Hot-swap circuits are among those measures put in place to protect equipment or personnel, or both. Some power supplies, for example, have built-in and adjustable current limiting (standard in ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...

Not that this happens often, but what do you do when faced with a repair where you don’t know the power source but you do know you have to drive LED backlighting? When faced with this dilemma [Eric ...

Designed and dual-rated for AC and DC applications, the Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer protection for application with up to ...

A previous Idea for Design described a technique for protecting the “pass” transistor in a current-limiting circuit against excessive power dissipation (see “Fault-Protected Current Limiter Keeps Its ...

One of the major challenges facing the electric industry is how to manage network fault levels, the magnitude of the electrical current that flows into a fault or short circuit. These current levels ...

The circuit protection market is filled with such a wide variety of fuses today that the previously accepted method of specifying fuses is just not enough. Instead, the proper application of fuses in ...

Per 2014 NEC Article 100, short circuit current rating (SCCR) is defined as: “The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected ...
