Description
The 1336-BDB-SP5D is a factory-original gate driver printed circuit board (PCB) manufactured by Allen-Bradley (Rockwell Automation). It is a critical internal component of the 1336 family of adjustable frequency AC drives—including the PLUS, PLUS II, FORCE, IMPACT, and REGEN series—functioning as the vital interface between the drive’s low-voltage control logic and its high-power IGBT/SCR switching devices.
Designed for 460V AC, 25-horsepower (18.6 kW), Frame B applications, the 1336-BDB-SP5D converts low-level PWM switching signals from the main control processor into precisely timed, high-current gate pulses that turn the IGBT power modules on and off. It is a Level 1 spare part, meaning one board is required per drive, and is typically stocked as part of a plant’s critical-spare strategy for maintaining legacy 1336-series assets.
Application Scenarios
Picture a food-and-beverage bottling plant where a 20-HP conveyor drive—powered by a 1336 PLUS II VFD—has run reliably for 15 years. One morning, the line goes down: the drive faults on “Overcurrent” followed by “Gate Fault,” and a visual inspection of the gate driver board reveals a discolored trace and a failed resistor network near the IGBT interface. The motor and power module test clean, but the drive will not run. A full VFD replacement would mean re-engineering the panel, re-terminating cables, re-entering parameters, and a multiday production stoppage.
By sourcing a tested 1336-BDB-SP5D gate drive board, the plant’s maintenance team performs a board-level swap in under an hour. The control parameters remain intact on the drive’s main control board; only the gate driver assembly is replaced. The line is back online the same shift, at a fraction of the cost of a full drive change-out. This is the practical, high-value role the 1336-BDB-SP5D plays in hundreds of MRO programs worldwide: keeping proven installed assets running without the cost and disruption of full system replacement.
