The 20DJ38520ENNBNNNN part number is part of the PowerFlex 700S series from Allen-Bradley. This unit serves as an adjustable frequency AC drive, primarily intended for advanced industrial applications. It operates capable of handling a maximum input voltage of 650 volts DC, delivering 385 amps of normal-duty current. Installed within an IP20 enclosure that complies with NEMA Type 1 standards, the drive allows for versatility in indoor installation.
Notably, this model lacks a human-machine interface since it comes equipped with a blank cover. For controlling conditions, it features an adjustable bus undervoltage trip to help protect working circuits. The unit employs a heat sink thermistor, which is continuously monitored by a microprocessor, ensuring any potential overheating issues are detected early by triggering an over-temperature trip.
In terms of operational reliability, the drive can maintain a logic control ride-thru time of 0.25 seconds when it is not actively running, preserving stability during brief power interruptions. Furthermore, it is equipped to sustain power ride-thru of up to 15 milliseconds while at full load, enhancing its usability and safety in demanding environments.
