Description
🔹 Product Introduction
The Allen-Bradley 1336-BDB-SP49D is a Gate Driver PCB for the 1336STEF adjustable-frequency drive family. Rockwell Automation’s spare-parts documentation identifies it as a 575 V, 400 HP, G-frame gate-driver board for 1336STEF drives. The earlier 1336-BDB-SP49A and 1336-BDB-SP49C versions were replaced by the SP49D version.
This board is intended for drive maintenance, repair, and replacement applications where the existing 1336STEF drive requires a compatible gate-driver assembly. The complete catalog number should be matched with the drive’s voltage, horsepower, frame size, and series before installation.
