Benchtop power supplies play a key role in testing electronic devices during design and development.

Benchtop DC power supplies have long been an essential ally for engineers and technicians in electronic test and measurement applications. These power supplies power the devices under test, whether printed circuit boards, printed circuit boards or electronic products. Benchtop DC power supplies are essential to ensure that a product performs as expected before it is shipped.

Over the years, benchtop DC power supplies have evolved to offer greater accuracy and reliability, greater programmability, and more features. But their basic functions and purpose have remained the same, and it is necessary to understand how these instruments work to get the most out of them.

Test and measurement supplier Rohde and Schwarz recently released a video, “Understanding Benchtop Power Supplies,” which provides a general technical introduction to benchtop DC power supplies and explains the most important functions, parameters, and features of these instruments in modern test and measurement applications. . Topics covered include specifications such as output voltage, current, and power; derating curves; instrument setup; reread; protective functions; and more.
