20DJ300N0NNNBCASE

The 20DJ300N0NNNBCASE, produced by Allen Bradley under Rockwell Automation, functions as an adjustable frequency AC drive with a primary operating voltage of 600V AC. This unit is designed for three-phase applications and is capable of managing up to 300 amps at an input voltage of 650V.

This AC drive is constructed without a typical enclosure, rated as open/IP00, implying its unsuitability for environments that require protection against dust and moisture. There is no human interface integrated, featuring instead a blank cover, which simplifies its external design. Furthermore, the unit does not come with accompanying documentation.

It does not have an integrated braking system. However, safety features include an adjustable configuration for the bus undervoltage trip, providing the operator the ability to calibrate according to specific needs. The thermal management system relies on a heat sink thermistor which is meticulously monitored by the internal microprocessor to prevent any overheating issues.

The system supports logic control ride-thru capability for 0.25 seconds while not actively engaged, allowing for brief interruptions without immediate impact on performance. Additionally, it maintains power ride-thru for up to 15 milliseconds at full load, ensuring operational stability during short power fluctuations.
