20DD261A0EYNNNCNK

The 20DD261A0EYNNNCNK adjustable frequency AC drive from Allen-Bradley is developed for handling significant operational demands. Operating at a voltage rating of 480 volts AC, this model is specifically configured for use in three-phase systems and capable of managing an input current of 261 amps.

Constructed with an IP20 enclosure that meets NEMA Type 1 standards, this device is built for standard indoor usage while providing moderate protection. The drive’s interface features a blank cover, and a quick start guide is included to facilitate straightforward set-up.

An IGBT braking system is utilized, enhancing the unit's operational efficiency. For safe operation, the drive incorporates an adjustable bus undervoltage trip feature, helping to prevent system faults. To maintain optimal temperatures, the system includes a heat sink thermistor that is actively monitored by a microprocessor, which can consequently trigger an overtemperature trip if necessary.

This drive is also capable of logic control ride-thru for a duration of 0.25 seconds when the unit is inactive. Furthermore, it maintains power for up to 15 milliseconds while under full load, ensuring reliable continuation of operations during brief power outages. The 20DD261A0EYNNNCNK presents a robust solution for applications that demand versatile motor control in industrial settings.
