About the 0-51831-3
The 0-51831-3 is a CVTD drive module by Reliance Electric. The front of the 0-51831-3 a ten-peg black section drilled onto the front. The first opening is labeled COM, the second opening is labeled 100MV, the third opening is labeled 150MV (these three openings are all under the label +4V MAX / PIN 2 and ARM CURRENT FB.), the fourth opening is just labeled four (4), the fifth opening is just labeled five (5), the sixth opening is labeled 500V, the seventh opening is labeled 240V, the eighth opening is labeled 180V, the ninth opening is labeled 100MV, the tenth opening is labeled COM. The openings number six through number ten fall under this universal label of -4V MAX / PIN 4 and ARM VOLTAGE FB. The opening can also have wires with diodes, capacitors, resistors, etc. connected to them. Toward the back of the circuit board is small sections of wire only attached to the circuit board. There are a large number of capacitors of different sizes and shapes to store energy. The circuit board also has two small blocks that are potentiometers. To adjust the potentiometers, use the small screws on the side. The 0-51831-3 also utilizes ten transformers and three large transformers, along with over a dozen diodes and resistors.
