The Portable Variable Power Supply features a DC-output that can be easily changed by the user. As its name implies, this power supply is portable, making it invaluable in various circuit projects.

Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

Surprising facts, like “old fangled” 3-leg linear regulators (LM317, LM337, LM350, et al.) can be used in shunt regulator topologies can sometimes inspire “new fangled” circuit designs. Figure 1 shows ...

When you’re testing or debugging some mains-powered gear, plugging it directly into the outlet can often be an exciting proposition. If such excitement is not really your thing, you can opt for an ...

Every automated system that tests electronic circuit boards, modules, or equipment needs one or more DC power supplies. DC supplies provide power to the device under test as well as test stimulus. For ...
