The 20DJ300N5NNNBCNNN is part of the Allen-Bradley PowerFlex 700S series, designed for effective motor control in demanding applications. It operates on a 650V DC input voltage and is configured for accommodating up to 300 amps of normal-duty current.
This adjustable frequency drive is housed in an open-style enclosure classified as IP00, allowing it to function in controlled conditions without additional dust or moisture protection. The human interface machine is a programmer-only LCD display, which facilitates setup and operation without extensive documentation.
Notably, this drive does not include a braking feature, which is essential for many dynamic applications. It supports an adjustable bus undervoltage trip to prevent operational issues due to low voltage conditions. Additionally, a heat sink thermistor is actively monitored by a microprocessor to avoid overheating, ensuring reliable operation during varied load conditions.
This drive maintains logic control ride-thru for a brief period of 0.25 seconds when not operational, allowing for brief interruptions in power without losing settings. Furthermore, it can sustain power ride-thru for up to 15 milliseconds at full load, adding to its versatility in real-world application scenarios.
