About the 0-55306

The 0-55306 is a gate drive circuit board produced by Reliance Electric. This is a minimal circuit board and has three large transformers that run down the center of the circuit board. Each of the transformer’s tops is labeled 2X, 1X, H2, H1 and have a metal bracket that runs down the center. The top edge of the circuit board as three sets of two pins. Each set of pins is labeled as a separate group THY 1, THY 2, THY 3 The metal pins are also labeled individually. The below the first metal pin in each pair is labeled with a “K” and below the second metal pin in each pair is labeled with a “G”. Above the first metal pin in the pair is labeled with a “R” and above the second metal pin is labeled with a “W”. Below these pins is a row of three dark brown resistors with bands. Below these dark brown resistors with bands is a line of three solid black resistors. Then is the row of transformers that was mentioned earlier. Below the transformers at the bottom of the circuit board are three sets of two metal pins. The first metal pin in each pair is labeled with a “W”. The second metal pin in each pair is labeled with an “R”. On the bottom edge of the circuit board is the part number 0-55306 and the Reliance Electric company logo. The 0-55306 is also a “daughter board” which means it can sit on top of another circuit board. The circuit board can do this using the short posts on the bottom of each corner that screw into place.
