Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

This is the first of a two-part series on the processes used to find the short circuit current duties of circuit breakers and fuses. In Part 1, we’ll use a simplified power system to illustrate the ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

Acopian Technical Company has introduced the Low Profile 2 series of switching regulated power supplies designed for use in ...

Understanding the overcurrent trilogy will help you protect your circuits. Circuit overcurrent protection encompasses overload, short-circuit, and ground-fault protection. NEC Art. 100 defines ...

Find a downloadable version of this story in pdf format at the end of the story. Although features and functionality attract the most attention for new electronic products, whether consumer, ...

On the DC side, safety has long been standard – but the AC side of modern PV systems is becoming increasingly complex. The individually engineered AC boxes from Q3 ENERGIE take on a central role in AC ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...
