20DJ460N0NNNBCANE

The 20DJ460N0NNNBCANE is an adjustable frequency AC drive manufactured by Allen-Bradley under the Rockwell Automation banner. This drive operates at 650 volts DC input voltage. It is capable of handling an impressive normal-duty current of up to 460 amps, which makes it suitable for demanding applications requiring robust power management.

With an open enclosure rated as IP00, this model lacks protection from dust and moisture resistance features, making it important to consider installation environments. A blank cover indicates the lack of a conventional human-machine interface on this unit, which may require external controls for interaction. Notably, users will find that there is no accompanying documentation provided with this unit.

The absence of a braking system in this configuration is significant for considerations in applications requiring rapid motor stops. Key safety features include an adjustable bus undervoltage trip and a heat sink thermistor that is monitored for overtemperature conditions by the integrated microprocessor. This safety mechanism proactively prevents overheating during normal operation.

In terms of operational resilience, the unit supports a logic control ride-thru capability, allowing for a transition period of 0.25 seconds when idle. Additionally, the 20DJ460N0NNNBCANE can handle power ride-thru for up to 15 milliseconds under full load conditions, ensuring stability in the event of brief power interruptions.
