While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a ...

This constant resistance dummy load has not yet been tested in the real world. [YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant ...

Testing bench power supplies would require the use of a current build and the best way to have one is to build yourself one. The article shows how a custom dummy load is built. Testing bench power ...

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 ...

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 ...

Kintronic Laboratories doesn’t mind that dummy loads have long been the butt of engineer jokes. They’ll keep developing new ones. For the 2011 NAB Show, two new ones will be in the Kintronic booth.

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 ...
