The 1336-151149 is a power base driver board for the 1336 adjustable frequency drive series. This part has been designed and manufactured by Allen-Bradley. The Allen-Bradley 1336-151149 power base driver board includes terminal blocks TB4 and TB6, which allow the drive power supply to be operated from an external voltage source. The Allen-Bradley 1336-151149 power base driver board is located between the main control board of the drive and the drive components. This driver board includes a bus indicator light and a fuse called the F1. Users can access it directly from the front of the drive. Some troubles caused by the malfunctioning of the Allen-Bradley 1336-151149 power base driver board are excessive current, up to 150% of the drive rating, a bus voltage rise of 10% above the nominal value, and an improper boost setting, that impedes the motor from developing enough torque to break away from the load.

When errors are present, the voltage at the TB terminals must be monitored, and this monitoring is carried out by the power base driver board. The Allen-Bradley 1336-151149 power base driver board has a microprocessor in it and it must be in constant communication with the main control board which is primordial to the correct functioning of all the parts in the system. This communication is possible by the means of a ribbon cable connected to both of them. The recommended conditions for this power base are a temperature range of 0 to 40 degrees Celsius and a relative humidity range of 5 to 95%. It is important to ground all the parts of the drive in order to avoid electromagnetic interference (also known as electrical noise).
