20BD077A0AYNAED0

The Allen Bradley 20BD077A0AYNAED0 is an AC drive belonging to the PowerFlex 700 lineup, characterized by impressive specifications designed for enhanced functionality in industrial applications. This drive operates efficiently with a continuous output current of 77A at 650V DC under normal duty, making it suitable for various tasks requiring reliable performance. For short-term heavy-duty applications, the drive supports output currents of up to 98A for one minute and surges to 130A for three seconds.

Rated for use up to 1000 m (3300 ft), the drive maintains consistent operations without derating at this altitude. Its design incorporates NEMA Type 1 protection, ensuring reliable function in environments up to 50 °C as per its surrounding air temperature specifications. Additionally, this drive allows for a wide range of relative humidity from 5% to 95% without concern for condensation, making it highly flexible for use in different settings.

The unit has a sound level of 59 dB when the fan operates at a velocity of 190 CFM, maintaining manageable noise levels during operations. An input current rating of 84.5A at 650V DC is suitable for driving a 60 Hp load under normal duty while ensuring effective control. This drive incorporates various carrier frequency options—2, 4, 8, and 10 kHz—with its drive rating based on 4 kHz, thus enabling customizable performance based on application needs.

Furthermore, the encoder quadrature is specified at 90 degrees with a ±27 degree tolerance at 25 °C, allowing for precise motor control. Notably, the AC input overvoltage trip is set at 570V AC when connected to a 480V supply, enhancing safety through effective voltage management. Overall, the 20BD077A0AYNAED0 provides robust capabilities, suitable for a wide range of demanding industrial environments.
