Product Description
0-51902-5A Driver Circuit board
The 0-51902-5A is a Reliance Electric circuit board component. This board is designed for use within Reliance drives. In most cases, it will carry the Reliance logo. However, due to changes in company structure, in rare situations this board may originate from ABB or from Baldor Reliance. The 51902-5A number will still be reflected in the part ID number.
Unlike many boards in this series, the 0-51902-5A does not have a connected front faceplate. The board has a printed grid pattern on its surface, and this is marked on its leading edge with numbers that run from zero to 95 in fives. The other grid axis is denoted by letters. The rear edge of the board extends in a conductive backplane.
The 0-51902-5A is populated by lines of resistors. The board has a single large electrolytic capacitor that has been secondarily supported and connected to the board. The board has additional capacitors made from polyester vinyl and ceramic material. A line of stab-on connectors is placed near the front edge. These are individually labeled. Other components on the board include transistors, integrated circuits, diodes, and four transformer components.
Publications originally provided by Reliance Electric will have more information regarding board operation and proper installation techniques. This includes manuals, data sheets, and series user guides. Please read and follow all handling procedures.
