what size transformer

The power supply for this item is a typical "wall wart," roughly cubical in shape with an AC plug attached, and measuring about 2 3/8 by 2 by 1 3/4. Output is 19V. I'm not looking at it right now, but I can get current capacity if you need it.

Determine your ref's wattage and multiply by 3 (just to be safe). Thats your ideal transformer wattage.

Can't answer your question but I can answer a more fundamental one: don't buy this transformer. Mine just burned out after about two weeks of light use.

I switched from the lamps to the LED units and used the old transformer from the initial installation. Obvious much larger than necessary since these LED's are rated at 2 watts. A smaller transformer of 40 watts will work fine with plenty of reserve to add more fixtures.

I'm not familiar with the particular product you mention, but the strips I use are limited to using two 16ft lengths linked together. It would appear that at the very least, you need a larger transformer. The quality of the manufacturer's product often times is also of significance. That being said, I've found these transformers to be amongst the most compatible available.

I connected 2 strips, about 20' on one. You can hook as many strips together as the transformer will allow which is around 3 15' strips for the transformer I have.

I accidentally left the charger that came with the matrix drill plugged in to 220v for a week and surprisingly nothing happened. I will use the transformer from now on. Thanks to CTT for doing the math on what size I should use.

GENERAL RULE: Transformers should not exceed 80% of load capacity. Thus, 160 watts of load for this particular model. You never want to max out capacity. Leave a little breathing room.

6" Long x 2-5/16" Wide x 1-1/4" DeepKeep in mind that these are OEM replacements which can vary a little based on the transformer manufacturer. I have been very happy with these products and have bought 2 of them with no issues whatsoever. They are as good as what Dell and HP sell with their laptops every day. Amazon always backs their products too!

I don't know about any transformer, all I know is I installed it right out of the box and it worked.

10-4. That's what it would be at 75 watts. Divide your voltage into your wattage to come up with the amperage. Primary side (120v) into 75 watts equals .625 amps. OR, 12v on secondary side of transformer, divided into 75 watts equals 6.25 amps. OR, 12v times 6.25 amps equals, 75 watts. I hope that clears it up some. But, either way, this should work as long as whatever it is running, is not over 75 watts, or 6.25 amps.

Well, not that much of an expert but the 1500 is the AMP, Goldsource has various models and the number shows the max AMP that the transformer can take ...Fuse must be pretty standards... Hope this helps

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

A 105W transformer should pull a load of 80W. Normally the range of a 105W transformer is between 35 and 105W. If it is an electronic transformer it should not make noise. Some LED lights cause noises in such transformers. These are the cheaper types.

Hello, Look for the wattage on the transformer and then add up the watts on the bulbs. So a 120 watt transformer can have 12 10 watt bulbs or 2 10 watt bulbs and 25 4 watt bulbs etc

The transformer is 1.5X2.0X5.0 inches and the cords are a little over three feet in length.

it will work but you have to count the number of wires you on your transformer. good luck
