About the 0-55325-21
0-55325-21 Voltage Regulator PC Board
The 0-55325-21 is a Reliance Electric board component that has been fabricated for use within the company’s drives. This particular board functions as a Voltage Regulator Board. In some cases, this board may have originally shipped from ABB or from Baldor-Reliance.
The 0-55325-21 is marked across its top surface with a grid pattern. This grid is marked along one axis by the numbers zero through 95, by fives. The other axis is designated by letters. Components on the board typically do not have reference designators.
The 0-55325-21 has five fuses mounted in fuse holders on the right side of the board. To the right of these, there are two lines of terminal pins and a single stab-on connector. Four more stab-on connectors are placed directly below the fuses.
Other board components on the 0-55325-21 include high-voltage electrolytic capacitors, polyester vinyl capacitors, disk capacitors, resistors made from metal film and others made from carbon composite material, along with several diodes. The board also has a single transformer, transistors, integrated circuits, and several surface wired connections. The board has mounting screws inserted into factory-made drill holes in each corner. Three lines of three screws are mounted into the body of the board, parallel to each other.
More information regarding the installation or operation of the 0-55325-21 can be found through Reliance technical publications, like data sheets or product manuals. Please ask your sales representative about these publications if they are not currently available to you. Reliance was responsible for providing technical support for all circuit boards in this series.
