The Allen-Bradley 74101-169-94 printed circuit board is a circuit board spare part kit for the 1336 variable frequency drives that have also been manufactured by Allen-Bradley. It is a gate drive printed circuit board (PCB). The AC input voltage supply required for normal operation is 575 Volts AC. The output power rating of the drive is 300 Horsepower. The PCB is equipped with different components. The 74101-169-94 printed circuit board comes with a level shifter unit that consumes low power and converts it into a high current to power all the parts of the drive. It is fully compatible with the drives with the A, B, C, D, and E frames. The 74101-169-94 printed circuit board is housed below the main control board of the variable frequency drive. The PCB is easy to replace and the installation process can be done without excessive supervision and labor.

The Allen-Bradley 74101-169-94 printed circuit board kit provides outstanding and stable performance in a drive by distributing equal levels of power across the drive. The operating temperature of the 1336 drive should not exceed 50 degrees Celsius. The maximum altitude that is compatible with the normal operation of the drive is 1000 meters above sea level. No electromagnetic and electrostatic noise traces should be present in or near the installation environment. These noises are known to reduce the performance and to damage the internal components of the variable frequency drive. The 1336 drive is a 3-phase device that is made to regulate the torque of an induction motor in an industrial setting. The drive is an ideal solution for control applications.
