The SP-142693 Precharge Board Kit from Allen Bradley/Rockwell Automation, part of the 1336 series adjustable AC drives, is engineered to enhance industrial 3-phase induction motors. This microprocessor-controlled component serves as a bridge rectifier diode, efficiently converting AC to DC power and ensuring consistent DC voltage for high-power applications, specifically suited for C020-C030 rated drives. With a voltage output of 575 volts and a power range between 20 to 30 horsepower, this compact kit, weighing approximately 1.36 kilograms, is situated on the main chassis behind the control board in the drive, demanding careful and power-off installation for optimal safety and functionality.
