20DD040A3EYNAENNN

The Allen-Bradley 20DD040A3EYNAENNN is categorized as an adjustable frequency AC drive, specifically designed for demanding industrial environments. Operating at 480 volts AC, this unit supports three-phase voltage configurations seamlessly. The drive is rated to handle normal-duty currents of up to 40 amps, making it suitable for a wide variety of applications requiring reliable speed and torque control.

The drive, housed in an IP20-rated enclosure that meets NEMA Type 1 standards, has adequate protection against dust and moisture in moderate indoor environments. A full numeric LCD serves as the human-machine interface, allowing users to easily monitor and control the unit’s performance.

The 20DD040A3EYNAENNN employs IGBT technology for its braking system, ensuring efficient operation across various working conditions. Safety is enhanced with an adjustable bus undervoltage trip, allowing customization based on operational requirements. For thermal regulation, the heat sink thermistor is actively monitored by a microprocessor, which triggers an overtemperature trip in case of excessive heat buildup.

In terms of operational reliability, the drive features a logic control ride-thru capability for 0.25 seconds when not in use, ensuring seamless operation during brief interruptions. Furthermore, it supports power ride-thru functionality for up to 15 milliseconds at full load, safeguarding against temporary power disturbances. Overall, this drive is engineered to meet the challenges of modern industrial applications.
