To ensure reliability and safety for devices that run on ac and dc power lines, circuit protection is a definite design requirement. Unfortunately, there’s no universal protection solution. Varying ...

At one time, the National Electrical Code (NEC) contained two Articles you won’t find as of the 2020 revision: Art. 280 (surge arrestors) and Art. 285 (transient voltage surge suppressors or TVSS).

Although microcontrollers generally run at low voltages, such as 3.3 V, they often need to control loads running at higher voltages like 12 V. If switching the low side isn’t an option, the ...

This 8V DC power supply was designed for use with an expensive piece of electronic equipment. It features full over-voltage protection as a precaution against regulator failure, either in the supply ...

A Zener diode can be used as an overvoltage protector that shunts fault current through ground via a current-limiting resistor (Figure 2). Note that the Zener protection is effective only if the Zener ...
