20BD077A0NYNACC1

The 20BD077A0NYNACC1 is an AC drive developed by Allen Bradley as part of the PowerFlex 700 series. It is constructed to function efficiently at an input voltage of 480V AC in a three-phase configuration, specifically designed for 60 Hz applications. The drive supports various operational requirements through the inclusion of a Brake IGBT for enhanced braking effects while lacking an internal brake resistor. Feedback during operation can be obtained through its standard encoder, providing valuable performance data.

Electrical noise is minimized by employing both an EMC filter and a common mode choke, ensuring the system operates reliably in industrial settings. This unit utilizes a PWM frequency of 4 kHz when operating at 650V DC, which contributes to efficient motor control. Additional resilience is found in the drive's capability to withstand shocks up to 15 G for 11 milliseconds, with a permissible vibration of 0.152 mm displacement under peak conditions of 1 G.

Feedback options include analog outputs rated at 200%, allowing for enhanced monitoring capabilities. The mains voltage rating for this model is set at 480V, with a fuse current rating of 150A at 650V DC, ensuring robust electrical safety. The undervoltage trip point is established at 280V AC for the 480V input voltage output, providing crucial protection against voltage fluctuations. Furthermore, this drive maintains a sound level of 59 dB at 190 CFM fan velocity while functioning. Its compact design permits operation at altitudes up to 1000 meters (3300 ft.) without requiring derating, making it suitable for various installation environments.
