The Allen Bradley PowerFlex 70 drive, specifically the part number 20AD027M0AYNANNN, is engineered for reliable performance in adjustable frequency applications. Rated at 20 horsepower, equivalent to 15 kilowatts, it operates efficiently at an input voltage of 480 volts AC and maintains a nominal output current rating of 27 amperes.
This model employs a standard control method, foregoing Safe Torque Off features and is designed specifically for 3-phase operations in a 6 pulse configuration. The nominal bus voltage is recorded at 648 volts DC, with vital trip points for overvoltage and undervoltage situations clearly defined at 570 volts AC for input overvoltage and 280 volts AC for input undervoltage, ensuring that equipment protection is prioritized.
Bus overvoltage trips are set to activate at 810 volts DC, allowing for prompt corrective measures in case of irregularities. Lacking a human interface module, the drive is characterized by a blank cover on its operator interface. Additionally, the robust NEMA Type 1 enclosure (IP20) is designed to shield the internal components effectively, aided by a conformal coating for enhanced resistance to environmental conditions. For braking applications, this drive is equipped with a brake IGBT (Insulated Gate Bipolar Transistor), facilitating swift and effective stopping capabilities.
The frame size for this model is designated as size D, establishing its physical dimensions within the PowerFlex series. It also adheres to emissions standards, incorporating a CE filter to comply with relevant regulations and improve electrical compatibility across various operational scenarios.
