Description

Circuit diagram like in figure 1 above is Circuit Diagram Stabilized Power Supply With Short-Circuit Indication. According Electronicsproject site describe that this is an efficient 4-stage stabilized power supply unit for testing electronics circuits. It provides well regulated and stabilized output, which is essential for most electronics 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 ‘under test’ can be cut-off immediately to save the valuable components from damage.

The circuit provides four different regulated outputs (12V, 9V, 6V and 5V) and an unregulated 18V output, which are selected through rotary switch SW2. The selected output is indicated to the output rails.

The circuit uses a standard 18V–0–18V, 500mA step-down transformer to generate 18V AC. A rectifier diode comprising diodes D1 and D2 provides 18V DC, which is smoothed by capacitor C1 and given to the combination of regulated ICs (IC1 through IC4). The regulated ICs produce fixed, regulated outputs of 12V, 9V, 6V and 5V, respectively, which and connected to the rotary switch contacts. The power supply for loads requiring up to 200mA current.
