20DJ261N0ENNBNASE

Model 20DJ261N0ENNBNASE from Allen-Bradley is an adjustable frequency AC drive optimized for demanding industrial operations. This three-phase drive functions at a voltage of 600V AC and can handle a maximum input current of 261 amps. Its construction supports high performance across varying load conditions.

The enclosure is classified as open/IP00, denoting that it lacks a protective cover. This design permits easy access but necessitates placement in clean environments. The human-machine interface is absent, simplifying the layout, in line with applications where other controls may be integrated.

Included with the unit is a quick start guide, easing initial setup and commissioning. The drive integrates an adjustable bus undervoltage trip, enhancing operational safety. It does not include a braking mechanism, which might be a consideration for specific applications.

To ensure thermal safety, the heat sink thermistor is continuously monitored by a microprocessor, providing alerts for possible overheating conditions. The unit features logic control that enables ride-thru capabilities of 0.25 seconds when the drive is inactive. Moreover, during full load scenarios, the power ride-thru can sustain operation for 15 milliseconds, maintaining stability during momentary power fluctuations. This drive is suitable for a range of tasks requiring reliable performance under high demands.
