20DJ248A0ENNA1CSK

Designed for reliable operation, the Allen-Bradley 20DJ248A0ENNA1CSK is an adjustable frequency AC drive suitable for three-phase electrical configurations. With a voltage rating of 600V AC, this unit can handle a significant input current of 248 amps at a maximum of 650V. Housing this drive is an IP20-rated enclosure, compliant with NEMA Type 1 standards, which provides sufficient protection for indoor applications.

The drive features a blank cover for its human-machine interface, ensuring a streamlined design without visible controls. A quick start guide is included to facilitate installation and initial setup. Unlike some drive models, this unit does not feature an integrated braking system.

For operational safety, the drive incorporates an adjustable bus undervoltage trip, allowing for extended flexibility based on specific application requirements. Monitoring thermal levels is effectively managed by a heat sink thermistor, continuously watched over by an integrated microprocessor. This arrangement triggers an overtemperature trip if limits are exceeded, preventing potential damage.

The logic control capabilities of the drive enable a ride-thru duration of up to 0.25 seconds during inactive states. Furthermore, it maintains power for 15 milliseconds at full load during momentary power disturbances, ensuring robust performance in critical industrial environments.
