Allen-Bradley Precharge PCB Board 1336-PB-SP5A 460V

Used in Allen Bradley 1336 series adjustable frequency AC drives, the 1336-PB-SP5A is a precharge printed circuit board assembly rated for 460 VAC operation. This board serves drives in the 40 to 60 horsepower range and is compatible with 1336 Plus, Plus II, Force, and Impact drive families in CB (circuit breaker) style configurations. The PCB part number printed on the board is 74101-505-51, Rev 08, with date code 3203 and tracking identifier MSM000127. The board carries the Allen Bradley (A B) logo and is marked "Made in U.S.A." on the component side.

The precharge circuit functions to limit inrush current during drive startup, protecting internal bus capacitors and power semiconductors from damage. Visible components on the board include test points TP1 through TP10, multiple resistors, diodes, capacitors, integrated circuits (MC74HC08AN logic ICs, LM393 comparator, Z80 processor), connectors J1 through J3, and discrete semiconductors. The spare parts kit label on the board confirms the catalog number 1336-PB-SP5A.

This unit is packaged in an antistatic ESD bag with pink convoluted anti static foam inside a cardboard shipping box, consistent with original factory spare part packaging. The board appears to be in new surplus condition based on the clean solder joints, absence of flux residue or heat discoloration, and intact protective packaging. All 1336 drive families have been discontinued by Rockwell Automation, making this precharge board available only through surplus and aftermarket channels. The board includes four mounting holes for direct installation into the drive chassis.
