A guaranteed way to make a receiver or amplifier fail is to create a short circuit by improperly connecting speaker wire to your speakers or receiver. It could be as simple as a stray strand of wire ...

Q. What is the Code rule for sizing short circuit and ground fault protection for a single motor branch circuit? A. The motor branch circuit, short circuit and ground fault protective device must ...

Once an engineer has designed the audio circuit of an amplifier, it would be nice to think that most of their task is complete. However, from a system perspective, that is far from true. At the very ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Circuit breakers now sport advanced features that include remote control and operational status reporting. Engineers have long considered circuit protection a stable if somewhat unglamorous area.

SMPS is the abbreviation of switching mode power supply, a kind of high-frequency power conversion device and a power supply device. Its function is to convert a level of voltage to the voltage or ...

Now that autos are moving toward high-powered battery voltage, the industry is turning new attention toward making sure the flow can stop on a dime when needed. Power management company Eaton Corp.

A German research team has developed a semiconductor-based protection concept tailored to renewable energy systems that forces a permanent short circuit in less than 1 millisecond in the event of a ...
