(Note: Part 1 of this article examined the typical lab setup and powering the circuit under test. Click here to read Part 1.) Most dc/dc power-converter circuits have input capacitors and output ...

Electronic diagnostic module protects against short circuits, reduces downtime. When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 ...

The simplest model of a battery comprises an ideal voltage source that connects in series with a resistance whose value—often a few milliohms—depends on the battery’s electrochemical condition and ...

The new product comes with high-tech features that give residents and property owners unheard-of monitoring and control of the home electrical system. Leviton has introduced a new smart circuit ...

Suitable for use in hazardous and non-hazardous environments, the EC-E circuit breakers selectively protect load circuits connected to a 24-Vdc power supply. The components combine active current ...

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” ...

Let’s take a closer look at the lighting load requirement. The NEC requirements for branch-circuit load calculations are in Art. 220, Part II. These cover three classifications of loads: Lighting ...

The 2026 edition of the National Electrical Code (NEC) now includes 14 AWG Copper-Clad Aluminum (CCA) as an approved conductor for 10-amp branch circuits -- a milestone that expands the acceptance of ...

Leviton has announced a new version of its Load Center breaker box for homes, and it’s adding an integrated Wi-Fi or Ethernet hub that will let you manage your home electrical setup directly from your ...
