The 1336-BDB-SP38A board is a pre-charge gate drive board that can be used with adjustable frequency drives from the 1336 Plus, Plus II, Force, and impact series manufactured by Allen-Bradley. Adjustable frequency drives are meant to be used with variable speed motors whose primary functioning requires speed and torque variances. The Allen-Bradley 1336-BDB-SP38A pre-charge gate drive board operates with drives with a voltage rating of 460 Volts AC and an output rating of 200 Horsepower. This drive is in charge of inserting or removing the pre-charge board, its use can be affected by the same conditions that affect the drive, depending on the external housing. These conditions can be extreme temperatures and humid environments. It is important to avoid overheating to have an optimum functioning of all the parts of the drive.

The malfunctioning of the Allen-Bradley 1336-BDB-SP38A pre-charge gate drive board can be detected when there is no display message and when the display stays at zero hertz after starting the drive. The 1336-BDB-SP38A pre-charge gate drive board is in the circuit board platform and it is placed in the front part of the drive. To install it or remove it, it is necessary to stop the AC drive completely and then there is a series of steps to follow that consist mainly of disconnecting the connectors and jumpers. It can be installed as a replacement part once the current part has stopped functioning and it can be found in the accessories and replacement parts catalog available from Allen-Bradley. It is recommended to have an Allen-Bradley expert perform this installation to ensure that proper connections have been made.
