Velleman Lab power supply, programmable, adjustable, 0-30 VDC/0-5 A, current limit, short-circuit protection, LCD display, USB connection, grey

When you wish to test an electrical circuit, you often need to connect it to a power supply. You could use a mains adapter for this, but a lab power supply is much more suitable because it displays current and voltage, so you can see what is happening. With a lab power supply, you can also shield the test circuit so that the circuit under test is better protected. Lab power supplies come in a wide range of configurations. Before buying, it is best to check the functions of the lab power supply first. Is it linear or switched, digital or analogue? Thus, there are many models on which you can optimally regulate current and voltage. .
