Products Description

The Allen-Bradley SP-151140 PC Board is a specialized industrial printed circuit board (PCB) used as a replacement component within Allen-Bradley 1336 series adjustable frequency drives. It typically serves as the base driver and power supply board in drive systems rated around 40–50 HP and supporting 380–460 VAC applications. As an original equipment spare part, the board is engineered to restore electrical performance and maintain drive reliability when the original PCB has deteriorated or failed.
