The 20DD125A3EYNANAUE adjustable frequency AC drive manufactured by Allen-Bradley is built to operate at 480 volts AC in a three-phase setup. It supports a maximum input current rating of 125 amps, offering significant power handling capabilities. The drive is housed in an enclosure rated IP20, aligning with NEMA Type 1 standards, suitable for typical industrial environments.
A full numeric LCD serves as the human interface, allowing easy access to settings and operational parameters. A Quick Start Guide is provided to facilitate initial setup. The unit employs IGBT technology for braking, enhancing performance and safety during operation. Furthermore, it features an adjustable bus undervoltage trip function, which can be tailored to meet specific operational settings.
To monitor heat levels effectively, the heat sink thermistor is actively managed by a microprocessor, triggering overtemp trips as needed to maintain optimal performance. In addition, while the drive is inactive, it allows for a logic control ride-thru of 0.25 seconds, ensuring stability during brief power interruptions. It provides power ride-thru capability for 15 milliseconds at full load, enabling the drive to maintain functionality even in the event of a temporary loss of input power.
