acegoo 12V Dimmer Switch Aluminum RV Light Dimmer High-Side PWM Dimmer, Perfect for Camper Van Boat Trailer Truck Cars, Works with 12V LED Light Fixture, Rotary Dimming (6A-Upgrade)

Nice PWM dimmer. The switch is a nice feature. The dimmer brightness is not very linear, but works well and has a nice smooth feel to it.

Dimmer arrived in excellent condition and is well built with the aluminum plate. Easily wired and installed in our RV trailer. I added new 2.75” recessed lights with the dimmer. My wife loves the new lighting system, so my life is much happier when camping! I would highly recommend this dimmer and I purchased a second unit for bathroom lighting. 😊

I think it works as advertised. Hope it lasts for a while...!

Installed easily as I had a ground in the panel where I was installing the switch.I had hoped to use without the aluminum cover plate in a plastic monitor panel but after install I felt the switch was getting too warm.So I moved to a location that allowed me to use the faceplate but isn’t as convenient a location.I’m only loading this 6amp version with 3.1 amps so I was surprised how warm the switch gets.The lights however dim well. As others noted this switch makes the lights flicker a little as you are adjusting the knob but they do not flicker otherwise.

This dimmer switch is definitely well built and sturdy, but we must have gotten a defective switch. There is no option to contact the seller on amazon or return it as it's past it's date. We are doing an RV build and finally putting it in over a month after buying. The dimmer switch will turn the lights on and off but the dimming feature does not work at all for us. We bought the dimmable puck lights from the same brand that seem to be good quality. We even took it down and rewired it again following their instructions each time but the dimming feature does not work.

This can vary the output voltage from 6V - 13V on a 13V DC supply or battery as the source with no load. If you give it 24V input then you can go up to those levels.Oddly, it doesn't seem to regulated the output voltage and is greatly affected by a load.For example, when set to 10V DC output if you add a 4 ohm load (which would be a 2.5A load) the output drops way down to 6V and is no longer at 10V DC.However, you could manually force it back into range by compensating with the dial but it's odd that it doesn't try to regulate at all.This won't really work for what I was trying to do since the output voltage doesn't seem to run proportional with the dial position. It's affected by load as much as dial position in a simply resistive circuit.On the plus side, I didn't push it up to the max listed of 6A but it handles a 3Amp load at 12V and didn't generate much heat in doing so.

I used this in my travel trailer so that I could dim down the light over the dining table. I removed the plate, drilled a hole in the hood of the light and can now control brightness easily. I’d buy this switch again.

Bought the 6A Rotary version. Wired them up and they worked as expected. However after 24 hours of not even being used, one stopped working past the dimmest setting. Additionally, the both stayed warm even when shut off completely. Not sure why they were defective but I'll be looking for alternatives to these because the dimming functionality in a camper is very nice.
