The Allen-Bradley part number 20DJ46020NNNB1CSK is categorized as an adjustable frequency AC drive. This device is built to function with a voltage rating of 650 volts DC. It accommodates a substantial normal-duty current of 460 amps, making it suitable for high-demand applications requiring effective motor control.
The drive is designed with an open-style enclosure, classified as IP00, which provides some protection against dust and moisture. Notably, this model utilizes a blank cover for its human-machine interface, indicating that external controls may be implemented. Documentation for the device is not included, and there is no integrated braking functionality.
For safety and performance, the unit offers an adjustable bus undervoltage trip feature, allowing for customization according to specific operational parameters. To manage thermal conditions, the drive is equipped with a heat sink thermistor actively monitored by a microprocessor, triggering an overtemperature trip if necessary.
The logic control ride-thru capability lasts 0.25 seconds during periods of inactivity. Furthermore, it can sustain power ride-thru for 15 milliseconds under full load to maintain control during brief power disruptions. The 20DJ46020NNNB1CSK effectively combines operational reliability and efficiency for various industrial settings.
