20DD8P0A0EYNANNNA

The model 20DD8P0A0EYNANNNA by Allen-Bradley is part of the PowerFlex 700S series. It functions as an adjustable-frequency AC drive suitable for integrating into three-phase electrical systems. This drive's operating voltage is 480V AC, and it can efficiently handle a normal-duty current of up to 8 amps.

With an enclosure rating of IP20 and compliance with NEMA Type 1 standards, this unit is intended for indoor applications where basic protection is adequate. Notably, the human-machine interface is represented by a blank cover, indicating simplicity in design without external controls.

This drive does not include a braking feature but instead incorporates an IGBT for torque control. Enhanced safety is achieved through the adjustable bus undervoltage trip, which allows users to customize protection based on specific application needs. Additionally, the heat sink thermistor, which is actively monitored by a microprocessor, prevents overheating through an automatic trip when critical temperatures are reached.

For reliability, the drive ensures a logic control ride-thru capability of 0.25 seconds while not actively running. Moreover, during full load conditions, it can maintain power ride-thru for 15 milliseconds, which is essential for operational stability during brief power interruptions. Overall, the 20DD8P0A0EYNANNNA drive is engineered to meet the performance demands of diverse applications while ensuring effective motor control.
