Description

The 1336-BDB-SP34D PCB from Allen Bradley serves as a gate drive circuit assembly, integral to IGBT gate control systems. This component is rated for high-voltage operation at 575 VAC, suitable for high-performance applications. It interfaces directly with the 1336 drive platform and is typically mounted on the main control plate, securing it firmly with eight screws.

Typical applications include 125 HP drives that require precise gate signal management. This PCB’s operation hinges on the generation of PWM gate pulses, which effectively control the connected IGBT devices. An auxiliary input rated at 24 VDC (TB4) allows for additional functionality within the system.

For users needing to perform diagnostic checks, the board provides access to diode tests across components VR1 through VR6, facilitating easy verification of operational integrity. This printed circuit assembly is specifically designed to capture and intelligently manage the control signals necessary for high-efficiency operation in designated 575V drives, ensuring optimal performance in demanding scenarios.
