The Allen Bradley 20BD248A3NNNANB0 adjustable frequency AC drive stands out for its robust design and high performance. This device is structured to operate within three-phase power systems, featuring a maximum current handling capability of 248 Amps. It is rated for 480V AC and designed to run efficiently at a frequency of 60 Hz, making it suitable for various demanding applications.
Encased in a compliant IP20 enclosure, this drive is constructed to meet NEMA/UL Type 1 standards, ensuring protection against dust and debris in non-hazardous environments. The unit employs a conformal coating that enhances protection against moisture and physical contaminants. Additionally, it does not have an internal brake resistor or a brake IGBT, allowing for a simplified design focused on efficient performance.
User interaction with the drive is streamlined through its LCD display combined with a full numeric keypad, enabling quick adjustments and monitoring. The drive supports a comprehensive I/O configuration with 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs. It also features an encoder input option that operates on 12 V DC with dual-channel support and a maximum output of 250 mA. The drive can achieve an output frequency of up to 400 Hz, with an optional extension to 420 Hz for specific applications. The inclusion of both CE filter and common mode choke ensures that the drive remains compliant with electromagnetic compatibility standards.
