The Rockwell Automation/Allen-Bradley 1336-BDBMX3-SP34D is a conformal-coated printed circuit board gate drive. The drive is meant to be used with adjustable frequency drives. The 1336-BDBMX3-SP34D is operated with an AC power supply with a voltage rating of 575 Volts AC and it is rated to be used to control induction motors with a Horsepower rating of 125 Horsepower. The conformal coating allows the gate driver board to be used in industrial environments with extreme temperatures, humidity, dust, and other harsh conditions.

The 1336-BDBMX3-SP34D belongs to the Allen-Bradley 1336 family of variable frequency drives. Drives in this series control motors that align with the specific needs of industrial applications. Additionally, drives in this series, including the 1336-BDBMX3-SP34D, are prone to static discharges emanating from static electricity, making it necessary to have static control mechanisms in place when handling the drives. The static control measures ensure proper grounding when installing, servicing, or uninstalling the 1336-BDBMX3-SP34D and other drives in the 1336 family. The 1336-BDBMX3-SP34D provides an onboard terminal block to interface the drive with external devices. It also has snap-in ports for onboard connections. When installing the 1336-BDBMX3-SP34D, as with other drives, make sure to lock out all incoming power to prevent injury to personnel and damage to the drive or other drives being interfaced with the 1336-BDBMX3-SP34D printed circuit gate driver. Note that the parts carrying the bus voltage on the 1336-BDBMX3-SP34D are likely to carry an electric current before the bus discharges completely for some time after disconnecting the 1336-BDBMX3-SP34D gate driver board from the power supply.
