This is a succinct account of my experience with the cheap electronic power supply module from China, “DC-DC Module 5-A/7-W (ERPC0575DC) XL4015.” I have used quite a few over the years and have to say ...

[TheSignalPath] wanted to repair a broken Instek PSW80-40.5 because it has a lot of output for a programmable power supply — 1,080 watts, to be exact. This isn’t a cheap supply — it looks like it ...

In this post I’m going to share my thoughts on making a simple emergency power supply system for Raspberry Pi boards. Hopefully it will be cheaper and easier to build than a commercial version because ...

This file type includes high resolution graphics and schematics when applicable. Let’s face it: Some lucky folks don’t have to worry too much about power conversion. Just plug the board into the ...

Small solution sizes and high integration levels are required for extremely space-constrained systems, such as optical modules and solid-state drives (SSDs). While integrated power modules tend to be ...

Once upon a time, building yourself a power supply required sourcing all manner of components, from transformers to transistors, knobs, and indicators. These days, everything’s a bit more integrated ...

Power supplies are a frequently misunderstood—and overlooked—PC component. Many users choose a PC power supply based on total wattage alone, assuming that higher is always synonymous with better.

Decreased system reliability due to overloaded power supplies is a common engineering challenge. In this Q&A-style article submitted by Allied Electronic & Automation, David Norton, technical ...

Made by Cissoid and called CMT-PLA3SB12340, it can supply its 26A at 90°C, and up to 340A at 25°C. This is a complete power module, including output-to-baseplate (5kVdc for 1min) and input-to-output ...
