Sunbeam Rheobus Extreme Fan Controller
Performance & Testing
As with many of our reviews, we have tested the performance of this product. Unfortunately, the Rheobus Extreme did not seem to be able to provide very accurate voltages on all six channels. As you can see from the test results below, the voltages read from the channels on low ranged from 3.90V all the way up to 4.42V. This is quite a significant range and is definitely a concern of ours. On high the voltages were much more constant with the the voltages only ranging from 11.52V to 11.54V.
Revision note: We should note that the revised version of the Rheobus Extreme has rated voltages ranging from 0V to 12V which allows fans to be completely turned off at the lowest setting. We were unable to do any real-world tests as Sunbeam sent us the original version instead of the revised one.
Voltages
| Low | High | |
|---|---|---|
| Channel 1 | 4.00V | 11.52V |
| Channel 2 | 4.41V | 11.53V |
| Channel 3 | 4.42V | 11.54V |
| Channel 4 | 3.97V | 11.53V |
| Channel 5 | 4.07V | 11.52V |
| Channel 6 | 3.90V | 11.53V |
