About the 0-51378-12
The 0-51378-12 is a Gate Coupling Board constructed by Reliance Electric. This board may have also been manufactured by ASEA BROWN BOVERI, Allen Bradley, or Baldor Reliance depending on the year it was in production.
The 0-51378-12 is a printed circuit board that can be used as a diode substitution. This coupling board can be used with an 86475-11S Rectifier Stack. The 0-51378-12 is made up of several key parts including wired connectors, diodes, terminal pins, and dual resistors. This card is attached to the top of a heat sink on the rectifier stack or phase rectifier module. A rectifier stack is a device used to convert unpredictable AC current to a more manageable one-way flowing DC current. It does this by using a pair of thyristors to pulse at a specific point in the AC power cycle.
More information about the 0-51378-12 and the rectifier stack it attaches to can be found in the original Reliance Electric product manuals. Please refer to them before trying to attach the 0-51378-12 to its rectifier. Only a qualified professional should install this board.
