The Allen Bradley 20BD248A3NNNANN0 is an advanced adjustable frequency AC drive within the PowerFlex 700 series, engineered for industrial performance. It operates at an input voltage of 480V AC and is configured for three-phase supply, making it well-suited for high-demand applications. With a rated continuous output current of 248 amps, this drive provides a formidable 200 horsepower.
The drive supports a maximum output frequency of 400 Hz, with the option to extend to 420 Hz if required, thus providing operational flexibility. Inputs and outputs are efficiently managed with six digital inputs, three digital outputs, alongside two analog inputs and two outputs, allowing for diverse connectivity options tailored to various control systems.
This model includes a dual-channel encoder input working at 12 V DC, providing precise feedback for accurate motor control. The 20BD248A3NNNANN0 is constructed with an IP20-rated enclosure, compliant with NEMA/UL Type 1 standards, ensuring adequate protection against environmental factors. Additionally, it features a conformal coating that enhances resistance to moisture and contaminants.
The operator interface consists of an LCD display combined with a full numeric keypad, facilitating user-friendly operation and monitoring of the drive parameters. Although equipped with both a CE filter and a common mode choke to manage electrical noise, this unit does not incorporate IGBT technology or an internal brake resistor, focusing on streamlined control solutions.
