20DJ125A3NNNA1NNB

The 20DJ125A3NNNA1NNB adjustable frequency AC drive is manufactured by Allen-Bradley, part of Rockwell Automation's PowerFlex 700S series. This drive is rated for operation at voltages up to 600V AC and is designed for three-phase electrical systems, ensuring stable performance in high-demand environments. It accommodates a substantial input capacity, handling up to 125 amps, making it suitable for various industrial applications.

Featuring an IP20-rated enclosure that meets NEMA Type 1 standards, the 20DJ125A3NNNA1NNB is safeguarded against common environmental factors. For effective monitoring and adjustments, it is equipped with a full numeric LCD, providing users with clear operational data.

The drive lacks an integrated braking system, however, it includes an adjustable bus undervoltage trip feature to help prevent operational interruptions. Thermal management is supported by a heat sink thermistor, which is monitored by a microprocessor for over-temperature protection. Cooling is a priority, as the device can maintain operational integrity even under demanding conditions.

This model incorporates logic control ride-thru capability, sustaining operation for 0.25 seconds while the drive is not running. Additionally, the system can manage brief power loss scenarios, providing 15 milliseconds of ride-thru at full load to help maintain performance during electrical fluctuations. The 20DJ125A3NNNA1NNB is engineered for reliability and efficiency in critical industrial processes.
