I'm looking at buying a 300W tubular adjustable resistor. Like this: https://www.digikey.com/product-detail/en/vishay-dale/RBEA03001R000KFB00/541-10193-ND/9765057
Digikey has four part numbers in that RBEA series, 1Ω 25Ω, 50Ω, 100Ω. All of them are 300W, For any of these, how do I know the adjustable range for a given part number?
UPDATE: For background, I want to build a dump load and I would like it to be a little bit flexible, if I can. I'll end up wanting somewhere around 0.5Ω to about 2.0Ω per resistor (I'll probably have four of these in a 2S2P array). It doesn't need to be quick to adjust, and the resistance doesn't have to be dead on. I'll be dumping a max of about 600W and have a plan for a fan and nothing flammable around.
