Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Article 725 of the National Electrical Code (NEC) covers remote-control, signaling, and power-limited circuits that are not integral to a device or ...

Circuits that fall under the requirements of Art. 725 are remote-control, signaling, and power-limited circuits that aren’t an integral part of a device or appliance. Article 725 includes circuits for ...

The digital control of switching power supplies is firmly established in everything from EV onboard chargers (OBCs) to power-supply units (PSUs) in AI data centers to renewable-energy systems that ...

A ripple-generating circuit is usually needed to ensure stability of constant-on-time (COT) controlled buck converters. Different values of the ripple generating circuit can have direct impacts on ...

Controlling a power supply is a necessary task in many applications, such as in battery chargers, solar power controllers, and so on. Industry provides a rich number of off-the-shelf integrated power ...

A new type of device provides designers of automated installations for North America with performance, cost, and safety benefits. Industrial machinery and equipment system designs typically rely on ...

Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. In response to ...

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 ...

One simulates up to 50× faster than the other, and both will give you comparable accuracy. Which engine would you choose for your power supply circuit? Sounds like a trick question, but it isn’t.

Wherever circuits need protection against current overloads or short circuits, you’ll find circuit breakers. They range from fingernail-sized devices for semiconductor protection to truck-sized ...
