I have this unit in my RV. The 12 volt lights go from bright to dim repeatedly. Is the converter defective?

Yes, I suspect that is the case, Arlo. The unit I replaced was acting in the same manner. However, it might not hurt to have a qualified tech expert troubleshoot the problem.

I had three 3Watt LED light connected to a 12 Volt DC LED Power Suppply Driver Transformer and the lights keep burning out. Why?

Are you using this for LED tape light? The dimmer is rated for 12 volts. If you hook it up to a power source with a voltage greater than 12 volts the switch may work for awhile, but will eventually get fried.

I had the same issue with the unit i installed. I looked closer at the specs and realized it is a dc 12 volt unit. If you are using an ac transformer, it will not function correct.

Sounds like you are having a heat related problem with the bulb itself. I'd say it's defective. I have no such performance with mine running on 12v marine batteries in my boat.

I would send it back. I have had mine for some time and have had no issues with mine. Sounds like a bad light sensor. Good luck.

This dimmer is for 12 to 24 volts DC. DO NOT wire this to a 110 volt AC circuit. This is used in RV and Marine lighting powered off the batteries. If you are attempting to dim 12volt DC lights on your 110 v system you will need a step down transformer from 110v to 12v. The dimmer goes between the step down transformer and the lights. 12 volts in to the dimmer and 12 volts out that will now dim your lights. Hope this helps?

This is suspect. I would check your volt meter....put a load on the relay and measure it again...its a standard relay and there should be no voltage present. I have encountered mystery power from leads before...but I think its just erronious readings from the meter....are you using a good quality meter? Fluke? Klein? Can you hook a miniature light bulb or LED up to the relay leads and see if there is enough power to activate the bulb? Also how much voltage are you using to power the beam sensor? I used a 12 volt dc power supply with great results. One last thing. Connect your switching device and measure the voltage again. My bet is its gone.... This is suspect.

I doubt it. Better to put a dimmer AFTER the converter block. That is how I run my LED lights, and it works flawlessly *PROVIDED YOU HAVE DIMMABLE LED LIGHTS*. Mine are remote-controlled 16' Cool White CREE strings, and they work flawlessly when dimmed *AFTER* the converter. The power OUT lines are connected to the dimmer unit, and the dimmer unit is connected to the LED string leads. I wouldn't try to put a dimmer on the 120V side, but that's just me.

You would need to step down the voltage to 12v for the lights to work without burning out. I had a problem with several of the lights I purchased in that the 12v in my RV burned and shorted the wires and the panels got so hot that the adhesive pads melted.

I hooked one up to a dimmer switch and it did not work that well. It tends to flicker intensely instead of dimming.

I have not noticed that problem. I still seem to be getting about 6-8 months with mine. I have 7 watt bulbs in 12 volt system, but am running several LED fixtures on this line, so I'm using less than a third of the capacity of the unit. Perhaps you're overloaded? Check the wattage of the bulbs you're running and see if you've got too much wattage overall. I also had a problem when I initially installed it where several bulbs blew. but it turned out to be one of the fixtures I just added. When I removed the fixture, all returned to normal. Must have had a short in it.

Make sure battery is disconnected and rv/trailer is not plugged in to shore power. Remove cover from breaker/fuse pannell. Disconnect Blue, White and Black wire from fuse pannell. Converter unit should slide right out.

Mine do fine until you get to very low levels. Also seems to be sensitive to how quickly you move the dimmer- slower is better for avoiding a flicker.

I would return it if it is not even lighting up. Mine works well with the batteries. It sounds like something might be wrong with the unit. It has to light up to work. Good Luck!but

I have four of those. Same thing happened to one of mine. I recommend a lamp dimmer. Saves energy, and the look is warmer and better in my opinion. I think mine blew cause I had all four of them on one extension cord. But after installing the dimmer I haven't had any more problems.

I would suggest repositioning it in the room, to make sure moving shadows or some other change in light level isn't causing the unit to think it's becoming dark and changing to night mode. Call V-tech support and see what they say, otherwise, yes, I'd agree the unit is defective.
