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 ...

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 ...

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.

Inspired by a design he saw on the EEVblog, [George Graves] put together this constant current dummy load. You might need on of these if you’re testing power supplies or batteries. They pull a ...

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.

When it comes to testing power supplies, it’s useful to have a dummy load to put the gear through its paces. While it’s possible to just use some old heating elements or other big resistors, an active ...
