Parallel Mode Problems: How to Troubleshoot a Parallel DC Power Supply When a single DC power supply cannot provide enough current for an electronics test, connecting multiple outputs in parallel mode can be an effective solution. However, parallel operation can also introduce problems. You may find that the parallel DC power supply is not...

How to Test a PCB Power Rail with a DC Power Supply: A Practical Troubleshooting Guide When a PCB does not power on, resets unexpectedly, draws too much current, or becomes unusually hot, the problem may be related to its power rail. A DC power supply is one of the most useful tools for...

Why does your power supply voltage drop when connected to a load? This guide explains voltage drop causes, current limitations, power capacity, and solutions for electronics testing, battery applications, and industrial equipment.

How to Choose a High Current DC Power Supply? When selecting a DC regulated power supply, many users focus first on output voltage, but for industrial testing and development applications, current capability is often the key factor that determines whether the power supply can operate reliably. A power supply with insufficient current capacity may...

Programmable vs Manual DC Power Supply:Which One Is Right for Your Testing Needs? When choosing a DC power supply for electronics testing, engineers often face an important question: Should you choose a programmable DC power supply or a traditional manual DC power supply? Both types can provide stable DC voltage and current output, but...
