For test-puposes I needed a dummyload that could withstand 450W on 136kHz for some minutes. Having some 470 Ohm / 25 Watt wirewound resistors in the junkbox I put 9 of them in parallel and measured 5
Building the load into a container of Mineral Oil should increase the power handling quite a bit. I suspect it would make them a continuos load at that power level. Bob On Thu, 18 Nov 1999 18:17:20 R
Rik ON7YD and others, Here in ZL we have been using wire wound resistors as dummy loads for some years, and they generally work well on frequencies up to 180 kHz. Those types with some residual induc
