20DJ460N0NNNBCASE

The 20DJ460N0NNNBCASE is a robust adjustable frequency AC drive offered by Allen-Bradley, within the PowerFlex 700S series, designed specifically for high-voltage applications. It operates at a noteworthy voltage of 650V DC. The unit delivers substantial performance levels with a normal-duty current capability of 460 amps.

Constructed with an open-style design and rated at IP00, this drive is suitable for environments where it can be adequately protected from external contaminants. Notably, it has no human-machine interface due to its blank cover, which simplifies its installation in existing setups.

There are no braking provisions within this drive, making it essential to consider additional solutions for applications needing braking. The drive also incorporates an adjustable bus undervoltage trip that permits customization to address specific operational safety needs.

Additionally, the thermistor mounted on the heat sink is vigilantly supervised by a microprocessor, ensuring temperature levels are kept in check. If the temperatures reach critical levels, the overtemperature trip feature activates to protect the unit from damage.

In terms of maintaining operational stability, this unit provides logic control ride-thru functionality for 0.25 seconds when the drive is not actively running, along with a power ride-thru feature that guarantees continued performance for a brief duration of 15 milliseconds at full load. This capability is crucial in preventing disruptions in critical applications, ensuring that system operations are maintained even during transient fluctuations.
