20DD261A3ENNNEANE

The Allen-Bradley 20DD261A3ENNNEANE is a manual-regulated adjustable frequency AC drive, designed for diverse industrial environments. This unit is capable of operating on a voltage of 480V AC, making it ideal for three-phase power applications. It accommodates an input current of 261 amps, providing sufficient power for demanding tasks. Constructed with an IP20 enclosure, which adheres to NEMA Type 1 standards, this device provides necessary protection in standard indoor environments.

The user interface consists of a full numeric LCD, allowing for convenient operation and monitoring. Although this model does not come with a brake feature, it compensates with an adjustable bus undervoltage trip, providing flexibility in settings tailored to specific operational needs. Thermal management is achieved through a heat sink thermistor that is actively monitored by a microprocessor, allowing safe operation by triggering an overtemperature trip when necessary.

In terms of reliability, the drive is equipped with a logic control ride-thru capability lasting 0.25 seconds when the drive is inactive, ensuring that temporary outages do not disrupt functionality. It also supports a brief power ride-thru duration of 15 milliseconds at full load, which helps maintain operation during minor power fluctuations. This comprehensive set of features makes the 20DD261A3ENNNEANE a competent option for various applications requiring precise motor control.
