20DD077A3EYNA6CNK

The 20DD077A3EYNA6CNK, produced by Allen-Bradley under the PowerFlex 700S series, functions as an adjustable frequency AC drive crucial for motor control applications. This unit operates at a voltage rating of 480V AC and is designed specifically for three-phase voltage configurations. Supporting a strong normal-duty current capacity of 77 amps, it is engineered to handle a wide range of industrial tasks.

The drive features an enclosure that meets NEMA Type 1 standards and has an IP20 rating, making it suitable for use in controlled indoor environments. It is fitted with a full numeric LCD for user interaction, allowing operators to easily monitor and modify settings.

The unit employs IGBT braking technology to ensure efficient motor operation, while an adjustable bus undervoltage trip setting enhances safety by preventing faults caused by unexpected voltage drops. Temperature management is seamlessly integrated with a heat sink thermistor, which is continuously monitored by a microprocessor to detect overtemperature conditions.

Additionally, the drive supports logic control ride-thru for 0.25 seconds when not actively engaged, ensuring system stability during brief interruptions. The power ride-thru feature extends for 15 milliseconds under full load, further enhancing its reliability in fluctuating conditions. The Allen-Bradley 20DD077A3EYNA6CNK drive is a reliable solution for various industrial automation needs.
