Digital benchtop power supply schematic.

Power supply is based around a lm723 voltage regulator chip and has current limiting. An old pc power supply unit makes an excellent and cheap bench top power supply for the electronics constructor. This variable power supply is using 7805 7809 7812 or 7815 voltage regulators where the last 2 digits desktop pc linear power supply circuit p. A benchtop power supply is a tool for testing and measuring circuit systems by providing direct current dc voltage power to the device under validation.

Presented here is a circuit for 30v 10a variable bench power supply that offers variable voltage and current adjustment. They range from linear purely analogue supplies with only voltage regulation to switching supplies. I often end up with the power clips shorting out on the bench and with no problems. Every electronics laboratory needs a powerful regulated bench supply.

In the model described here a microcontroller monitors the actual and desired current and voltage settings there are many types of laboratory benchtop power supplies available from the very simple to the highly sophisticated.
