20DD261A3EYNBCNBN

The 20DD261A3EYNBCNBN from Allen-Bradley is designed as an adjustable frequency AC drive with a capability to operate at 480V AC for three-phase applications. This unit is rated for an input current of 261 amps, meeting the requirements for high-demand industrial use. Its construction adheres to NEMA Type 1 standards, encapsulated in an IP20 enclosure that safeguards against dust and particulate ingress.

Users benefit from a full numeric LCD interface, which facilitates straightforward operation and monitoring. The model includes a quick start guide for simplified setup. Key functional features incorporate an IGBT braking system, enhancing performance during operation. Furthermore, the adjustable bus undervoltage trip ensures user-defined thresholds for optimal safety during performance.

A heat sink thermistor is integrated and monitored by a microprocessor to provide advanced thermal protection. This setup allows for automatic responses to potential heating issues, ensuring ongoing efficient operation. The drive supports logic control ride-thru capability for 0.25 seconds when inactive, allowing brief fluctuation handling without disruption. Additionally, the power ride-thru functionality extends for up to 15 milliseconds during full load conditions, a critical specification for maintaining system stability under transient events.
