How many 16 ft rolls can you put to am 30 watt LED Power Supply which transforms 120 to 12 volts?

My application did not require a power supply (motorhome 12VDC). BUT, the label says it takes 24W. So, the answer is one roll.

I measured 1.25amps for one 5m string of cool whites at 12 volts, so you might just be able to run 2 strings off a 30w supply as that would be 2.5amps. Might need to watch the temperature of the power supply. I opted for a 5amp/60w supply to run 2 strips in my attic installation (since it can get quite hot up there), and if needed I could add a 3rd strip w/o issue with that supply. Not that much more expensive for a few extra amps of supply.

Only one of these strips can be supported using a 30 Watt power supply. We offer several different power options on Amazon and HitLights.com.

72 watts on 12volts doesn't sound unreasonable. A 16.4 foot strip provides plenty of light. I used 8 feet to illuminate my camper van and had to buy a dimmer as it was too bright. My estimation is approximately .25 watt for each diode and there are 18 per foot. Hope this helps. Paul

The power source that came with your LED roll should power up to two LED rolls (16ft each), the repeater will also power up to two (one line coming in and two lines going out (being repeated)). If you need 48ft then you would 3 LED rolls and 1 repeater. 1st LED roll connects to the power source / controller, 2nd roll to the end of the 1st LED and the other end in the repeater IN, third LED roll connects to the repeater OUT. You would still be able to attached a 4th LED roll to the 2nd repeater Out- if you wanted an additional 16ft (64ft total). Hope this helps... good luck!

125 watts 120 volts 15 amps you will need the right screw in socket its the bigger size

You never dim the 120v side of a power supply. Install a led dimmer after the power supply, on the 12v side. Most power supplies are made to output 12v even if the input varies a little. If you want to dim on the 120v side, buy a 120/12 transformer, a full wave bridge rectifier and a capacitor. Match the wattage of the components to what you need.

I have connected one 12 volt 3 meter strip to a 30 amp 12 volt power supply and tested the amp draw to come up with these values. LED Power draw information - - 3 meter set - - 1 - Green only = 1.4 amps @ 12 volts 2 - Red only = 1.39 amps @ 12 volts 3 - Blue only = 1.19 amps @ 12 volts 1+2 - light green = 2.5 amps @ 12 volts 1+3 - light blue = 2.27 amps @ 12 volts 2+3 - purple = 2.28 amps @ 12 volts 1+2+3 - white = 3.18 amps @ 12 volts 3.281 feet in one meter Hope this helps.

Ideally would be 24 watts, without considering conversion losses etc. Being a switching supply, it should be close to the that (basic formula is P=I*E, P is power, I is current, E is volts).

According to the product package one power supply can handle up to 36 watts and each LED strip is only 3 watts so you should be able to connect 12 in sequence without any problems.

i was unable to find LED 120V in that correct size. Maybe later I will install a 12V transformer and then 12v LED

It depends on which LED ribbon strip you are using. The ribbon I have been using is 24watts per 5m, so I can get 6 rolls on it, but not more than 2 5m rolls on a single run.

I have 5 of these, as long as you keep within the 15 amps and under 1775 Watts you will be fine. I run all my LED lights off these, and I have run digital ballast off these, but don't plug a power strip into this with 5 (1000 Watt) digital ballast on the end of the power strip. Hope this helps.

The power supply is 36 watts and 15 volts DC. I also have the plain Finnex Fugeray 48" (no red LEDs) It seems brighter, but is only 24 watts per power supply.

yes , its one roll about 16.4ft with 300leds on the strip, here is the link of the power and connetor , with this , you can light up the strip easyly ,connector __http://www.amazon.com/dp/B014NDTYMY ,12V 5A power_,http://www.amazon.com/dp/B00WIK5OEC

The specifications for the 5Meter LED light strip states each requires 12V and 24 Watts, this means that each 5 meter array draws 2 Amps. The specs also state that each strip must be wired separately not in series, because the internal printed wiring cannot handle more current than each strip requires. This means each strip would require a separate wire running back to the supply if you want to use a single power supply (transformer). If you were going to use a single power source you should select one that will supply the 24 watts for each or the two and a half strips you plan to use. The total would be 24 X 2.5 = 60Watt, to add a safety factor I'd just use a 100W supply and a dimmer of an equal size. The hook up wires can be 24 guage wires, red and black are the standard colors and Amazon sells 50 foot rolls fairly cheaply. One set of wires will be needed from the power supply to the dimmer and then a separate wire from the dimmer to each of the light strips. I have not had any problems with the light strips, I left the lamps rolled up on the spool to increase the heating, ran the strips at 15V to increase the stress even further and let them run for over a month, no failures in any of the sets I've used. I cut the strips to the lengths needed and converted many of the Light in my RV. The power draw for the lights was reduced by two thirds, not bad when your camping on battery power. Well have fun, practice up on your soldering, the contacts are small, but doable, Good Luck, Have Fun

I'd say that was close. I used 1 roll to make 5 light fixtures (for my motorhome), and they each draw just under 1 amp. 6 rolls would get you pretty close to 30 amps.

This is a 30 Watt supply. It is fine for one 16 foot 3528 LED strip (typically consumes about 16W) I have also found that it is OK for one 16 foot 5500 LED strip (typically consumes about 22 Watt). This supply will not run even one 16 foot, high-power LED strip. (I have found that 5630 LED strip (16 foot) can consume as much as 42 Watts - The 5630 LED strip definitely overloads this supply)
