Re: High power resistor
Hi lerameur,
A resistor that can disipate 1000 watts is called a heater. Seriously... most portable room heaters are 1000-1500 watts.
I doubt that you are going to find a single resistor that can disipate that kind of heat. I have a coil wound cermic heater that is rated at 1000 watts. It gets red hot after about 30 seconds.
How long do you want to dissapate that kind of heat energy??
You may have to go with a switchable array of resistors... say 10 watts X 100 resistors or 200 x 5 watts.
There are solid state (FET I think) loads that have a fan mounted for cooling... like these http://www.westmountainradio.com/cba.php
Buy you are talking a very high voltage... which complicates the matter even more.
good luck
