Featuring the part number 20DD500ACENNBNCNL, this Allen-Bradley adjustable frequency AC drive is part of the PowerFlex 700S series. Specifically engineered for three-phase systems, it operates at a voltage rating of 480V AC and allows for an impressive input current capacity of 500 amps. This robust functionality is essential for various industrial applications requiring significant power handling.
The drive is enclosed in an IP20-rated housing that complies with NEMA Type 1 standards, making it appropriate for typical indoor settings. It is equipped with a full numeric LCD for the human-machine interface, conveniently mounted on the door for ease of access. A quick start guide is included to facilitate installation and setup.
This unit does not integrate a braking system; however, it provides an adjustable bus undervoltage trip that amplifies safety during operational fluctuations. Furthermore, the heat sink thermistor is actively monitored by a microprocessor to prevent overheating issues during use. The logic control feature allows for ride-thru functionality, maintaining control for up to 0.25 seconds when the drive is not actively driving load. In addition, the model supports power ride-thru for 15 milliseconds at full load, contributing to stability during brief power interruptions.
