The SP-140584 bridge rectifier kit is expertly designed for compatibility with the Bulletin 1336VT series of Allen-Bradley/Rockwell Automation variable frequency AC drives, specifically fitting models with B150 and B200 specifications. This kit is critical for converting AC to DC currents, essential for the precise speed control of motors in these drives. Positioned within the main chassis and at the bottom of the heatsink, each drive requires three kits to ensure optimal performance within a voltage range of 380 to 420 Volts AC and an output current rating between 218 and 290 Amps.
