The 20BD156A5AYNACC1 is a versatile adjustable-frequency AC drive from Allen Bradley's PowerFlex 700 lineup. This drive's nominal input voltage is rated at 480 V AC, providing flexibility with a comprehensive voltage range of 342–528 V AC for three-phase systems. Continuously, the unit delivers a robust output current of 156 A, accommodating applications with motor ratings of up to 125 HP in normal duty operations and 100 HP in heavy-duty scenarios.
The unit complies with an IP20 / Type 1 enclosure rating, ensuring adequate protection in environments suited for indoor installations. It features a braking transistor for enhanced control during deceleration, although it does not include an internal brake resistor. The device also offers a maximum output frequency capability of 420 Hz, facilitating applications requiring high-speed adjustments. Users can select carrier frequencies between 2 kHz and 10 kHz according to the specific requirements of their system.
The 20BD156A5AYNACC1 supports encoder feedback, which aids in enhancing motion control accuracy. For ambient conditions, this drive is rated to operate effectively within a temperature range of 0 to 40 °C under full load conditions. Control capabilities are established with vector control features, and the device accommodates 24 V DC I/O for increased operational versatility.
