The SP-151171 Kit by Allen-Bradley/Rockwell Automation, part of the 1336 series, includes a Base Driver Board and Power Supply PCB designed specifically for replacing components in adjustable frequency AC drives, especially those adhering to the B060 specifications. This kit supports drives operating with an 85 Amp output and an AC voltage range of 380 to 460 Volts, crucial for applications involving variable-speed motors, offering precision in controlling motor speed, acceleration, and deceleration. Engineered for installation inside the drive, the kit provides the necessary low and high-voltage supplies through its TB4 and TB6 terminal blocks, all the while requiring effective cooling to maintain optimal performance in environments not exceeding 40 degrees Celsius.
