(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 ...

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 ...
