20BD481A3ANNNNC1

The PowerFlex 700 series includes the 20BD481A3ANNNNC1 adjustable frequency AC drive, which is specifically engineered for demanding industrial functions. It operates effectively at a rated supply voltage of 480 volts AC, making it suitable for a variety of applications. With a maximum current handling capacity rated at 481 amperes, this drive is designed for excellent performance in high-load settings.

Central to its operation is the sensorless vector control unit, which supports input and output at 24 volts DC. This technology ensures precise control of motor functions, contributing to efficient performance. The drive is designed with an RS-485 physical interface, allowing for effective connectivity within automated systems.

The device incorporates notable protection features including a bus overvoltage trip set at 810 volts DC, designed to safeguard against electrical surges. In terms of input voltage management, it also features overvoltage and undervoltage trip settings of 570 volts DC and 280 volts DC respectively, ensuring reliability and operational stability.

Housed in a NEMA/UL Type 1 enclosure with a conformal coating, the module is fortified against environmental contaminants, providing additional durability. However, it does not come with emission protection compliant with CE/EMC standards, which may be pertinent in certain applications.

Furthermore, the unit does not include a drive-mounted brake resistor or an insulated gate bipolar transistor (IGBT) for braking, making it important to consider additional braking solutions as needed for specific applications. Overall, the 20BD481A3ANNNNC1 is a robust solution within the PowerFlex 700 lineup, delivering essential functionalities for advanced motor control.
