Like most engineers, I have used dummy loads spanning DC through RF, and from a few watts to hundreds of watts. Most of these loads were built up from basic resistors, and in some cases special ...

We’re not really interested in building a dummy load like this one for ourselves. But the concepts behind its design make for a nice little mental exercise as you read your way through the build ...

Testing DC supplies can be done in many ways, from connecting an actual load like a motor, to using a dummy load in the manner of a big resistor. [Jasper Sikken] is opening up his smart tester for ...

I sold low-power FM transmitters in a former job, and one of the things I learned is that most customers lacked a suitable dummy load for testing. In new LPFM or translator applications, you can save ...

This dummy-load circuit has been in use at Maxim for more than 10 years (see the figure). It's useful for testing power supplies and power amplifiers as well as drivers for LEDs, relays, and solenoids ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

Transmission equipment maker Kintronic Labs will be showing a new line of air-cooled dummy loads at the NAB Show. The power ratings range from 5 kW to 75 kW with peak envelope power expected to be ...

• Calculate the deflections in stepped shafts more quickly and accurately by combining engineering knowledge with mathematics software. • Use Castigliano’s theorem and the Heavyside step function help ...
