They say the simplest products are often the best, and it's for that reason UK startup Power Ethernet has caught our eye. Founded by Andrew Delaware and based out of London, the company has developed ...

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 ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...

Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

For some applications such as extremely low-noise amplifiers or precision automated test equipment, it’s still possible to find a linear power supply at work converting AC utility power into some form ...

When I was in graduate school 10 years ago, a controls group proposed to the power-electronics center to use an advanced microcontroller in power supplies. This controller was to implement a new ...

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 ...
