20DD261N3EYNBDNNN

The part number 20DD261N3EYNBDNNN represents an adjustable frequency AC drive designed specifically for three-phase applications at 480 volts AC. Manufactured by Allen-Bradley, this device can accommodate a significant input current of 261 amps. It is delivered within an IP20 enclosure that meets NEMA Type 1 standards, making it suitable for typical indoor environments.

The drive is designed without a human-machine interface, featuring a blank cover. This simplification is useful in applications where an external control interface is either unnecessary or managed through different means. A quick start guide accompanies the drive for an efficient installation process.

It utilizes an IGBT braking system for effective control during operational transitions. The device incorporates an adjustable bus undervoltage trip to enhance safety during use. Keeping track of thermal conditions is made possible by the heat sink thermistor, which is continuously monitored by a microprocessor to prevent overheating.

For operational stability, the drive maintains logic control ride-thru capabilities for up to 0.25 seconds when it is not actively running. Additionally, in the face of transient conditions, it supports power ride-thru functionality for as long as 15 milliseconds at full load, ensuring continuity in operations under varying electrical supply conditions. This blend of features positions the 20DD261N3EYNBDNNN as a reliable component within the PowerFlex 700S series.
