20DD077A0EYNA1CEK

The Allen-Bradley part number 20DD077A0EYNA1CEK is an adjustable-frequency AC drive within the PowerFlex 700S series. It is optimized for three-phase power applications and operates efficiently at 480V AC. This model is engineered to handle a normal-duty current of up to 77 amps, enabling its usage in various industrial settings requiring substantial control over motor functions.

The drive is housed in an enclosure that meets IP20 and NEMA Type 1 specifications and is designed to offer basic protection against dust and contacts. The interface option is only a non-functional blank plate.

The drive employs IGBT technology for its braking functions, enhancing performance and responsiveness when controlling motor speed and torque. Additionally, it features an adjustable bus undervoltage trip, which allows users to set specific thresholds for optimal operation. Integrated into the design is a heat sink thermistor, which monitors thermal conditions, triggered by a microprocessor to prevent overheating incidents.

In moments of brief interruptions, the logic control offers a ride-thru capacity of 0.25 seconds while the drive is not engaged. At full load, the power ride-thru duration is effective for up to 15 milliseconds, maintaining operational stability during temporary power disturbances. The combination of these specifications ensures that the 20DD077A0EYNA1CEK drive delivers reliable performance across its intended applications.
