Stablised Power Supply With Short-Circuit Indication circuit

Here is an efficient 4-stage stabilised power supply unit for testing electronic circuits. It provides well regulated and stabilised output, which is essential for most electronic circuits to give proper results. The circuit provides an audio-visual indication if there is a short circuit in the PCB under test, so the power supply to the circuit Ëœunder test can be cut-off immediately to save the valuable components from damage..
