The Allen Bradley PowerFlex 700 model 20BD156F2ANNANC0 serves as a highly capable adjustable-frequency AC drive. It is built to sustain a continuous current of 156 A while being engineered for high performance in rigorous environments. Additionally, it can handle temporary overloads up to 188 A for one minute and achieve short burst outputs of 250 A for three seconds. This drive is ideal for both normal and heavy-duty motor requirements, supporting motor power ratings of 125 HP and 100 HP respectively.
Designed for straightforward flange mounting, the drive is classified with an IP20 rating, allowing it to fit into environments where dust and moisture exposure are limited. Its advanced control capabilities include V/Hz and a sensorless full vector mode, providing flexible operational control. With a PWM frequency of 4 kHz, it ensures smooth and robust motor performance.
The unit features an overvoltage trip point of approximately 570 V, maintaining operational safety under varying electrical conditions. Notably, this drive boasts an efficiency rating of 97.5%, reflecting its capability to minimize energy consumption. The latency for digital I/O is around 9 ms, allowing for quick responses in control systems. Torque regulation achieved without feedback is within ±5%, ensuring reliability in performance throughout its operation.
