    Perfect for project
  

*by M***E on Reviewed in the United States on 25 June 2024*

I purchased this item for a mod project on my Maxxair Fan on my Hiker Trailer teardrop camper. You can find numerous YouTube videos on how to do it, if you need to.The size and ease of install could not be easier (well, for me at least, and there is plenty or room within the fan's housing to place it easily ).Time will tell how long it will last but I anticipate it will do what it's supposed to do for a very long time. I tested everything after install and the voltage to the fan's CB remained a steady 12v.EDIT: 10SEP24...went camping and turned MaxxFan on, no dice....troubleshooting revealed that that no voltage flowed through regulator....it failed.....I withdraw my recommendation.

    Voltage stabilizer for MaxxFan issues
  

*by K***O on Reviewed in Canada on 6 February 2024*

This DROK DC Stabilizer is one of 2 main fixes for the dreaded MaxxFan green light beep and failure. The MaxxFan is the Best and Worst RV fan in the industry. When working, it is without a doubt the best RV fan with the most air movement, quietest operation, and low amp draw of the various options out there. But it suffers from 2 manufacturing fatal flaws that have been well documented by many who have suffered the fan failure. The first flaw is the circuit board not being waterproof, and living below a vent cap that can allow outside water onto the board, or inside condensation to drip onto the board. The second flaw is the electronic components used that are extremely sensitive to voltages over 13 volts or so. This is problematic as many RVs see voltages up to 14 to 14.5 volts when receiving charge from a generator, a tow vehicle, or a solar system. So having read numerous accounts of fan failures, and methods to correct the problem, I went in search of a DC voltage regulator. This one received good reviews, was well priced, and was also used by other fixing the same issue with their own MaxxFans. I installed this voltage regulator after having to replace my failed circuit board, in the hope that this permanently solves one of the problems. I bench tested this unit before installing it, as shown in the photo, using a portable lithium battery that provided 13.3 volts output. This Autoutlet regulator held the through voltage to a constant 12.2 volts. After installation, I again tested it once connected to my RV 12 volt system, which on shore power with the  battery charger active was showing over 13 volts. This regulator did a great job of holding it to 12.2 volts installed. To protect the circuit board from problem #1 (moisture) I also coated top and bottom with thin coat of GE Silicone Supreme (neutral curing silicone sealant). I'm hoping these two remedies will keep my MaxxFan operating for many more years to come, hopefully with no more flashing-green-lights-of-death.  I can't speak to longevity of this voltage regulator yet as it's only been in for a few months of operation, but so far it has helped the fan work flawlessly, thru all 10 speeds, in forward and reverse, as it is meant to operate. If you're looking for a reliable Voltage regulation option, I can highly recommend this Autoutlet device and the company selling it. Check out the attached photos for visuals of how I mounted it, using hot melt glue, into the outer frame of the fan. This caused no problems with clearance even in the low profile roof of our little Coachmen Apex Nano trailer.

El funcionamiento es adecuado, lo utilicé para eliminar el efecto de parpadeo de luces para una motocicleta y funcionó perfecto al rectificar los 12v requeridos
