In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together every time ...

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 ...

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 ...

Your remote crew tells you that there is something wrong with their 10 watt 160 MHz RPU transmitter. On site you realize that you need to substitute a dummy load to ascertain if the problem is the ...
