With the number 20BD156F0ANNARC0, Allen Bradley presents an adjustable-frequency AC drive within the robust PowerFlex 700 series. It effectively manages a 480 V AC input supply that operates in a 3-phase configuration at 60 Hz. This model is rated to deliver an output current of up to 156 A continuously and can support motors with power requirements of 125 HP under normal conditions and 100 HP under heavy-duty operation.
The drive is equipped to handle current peaks, reaching up to 250 A for brief periods of 3 seconds and allows for temporary overloads of 188 A for up to one minute. The output voltage can vary from 0 to 460 V AC, accommodating diverse motor requirements. It features a DC bus with a nominal voltage of 648 V DC and includes critical safety measures, such as bus overvoltage and undervoltage trips set at 810 V DC and 305 V DC, respectively. Furthermore, the input undervoltage trip activates at 280 V AC, ensuring robust protection against potential faults.
For circuit protection, the drive is compatible with a maximum circuit breaker rated at 450 A and can be adjusted to support a maximum motor protector of 250 A. The control options include both vector and V Hz types, with an output configuration providing 24 V I/O. The drive also features a logic ride-through capability, providing a minimum of 0.5 seconds and a typical ride-through time of 2 seconds, which can help maintain operational stability in the event of momentary power disruptions. Overall, the 20BD156F0ANNARC0 drive allows for efficient and precise motor control across various applications.
