20DJ261N3NNNBCDCL

The 20DJ261N3NNNBCDCL adjustable frequency AC drive is produced by Allen-Bradley as part of the PowerFlex 700S series. It operates within a voltage range of 600V AC and supports three-phase input configurations. Capable of managing an input current of 261 amps at a maximum voltage of 650V, it is suitable for demanding industrial environments.

The design includes an open enclosure rated as IP00, which facilitates direct access to the unit's internal components. A full numeric LCD has been integrated for straightforward user interaction, allowing for efficient monitoring of operational parameters. However, documentation for this unit is not provided.

While this drive does not incorporate a braking mechanism, important safety features are included, such as an adjustable bus undervoltage trip that allows for customized protection settings against low voltage conditions.

Thermal protection is enhanced through a heat sink thermistor that is actively monitored by a microprocessor, which triggers an overtemperature trip when necessary to prevent overheating.

In terms of operational continuity, the drive is equipped with logic control ride-thru capabilities that last for 0.25 seconds while inactive. Furthermore, it supports power ride-thru for up to 15 milliseconds under full load, ensuring that performance is stable during brief power fluctuations.
