(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 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.

Leviton has unveiled its next generation electrical Load Center. The new breaker panel works with an integrated Wi-Fi or Ethernet hub to offer remote circuit control, monitor electrical consumption, ...

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 ...
