The 1336-BDB-SP56C gate drive board is an AC gate drive board that has been manufactured, designed, and distributed by Allen-Bradley/Rockwell Automation. This gate drive board can work with the 1336-STEFR bulletin of 3-phases adjustable frequency AC drives (in the Plus, Force, Impact, Plus II, and Regen series). The 1336-BDB-SP56C board consists of a gate drive board that can be installed as a replacement part once the current part has stopped working or if it is having problems during operation. This part can be found in the spare parts catalog of the 1336 series drives.

The Allen-Bradley/Rockwell Automation 1336-BDB-SP56C AC gate drive board is an important part when it comes to the overall functioning of the host AC drive. By being a circuit board, it provides electronic features to the drive and it is in charge of controlling the human-machine interface of the AC drive. It is located in the front panel of the drive, connected to several jumpers, and compatible with 460 Volts AC and 150 Horsepower rated drives. The gate drive board is contained in the main circuit board and it is extremely sensitive to electrostatic discharge, under these circumstances it is recommended to use tools to avoid ESD contamination. Depending on the housing of the AC drive, the Allen-Bradley/Rockwell Automation 1336-BDB-SP56C AC gate drive board can operate at a maximum operating temperature of 50 degrees Celsius. This level should not be exceeded since the drive can overheat and cause damage to any of its parts. Circuit boards as this one are sensitive to electrostatic discharge. The circuit board is the heart of any AC drive.
