor control. The drive is housed in an enclosure that meets the IP20 and NEMA Type 1 standards and offers a conformal coat to protect it from dust and moisture.
This model features a blank cover rather than a traditional interface. Safety features include an adjustable bus undervoltage trip, allowing users to set specific parameters for protection against voltage drops. The heat sink thermistor is closely monitored by a microprocessor, ensuring that the unit remains within safe temperature limits and activating an overtemperature trip if necessary.
During periods of inactivity, the drive can sustain a logic control ride-thru duration of 0.25 seconds. It also supports a power ride-thru of 15 milliseconds at full load, ensuring stability in the event of brief power disruptions. This drive's configuration and protection features make it a robust solution for demanding operational environments.
