About the 418285-113A
418285-113A PSBD-4A Board
The 418285-113A is a PSBD circuit board fashioned by Reliance Electric. This is a large board component that uses high-voltage power. It is important to note this circuit board carries some hazards when working with or installing it. Please be sure only qualified technicians with proper training handle this board.
The 418285-113A is drilled in each corner and also along the edge of the board. Nylon spacers have been inserted in each of these drill holes. The board has multiple connectors on its surface, including five header connectors along its top edge and four header connectors along its bottom edge. Other board components include ten inductor coils of various sizes, seven transformers, three relays, as well as multiple high-voltage electrolytic capacitors, disk capacitors, integrated circuits, resistors, transistors, diodes, heat sinks, and fuses mounted in fuse holders. Most board components are marked with both a reference designator and with their original manufacturing codes to make identification easier.
Your original board component may have shipped from the manufacturer with technical support publications like product manuals and data sheets. This printed material is an excellent resource for more detailed information regarding the operation of or proper installation of this circuit board. If these publications are no longer available, our team will be happy to help you with sourcing replacements. Reliance Electric was responsible for all original technical support for this product; however, sometimes these technical support guides can now be found through Baldor-Reliance or ABB, due to parts of Reliance being integrated with those companies.
