Product Overview
The Allen-Bradley 1336-BDB-SP6D Gate Driver Board is a critical printed circuit board (PCB) assembly designed for the 1336 series of AC variable frequency drives (VFDs) manufactured by Rockwell Automation -3-4-8. This component serves as the essential interface between the drive’s low-voltage control logic and its high-power Insulated Gate Bipolar Transistor (IGBT) modules, converting low-power PWM switching signals from the main control processor into precisely timed, high-current voltage pulses that drive the IGBT gates -8. The 1336-BDB-SP6D Allen-Bradley gate driver board is fundamental to the operation of the drive, directly governing the switching characteristics that determine motor speed, torque, and overall system efficiency -8.
The Allen-Bradley 1336-BDB-SP6D is specifically compatible with 30 horsepower, 460V AC, “B” frame sized drives within the 1336 series, including the 1336 PLUS, 1336 PLUS II, 1336 FORCE, 1336 IMPACT, and 1336 REGEN product lines -1-4. It is classified as a Level 1 major assembly spare part kit, meaning it is a primary replacement component for repairing these drives -1-4. As a direct replacement for the obsolete part number 1336-BDB-SP6C, the 1336-BDB-SP6D allows for targeted repair of the drive’s inverter section without the need to replace the entire unit, significantly reducing both downtime and operational costs -4-9.
Integral to the drive’s power stack, the 1336-BDB-SP6D Allen-Bradley incorporates advanced protection circuitry, including desaturation detection, under-voltage lockout (UVLO), and soft shutdown logic -8-9. These features are designed to safeguard the expensive IGBT power modules from catastrophic failure modes such as shoot-through or overcurrent events, making it an indispensable component for maintaining the reliability of the extensive installed base of 1336 series drives in industrial environments -8. Its precise engineering ensures that the original switching performance and efficiency of the drive are fully restored upon replacement -9.
