Definition: What is a Programmable Power Supply
A benchtop power supply is an electronic test instrument that is used to supply an electronic circuit with power in order to test it.
Every electronic product has a power supply in it to supply the electronic components with the correct voltage and current to operate on. The difference between a bench-top power supply and such a build-in power supply is that the voltage and current of the build-in power supply is limited to the requirements of that single product while the voltage and current of a bench-top power supply can be adjusted over a wide range. It also often have multiple outputs to power multiple circuits.
