The 1336-PB-SP23C PCB board is Precharge enabled PCB board that has been designed and manufactured by Allen-Bradley. It is a spare part for the adjustable frequency AC drives from the Allen-Bradley catalog. A PCB is a printed circuit board which connects electronic components by using conductive tracks from 1 sheet made of copper laminated layers. PCB boards are found in almost all electronic devices. A Precharge PCB board is used to protect an industrial machine system and to avoid contactor failure due to high levels of inrush current from capacitors. The 1336-PB-SP23C PCB board runs with 460 Volts AC supply voltage. The output power rating of the module ranges from 60 to 600 Horsepower. The module is mounted in the drive board by using screws on the back of the board. The Precharge PCB board is used with all the Allen-Bradley 1336 series variable frequency drives.
