The Allen-Bradley 1336-BDB-SP30D is a PCB Gate Drive Board for AC drives. This spare part kit is used with 460 Volt AC-powered Allen-Bradley 1336 series AC drivers. It can only be used with “D” frame sized drives that are 100 Horsepower rated. This PCB Gate Drive Board is categorized in the most important group of Allen-Bradley AC drives spare parts (level 1 spare parts - major assemblies). You can find this spare part in catalogs in 1336STEF group denoted with 74101-169-54 (alternative part number). Spare part kits with 1336-BDB-SP30A and 1336-BDB-SP30C designations are older versions of this spare part kit. The Allen-Bradley PCB Gate Drive Board serves as an amplifier to control signals on 1336 series AC drives. As an input, it gets low power signal and then amplifies it to a higher power level control for switching IGBTs. This is one of the main components dedicated to perfect control of 100 HP motors.

The 1336-BDB-SP30D PCB Gate Drive Board interacts with other power and signal modules installed on the AC drive over six connectors designated with J2, J6, J7, J8, J9, J10, and J13. This is a spare part for obsolete drives. Before deciding to change this PCB check F1 and F3 fuses mounted on this PCB for an open condition. This PCB is located below the main control board on your 1336 series drive. The user must wear a wrist-type grounding strap during this board’s replacement. Wait a few minutes after the drive’s shutdown and check for zero voltage at DC current terminals to be sure that capacitors are discharged, then carefully remove all connectors from the board and screws that are holding it to the chassis.
