20DR156A0EYNA1NNA

The 20DR156A0EYNA1NNA model is part of the PowerFlex 700S series, produced by Allen-Bradley under Rockwell Automation. Operating at a voltage rating of 650V DC, this adjustable frequency AC drive is engineered to accommodate demanding industrial applications. Its three-phase configuration supports significant electrical loads, with an input current capacity rated at 156 amps.

This drive features an IP20 rated enclosure compliant with NEMA Type 1 standards, ensuring it is suitable for indoor installations. The lack of a human-machine interface indicates a streamlined design, as it comes equipped with a blank cover. A quick start guide is available for initial setup and usage guidance.

Notably, the drive utilizes an IGBT braking mechanism, enhancing its dynamic response during operations. Safety features include an adjustable bus undervoltage trip, which can be customized for various operational thresholds. Furthermore, the integrated heat sink thermistor is monitored by a microprocessor to prevent overheating through an overtemperature trip.

To support system resilience, the drive allows for a logic control ride-thru time of 0.25 seconds when inactive. During full load conditions, a power ride-thru capability retains functionality for 15 milliseconds during transient power disturbances. This makes the 20DR156A0EYNA1NNA a robust choice for high-performance motor control applications.
