I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

Important specifications and concepts must be considered to protect low-voltage subsystems in consumer applications, including the use of input and output capacitors, thermal performance, and ...

In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

This Design Idea presents a low power short circuit finder that capitalizes on the ear’s sensitivity to changes in frequency. The heart of the circuit is a voltage-to-frequency converter (based on ...

Edison was right; direct current is better than alternating current. Tesla and Westinghouse won the current wars, because it was easy to transform into different voltages without electronics, and they ...
