Product Description

The 0-51378-34 is a PC board gate coupling card from Reliance Electric.  This is a very small circuit board component that is typically used along with Reliance rectifiers to convert or change incoming AC current to DC, which is more stable and easier to operate.   Reliance Electric has merged and/or restructured several times over the decades, which means your part may have been marked as coming from Asea Brown Boveri/ABB or Baldor-Reliance instead of Reliance Electric. In most cases, parts with the same part number from all of these companies will be covered under this description. 

The 0-51378-34 is typically placed on the top surface of a Reliance rectifier stack and acts as a gate coupler.  The board is designed with two parallel, factory-drilled holes.  These have been reinforced on the bottom surface of the board for easy mounting.  There are only a few components mounted to the board’s surface due to the limited surface area of the small board.  This includes diodes, pin connectors, and metal film resistors.  The board also has a single, centrally placed transformer located on its surface. 

Reliance Electric publications such as user guides, manuals, and data sheets can be used to obtain more information about the 0-51378-34 circuit board, including important information regarding the safe handling of the board during installation procedures.  This should be reviewed before any type of installation begins.
