[Mike] just purchased this Atten APS3005S bench power supply for around $80. It does the job, but boy is it noisy! We were pretty surprised to hear it fire up in the video after the break. To make ...

Today, 80% of all input/output (I/O) devices in automation applications are supplied with 24VDC power. The second most popular voltage is 120VAC, which is used on 15% of all I/Os. Over the past decade ...

Editor’s note: In Part one, we looked at an intro and the basics of linear regulator and switching power supply operation. This final part two will look at design considerations of the switching power ...

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 ...

The Rhino line of power supplies includes several new metal and plastic-housed switching supply models. Rhino PSM series switching DC power supplies are available in 12VDC or 24VDC adjustable output ...

Today’s power supplies do more than deliver clean and stable dc power on daily basis—they provide advanced capabilities that can save you time and money. Bench power supplies come in all shapes and ...

In Figures 16 and 21, the power stage Gcv(s) with closed current loop is determined by the selection of power stage components, which are mainly decided by the DC ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

The proper installation of switch-mode power supplies in control systems is crucial to guarantee 24/7 availability and reduce problems associated with grounding faults, harmonic distortion, and other ...
