The Allen Bradley 20BD011A3AYNADC0 is an adjustable-frequency AC drive tailored for various industrial applications. It functions effectively with a 3-phase input of 480 V AC and operates at a frequency of 60 Hz. The drive features a nominal DC bus voltage of 648 V DC, ensuring compatibility with industrial standards.
For safety, the DC bus trips at under-voltage (UV) and over-voltage (OV) thresholds of 305 V and 810 V respectively, while the AC line trips at UV 280 V and OV 570 V. This model requires upstream protection with a circuit breaker rated at ≤ 40 A, and can accept microprocessor protection at ≤15 A with fuses ranging from 15 to 40 A.
In terms of performance, the drive allows continuous output current up to 11 A and can handle short-term overloads of 12.1 A for one minute and 16.5 A for three seconds. The maximum output frequency attains up to 420 Hz, making it versatile for different motor speed requirements.
The 20BD011A3AYNADC0 also integrates DeviceNet communication capabilities, enhancing its functionality within automated systems. The carrier frequency can be adjusted to 2 kHz, 4 kHz, 8 kHz, or 10 kHz based on application needs. Furthermore, this drive achieves speed accuracy of 0.1% and maintains torque performance within ±5%, ensuring reliable operation across various conditions.
