Digital benchtop DC power supply / Mazli Shahar Mohamed

A low-current power supply is a must for testing and experimenting electronics and other related areas. The main objective of this project is.to facilitate the normal procedure- of using available dc power supplies. In normal applications, -while reading dc voltage. It is necessary to read the current consumption too. Thereby, in order to' get the reading, the circuit in testing has to be broken and an ammeter be placed between the power supply and the load circuit and only then, the current output can be obtained. In this, it is not necessary to do as the above. Instead, by just pushing the pushbutton switch marked "VOLTS / mA" from dc volts to dc mA or vice-versa, the readings of the voltage and current can be obtained, without, breaking the circuit.
