The SP-151132 base driver board by Allen-Bradley/Rockwell Automation is a critical component designed for the 1336 drive series, enhancing its functionality by supporting terminal blocks and vital electrical components. This board includes a power supply PCB kit and is strategically accessible from the front of the drive, encompassing both TB5 and TB6 terminals for managing power distribution efficiently. Ideal for drives with B005 specifications and frame sizes, it operates within a voltage range of 380 to 460 Volts AC and is essential for maintaining optimum performance in variable frequency drives used with variable speed motors, especially when the existing board shows operational deficiencies.
