About the 78177-2X

The 78177-2X is a Rectifier/thyristor assembly from Reliance Electric. Some of these parts were marked as originating from Baldor Reliance or Asea Brown Boveri, depending on the year of manufacture. This is the same part and documentation can be used regardless of the name on record. The 78177-2X is two rectifier stacks (copper/selenium oxide) connected across an air gap populated with an SCR. The unit has a curved foot on one side with a bolted connection. The 78177-2X is primarily used to convert AC (alternating current) to a more stable DC (direct current. The unit includes a gate coupling card located at the zenith of the two stacks. This board interconnects the stacks and acts as a gating component to allow the thyristor to be in an on or an off state. This gating card includes a capacitor, several wire jumpers, and other wired components. The 78177-2X should only be installed or maintained by well-trained individuals. Please consult with the original documentation for proper installation and handling procedures. This documentation will also include warnings and other information that should be read before the unit is unboxed.
