20DD156A3NNNANANE

The Allen-Bradley 20DD156A3NNNANANE is an adjustable-frequency AC drive specifically built for demanding industrial environments. Operating at 480V AC, this unit is tailored for three-phase interactions. Its impressive current capacity of 156 amps enables efficient handling of substantial power loads.

This drive is housed in an IP20-rated enclosure that conforms to NEMA Type 1 standards, providing adequate protection against dust while being designed for indoor applications. The integrated human-machine interface features a full numeric LCD, offering a straightforward method for monitoring and adjusting operational parameters. Notably, this drive does not have an inbuilt braking system.

For safety and reliability, the device is equipped with an adjustable bus undervoltage trip feature, allowing customization to meet specific operational thresholds. To prevent overheating, a heat sink thermistor monitors the temperature and is overseen by a microprocessor that triggers an overtemperature protection functionality when necessary.

Regarding operational continuity, the unit provides a logic control ride-thru capacity of 0.25 seconds during which the drive is non-operational. Additionally, it is capable of sustaining a power ride-thru lasting 15 milliseconds under full load, ensuring consistent performance even during brief electrical interruptions. The 20DD156A3NNNANANE drive exemplifies robustness and reliability for various applications demanding precise motor control.
