20DD052A5EYNANNNN

Designed as part of the Allen-Bradley PowerFlex 700S series, the 20DD052A5EYNANNNN adjustable frequency AC drive operates effectively at 480 volts in three-phase configurations. It accommodates an input current of up to 52 amps, making it suitable for various industrial motor control applications.

The device features an enclosure rated at IP20 according to NEMA Type 1 standards, providing protection suitable for clean indoor environments. It also has a programming-only LCD for user interaction, although no additional documentation is supplied with the unit.

For braking management, the drive utilizes IGBT technology, ensuring efficient control during operation. An adjustable bus undervoltage trip is integrated, allowing users to set voltage thresholds that meet specific operational standards. Additionally, an important thermal protection feature is provided through a heat sink thermistor that monitors temperatures via a microprocessor and activates an overtemperature trip as necessary.

The logic control system of the drive supports ride-thru capabilities, allowing for a 0.25-second buffer when the drive is not in operation. Moreover, the unit can sustain power ride-thru for 15 milliseconds at full load, which contributes to its reliability in conditions where brief power disturbances may occur. Overall, this model combines technology and functionality for improved performance in demanding applications.
