The 1336-PB-SP22C from Allen Bradley is categorized as a precharge board, focusing on the requirements of the PowerFlex 700 drive series. This component interfaces directly with the drive's DC bus, providing essential support for frames 5 through 10 within the series.
Operating on a voltage class compatible with 540V DC inputs, this precharge board employs an internal precharge circuit that efficiently charges DC bus capacitors. This feature safeguards sensitive components from inrush current. An important interlock requirement is established to ensure safety during operation, mandating the use of a disconnect switch. The device is deemed sensitive to electrostatic discharge (ESD), underscoring the need for careful handling.
Installation of the 1336-PB-SP22C is straightforward, as it is engineered for direct replacement of earlier board types. It maintains operational effectiveness within an environment ranging from 0 to 50 degrees Celsius, ensuring reliable performance in typical working conditions. Overall, the precharge board serves a crucial role in maintaining the integrity and efficiency of PowerFlex 700 drives.
