I want to use these with a transformer and remove the driver , are these 12 dc or 24dc I have 8 units 3 w ea. so a 30 watt transformer should do it ?

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

I am using 10 - 3watt with a 12/24v transformer and 8 -3 watt with another 12/24 transformer, both running through PCM dimmers. I am using E-Goal 12V 10A 120W DC Switch Power Supply Driver For LED Strip Light Display for both and works great. here is the dimmer 3 of LEDwholesalers LED Strip Lights PWM Dimming Controller For LED Lights or Ribbon, 12 Volt 8/10 Amp, 3301

These are 12VDC and draw about 0.25A at full brightness. A 30W transformer should be sufficient.

Those little transformers are rated for 12volts at 500ma. I'm running four units on one transformer for the past two years, sixteen hours a day with no problem. Hardly warm to the touch. Five units shouldn't be a problem.

Won't it work with a transformer? How high is the wattage? There are two kinds of transformers; one is generally used for up to 50 w. Is this under 50 w?

That is what I use mine on. Add up bulb wattage, should be less than wattage of transformer. I use LED bulbs and can use over a hundred on one 88W transformer, Malibu uses 7W incandescent so 11 or 12 would be the limit.

This unit will definitely provide 24 VDC from a 12 VDC input. I have used several in an application where we needed a 24 VDC supply off of a 12 VDC heavy equipment battery pack. However, charging a battery is typically a more complicated issue - amperage load and not over-charging etc. So you should be good for 24 VDC but I do not know enough in regard to battery charging to say yes or no

If you don't know that, I would advise you not to play with these. Transformer is an AC product only, and 12V + 12V is the RMS rating of each independent winding, assuming that you connect the primaries right, which I remember to be 120V + 120V. The primaries in series will make this transformer to be able to accept 240 VAC, with each secondary at 12V. In this mode, if you connect these primaries in series from 120V, the secondary will only give you 6V+6V. 30VA is the total AC power you can get for the secondary.Be careful and SAFE

Have a look at the back of your power brick (you may need magnifier, I do), it will have an output value saying ___ VDC. If that is 12 or 19 then you should be good to go.

The voltage converter is integrated, so it is not intended for 12V use. If you search Amazon, you will find that there is available a virtually identical-looking 10 watt unit designed for 12V AC/DC. Therefore I would say that it is not worth it to purchase these with the intent to open them up and modify them for 12V use.

Sorry, I have not seen the transformers for previous models. As long as the amperage and the voltage are the same - then you only need the end which plugs into the screw driver to fit and then you are good. I am not quite sure why you would ask this question? Are you trying to use the new charger with old driver units?

Its a 60W max transformer so I wouldn't think there would be a problem with 12 watts.

this transformer puts out 12vac, 600 watts. If you LED lights require this voltage... you're all set.

it depends how many watts you need. If your item needs a power less than 300 or 400 Watt the transformer will be enough

I use a cheap Transformer 230 to 120 Volt, 100 Watt. This was the most bargain Solution.

Not sure, but looks like people had good results with the led wholesalers 30 Watt LED Power supply Driver Transformer 120 to 12 Volt DC Output, 3207

Yes, No problem because 4 x8 watt = 32 watts and this is a 75 watt transformer.
