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 ...

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original parts. But when said power ...

Switched-mode power supplies are found in electronics all around us. They provide the DC voltages that power our computers, cell phones, chargers, appliances, and myriad other electronic devices.

An effective and long-lasting power supply is the backbone of any IoT device. Switch-mode power supplies (SMPSs) are undoubtedly good for powering IoT devices, but most of them are bulky and expensive ...

GarrettCom, Inc. has extended the capabilities of its 6-port Magnum ES42 Edge Switches and ESD42 Dual-homing Edge Switches and PES42P Power-over-Ethernet Edge Switches with a line up of IPS42 ...

Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

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 ...

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 ...
