Most wire-wound high-power resistors are quite inaccurate. We tested these resistances by sending a constant current of 1.00 A and measuring the DC voltage across the resistors, see the diagram below. The results are excellent, see the attached table. Conclusion: the most accurate power resistors ever bought!

OK. Testata fino a circa 35W. Per potenze superiori meglio montarla su un dissipatore più grande.

Quite small thermal surface to transfer heat to environment. Maximal about 10Watt disappear without additional heatsink or fan. For this price is good choice.

Like the others i think you should not dissipate 100 Watt in to this resistor, you should fix it to a peace of cooling block like aluminum. There are only 2 screws, i would like to see 4 for better conduction and you need thermal grease.

Nice resistors but I did not dare to send 100w through them without some cooling. They measure exactly 8ohm, so nothing to complain about.

Nothing to say, the resistors work well as expected. Only a "particular" thing, the weight is really light than expectation. I've got power resistor of 25W and they have a weight greater than the 100W I bought by Banggood. It could be a light metal body than my old 25W resistor. Tested with 2A DC for 15min, they work well.
