One of the most frustrating challenges for control engineers and specialists is the potential early failure of interposing or interfacing relays used to drive inductive loads. This is especially true ...

[tinfever] needed a high-power benchtop electronic load for an upcoming project, and by their own admission decided foolishly to build their own. And we’re glad they did. The thing is, whilst this isn ...

Diodes Inc.’s ULN2000 series of Darlington arrays integrate seven open-collector Darlington transistors, each capable of producing a 500-mA output current from 50-V outputs. Diodes Inc.’s ULN2000 ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

Increased electrification in vehicles is changing the way driver assistance systems are designed, says Yang Wang, with high-side switches increasingly used for resistive, capacitive and inductive ...

In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...

Aimed at automatic test equipment (ATE), Intepro’s ML1800 is an electronic load with a six-slot chassis that can be specified with up to six 300W or three 600W modules – 1,800W in total. Four modules ...

Typical tests performed with an electronic load involve relatively high currents turned on and/or off rapidly. Either or both of these conditions place significant performance demands, not only on the ...
