The National Electrical Code (NEC) requirements for overvoltage protection can be found in Art. 242. This Article is new with the 2020 NEC, and it replaces Art. 280 and Art. 285. Those Articles ...

For amplifier applications which require overvoltage protection and also call for low distortion, low noise, and high bandwidth, engineers must pay careful attention ...

With the 2020 revision of the NEC, Art. 242 replaced two individual Articles that appeared in earlier editions of the Code — Art. 280 [Surge Arrestors] and Art. 285 [Transient Voltage Surge ...

This circuit provides undervoltage and overvoltage protection for dc input supply voltages (see the figure). Its undervoltage cutoff is 6 V, and its overvoltage cutoff is 11.5 V. D3 is included for ...

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 ...

Understanding the advantages, limitations, and use cases of each technology helps engineers create reliable consumer products.
