The 1336-PB-SP23D board is a spare part for Allen-Bradley AC drives. It contains a precharge PCB for the 1336 PLUS, FORCE,  IMPACT, and PLUS II series solid-state drives from Allen-Bradley. One kit is required per drive and the 1336-PB-SP23D board is compatible with drives that have an input rating of 460 Volts AC and output ratings of between 60 and 600 Horsepower. The 1336-PB-SP23D board is compatible with multiple drive frames including Frames D, E, F, and G. For Frame D drives, the compatible output ratings are 60, 75, 100, 125, and 150 Horsepower. For Frame E drives, the compatible output ratings are 150, 200, and 250 Horsepower. For Frame F drives, the compatible output ratings are 250, 300, 350, 400, and 450 Horsepower. For Frame G drives, the compatible output ratings are 250, 300, 350, 400, 500, 600, and 650 Horsepower.

Any precharge board like the 1336-PB-SP23D board is used for the prevention of high inrush current. This helps to protect the AC drives from damage during startup and it enhances the reliability and the operational life of the drive. The 1336-PB-SP23D board is installed in solid-state drives from Allen-Bradley which are sensitive to electrostatic discharge. Precautions including the use of workspace that is free from static, the use of static-safe containers for components and drive parts, and the use of wrist straps that are grounded should be implemented to protect the drives and their components against electrostatic discharge. Furthermore, the electrical power supply to the drives should be disconnected prior to starting any repair or maintenance activities. Failure to do so can lead to electric shock.
