About the 0-55307-1
0-55307-1 Power Supply Board
The 0-55307-1 is a Power Supply Board manufactured by Reliance Electric. Most boards of this type will be marked as Reliance components; however, in some cases, this product may originate from Baldor-Reliance or more rarely from Asea Brown Boveri. The 55307-1 number will always be part of the component id.
The 0-54200-1 is a smaller board. Like most in this series, it has a grid pattern printed across its top surface. It does not have any sort of faceplate, nor does it have extraction clips. The 0-54200-1 is drilled three times along each long board edge to allow for mounting.
The 0-54200-1 has a potentiometer placed in one corner of the board. This component is marked “IET adjust.” It has two large components mounted vertically into a metal plate that is screw mounted to the board. These components connect to the board using surface wiring that connects to stab-on connectors.
Other components on the 0-55307-1 include integrated circuits, TP test points, stab-on connectors, disk capacitors, ceramic capacitors, electrolytic capacitors, transistors, metal film resistors, and diodes. Most stab-on connectors and test points are marked with some sort of reference designator, but other components typically are not marked. The rear surface of the board carries codes like 381, 705354-52A, and 904.
More information regarding the installation, maintenance, and operation of the 0-55307-1 may be found through publications originally provided by Reliance Electric. These include manuals, user guides, and data sheets. Reliance was responsible for all technical support for this product.
