The Allen Bradley 20AD027C5AYNASNN is a variable-frequency AC drive optimized for three-phase power applications with an operating voltage of 480 V AC. Designed to handle a continuous duty current of 27 A, it provides a robust 20 horsepower at normal conditions. For heavy-duty usage, it can manage 15 horsepower, making it versatile for demanding operational requirements.

This unit is built for either wall or machine mounting, offering flexibility in installation configurations. Its enclosure, rated IP66/NEMA Type 4X/12, ensures protection against dust and water, and is capable of withstanding wash-down procedures in indoor environments. The built-in LCD allows for effective metering and configuration, but there are no keypad controls since it utilizes a programming-only module.

Additionally, the drive comes equipped with a brake IGBT, which facilitates dynamic braking. While the drive-mounted resistor is not included, it can be added in the field as necessary. In terms of communications, the system features an RS-485 DF-1 serial link, enhancing connectivity options.

The control method implemented is scalar V/Hz (volts-per-Hertz), providing straightforward control over motor speed. Notably, this drive operates without requiring encoder or resolver feedback, functioning in an open-loop configuration. This specification simplifies installation and integration into various systems, making the 20AD027C5AYNASNN a practical choice for multiple applications.
