20DD125A3EYNA1NNA

The Allen-Bradley 20DD125A3EYNA1NNA adjustable frequency AC drive supports three-phase operations at a voltage of 480V AC, making it suitable for extensive industrial applications. Capable of managing an input current of up to 125 amps, this drive provides considerable flexibility for various motor control tasks.

Its IP20-rated enclosure, corresponding to NEMA Type 1 standards, ensures sufficient protection against dust and incidental contact, which is vital for maintaining operational reliability in typical settings.

The unit is equipped with a full numeric LCD human interface, facilitating ease of monitoring and adjustments. The absence of documentation implies a well-integrated system that meets established criteria for installation and operation.

A significant feature of this drive is the IGBT braking system that enhances performance during quick stops and starts. Additionally, it incorporates an adjustable bus undervoltage trip to safeguard against fluctuating voltage levels, while a heat sink thermistor is monitored by a microprocessor, ensuring the unit remains within safe temperature limits.

The 20DD125A3EYNA1NNA drive further supports a logic control ride-thru for 0.25 seconds in non-active periods, and can endure 15 milliseconds of power ride-thru at full load. These protective features contribute to the drive's reliability and efficiency in challenging operational environments.
