20DC085A0EYNANANL

The part number 20DC085A0EYNANANL is an adjustable frequency AC drive manufactured by Allen-Bradley, a division of Rockwell Automation. This device operates on a three-phase system with a nominal voltage of 400V AC, making it versatile for large industrial applications. The drive has a significant normal duty current capacity of 85 amps and is built within an IP20 (NEMA Type 1) enclosure that provides protection against dust and solid objects in indoor environments.

A notable aspect of this drive is the absence of a human-machine interface, signifying a straightforward operational design focused on efficiency.

For safety and performance, it integrates an IGBT braking system and features an adjustable bus undervoltage trip, allowing for tailored protection against voltage drops. The heat sink thermistor provides continuous monitoring of thermal conditions and is controlled by a microprocessor to prevent overheating through an automatic shut-off feature in critical situations.

In terms of operational resilience, the device supports a logic control ride-thru time of 0.25 seconds when not actively running, which aids in maintaining system stability during power fluctuations. Furthermore, the unit is equipped with a power ride-thru capability allowing it to sustain operational integrity for up to 15 milliseconds under full load scenarios. This combination of features ensures the drive remains reliable and functional in demanding industrial settings.
