(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 ...

Part 1 of this series focuses on high-performance electronic loads for testing power supplies that have low output voltage and high current. It describes the necessity for special electronic loads, ...

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 ...

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 ...
