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 ...

(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 ...

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load.

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” ...

Note: This article is based on the 2002 NEC. Even if you work with stamped drawings, you'll eventually need to do commercial load calculations in the field or on a licensing exam. The National ...

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 ...

More than half of Australian households own an electric water heating system which makes up around 25GWh of daily flexible demand in our electricity network. The majority of these electric water ...
