DC Stabilized With Short Circuit Indication

Description

The Stabilized with Short Circuit Indication is an efficient 4-stage stabilized power supply unit for testing electronic circuits. It provides well-regulated and stabilized output, which is essential for most electronic circuits to give proper results.

The Stabilized Power Supply kit with Short Circuit Indication 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 selectable through a DIP switch.

The selected output is indicated on the analog voltmeter connected to the outputs rails. The regulator ICs produce fixed, regulated outputs of 12V, 9V, 6V, and 5V, respectively, which are connected to the DIP switch. This Power Supply Short Circuit Indication is useful for loads requiring up to 200mA current. Complementary 2 transistors conduct when the power to the circuit is switched on. The full selected supply voltage is available at the collector of the transistor, which is used to power the load.
