20BD248A3AYNARC1

The Allen Bradley model 20BD248A3AYNARC1 serves as an adjustable frequency AC drive optimized for industrial applications that require precise motor management. It operates with a robust input voltage of 480V AC across a three-phase system. This drive is suited for high-performance environments, delivering up to 200 horsepower while managing a substantial current rating of 248 Amps.

The internal frequency is rated at 60 Hz, permitting it to maintain optimal performance in a wide range of settings. Additionally, the unit is capable of reaching a maximum output frequency of 400 Hz, with the ability to extend this to 420 Hz when required. Its construction includes an IP20 enclosure, complying with NEMA/UL Type 1 standards, ensuring protection against dust and minor contact.

A conformal coating further guards the internal components against environmental factors. The interface for user interaction comprises an LCD display and a full numeric keypad, allowing for straightforward configuration and monitoring of settings. Supporting input from a dual-channel encoder with a 12 V DC output at 250 mA enables enhanced motor feedback capabilities. The drive is outfitted with 6 digital inputs, 3 digital outputs, 2 analog inputs, and 2 analog outputs, providing flexibility for various control strategies. An integrated IGBT allows for efficient switching, while it is important to note that there is no internal brake resistor included in this model.
