). This safely limits the maximum current output, preventing the power supply from destroying itself during a short circuit. 5. Step-by-Step Troubleshooting Guide

The traces connecting the bridge rectifier, bulk capacitors, pass transistor collector/emitter, and output terminals must be wide enough to handle peak currents. Use a minimum trace width of 100 mils per Ampere for 1-ounce copper, or beef up the traces by exposing them and adding solder bridges. Do you have the brand name Are you

Utilization of standard three-terminal linear regulators like the LM7805 (for ), LM7812 (for ), and LM7912 (for the negative

Understanding the schematic requires knowing the key pins and how they connect within the system. LM7812 (for )

Protects the entire board from overcurrent conditions caused by short circuits.
