An overvoltage protection of power supply unit is shown in the figure with a regulated 5V output. As the zener diode detects a surpassed voltage beyond its limit, the circuit will get affected in a ...

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 ...

Power protection is like insurance: You pay for it, yet hope you don’t need it. But it’s not a simple “purchase.” The first protection question is, “What am I seeking to protect and against what event ...

Learn what types of circuit-protection technologies are required to overcome metal-oxide-varistor limitations in certain harsh environments to increase application reliability and safety. To ensure ...

Input ratings: Typical power-supply modules are designed and rated to operate with their inputs connected to lines delivering 105 to 125 Vac. Input ratings: Typical power-supply modules are designed ...

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).

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...
