Schematic Extra Quality - Wx-dc12003

Output caps: 220µF/16V + 0.1µF ceramic LED indicator: VOUT+ --- 1kΩ --- LED --- GND

| Op-Amp Section | Function | Key Components | | :--- | :--- | :--- | | | Voltage Error Amp | Compares V_SET (from pot) vs V_OUT. Drives pass transistors. | | U1B | Current Error Amp | Compares I_SET vs voltage drop across 0.1Ω shunt. Pulls down voltage ref if over current. | | U1C | Current Sense Amp | Amplifies shunt voltage (gain ≈ 11) for front panel meter. | | U1D | Voltage Follower | Buffers V_OUT for front panel meter. | wx-dc12003 schematic

: Approximately 80% with a no-load power consumption of less than 0.05W. Output caps: 220µF/16V + 0
