The SP-142748 Transistor Kit is a transistor assembly that belongs to the Allen-Bradley 1336 series of drives and accessories. It is used to replace broken worn out, or outdated transistors from 1336 series AC drives. The SP-142748 Transistor Kit is suitable to use in 3-phase systems and a variety of frame sizes and drive types. It is designed to use power output circuits as switching and signal controlling transistor modules. The SP-142748 Transistor Kit offers fast switching capabilities with its highly efficient performance. This transistor kit is shipped with all the necessary accessories for installation. Before the installation of the SP-142748 Transistor Kit, make sure to clean the surface of the 1336 drive’s heatsink properly.

The SP-142748 Transistor Kit is a spare part that belongs to Series A of the 1336 spare parts products. It is installed on the main bus bar assembly in the 1336 drive. The transistor kit cannot function when the drive malfunctions.  It has a voltage rating of 575 Volts. The drive's terminal assembly has a transistor output terminal as an open drain output, another resistive transistor output terminal, and a common terminal for module connections. It is necessary to remove the power from the drive before the installation process. The users must remove the transistor snubbers and snubber connections from the drive to remove the old transistor before installing the new one. The Horsepower rating of the SP-142748 Transistor Kit is 75 to 200 Horsepower. The configuration process of the upper and lower transistor groups in the 1336 drive is different. The SP-142748 Transistor Kit can be used to upgrade or replace old transistor models. The 1336 drive contains paired transistors that can work with heavy-duty applications.
