The MAPS-1 Multi-Channel Power Supply board, otherwise known by the number 418285-79A, is a board component manufactured by Reliance Electric for use within the company’s various drives. This is a high-voltage board that should only be worked on by well-trained technicians.
The MAPS-1 is a narrow rectangular board without any type of faceplate or extruder attached. The board is drilled in six locations and has wide nylon spacers inserted into each of these. The board’s surface is marked with codes and warnings, including “High voltage zone DANGER,” “DANGER,” and high-voltage arrows. Connectors include two header connectors on the top edge, stab-on connectors, and a two-story terminal strip on the left edge. This component has two lines of five screws.
Other board components include rectifier diodes mounted in heat sinks, a glass fuse mounted in a fuse holder, potentiometers, a toggle switch, and four red LED indicators. The board also has several surface-mounted high-voltage electrolytic capacitors, several transformers, a relay component, and transistors. Resistors may be carbon composite or metal film. Capacitors vary from electrolytic to ceramic to other materials. The board has several integrated circuits. Additional markings are located on the rear surface of the board.
