The 20BD077A3NNNADC1 from Allen Bradley serves as an adjustable frequency AC drive, optimized for high-performance applications. It is configured for a three-phase system, providing a strong output capacity of 45 kilowatts at a voltage class of 480 volts AC. This model offers a nominal bus voltage of 648 volts DC, ensuring efficient operation.
A key specification of this drive is its ability to handle a current rating of 77 amperes. It also has a horsepower rating of 60, making it suitable for demanding loads. For transient scenarios, the drive can manage intermittent overloads of about 110%, assisted for durations of up to 60 seconds.
Communication and integration capabilities are enhanced through its DeviceNet network interface, ensuring effective connectivity with other components in the system. The feedback mechanism employs a dual-channel incremental encoder, which operates at 12 volts and 5 volts, with a typical duty cycle of around 50%.
User interaction occurs through an LCD display complemented by a full numeric keypad, providing straightforward access to various control options. In terms of design, the drive does not include a brake IGBT, opting instead for emission filtering using a CE filter along with a common mode choke, contributing to overall system stability.
