Look at the example schematic that Bill Marsden posted. LED strip splitters make it possible to plug multiple strips into one power supply with ease! Strip splitters are available with 2, 3 or 4 output channels. Connecting multiple 12V LED lights to one power source? Measuring LED strip current. In short, wiring in series divides the total power supply between the LEDs. One string starts with R1 at the top and one string has R2 at the top. If using a digital multimeter then be sure to plug the red lead into the 10 A socket, and switch to 10 A range before powering up. Each LED strip had to be wired separately with it's own DRIVER/CONTROLLER. The total amps will be the sum of all the individual amps readings. If you're trying to connect more than one LED strip segment to a single power supply, you may suddenly realize that you could connect the first segment to the second segment in "series" or connect to two segments independently to the same power … LED strip lights are typically dimmed with in-line pulse width modulation dimmers. Whichever method you choose, make sure you cut your light strip along the designated cut points to ensure your lights will work if necessary. Also, this will likely cause you to need to run supplementary power wire to connect to any strip beyond 2. If you want to connect more than two regular RGB LED strips through a single controller, you MUST to get a higher wattage/amperage one. Converting to watts Step 2: Connecting the LED strips. How to control multiple strips / areas of LED strip lights? So from there I'd create interconnects to wire up each of the frames to the power source. I do not know very much about electricity, but I do know how to solder and do the mechanical portion of this problem. Should LED strip sections be connected in "parallel" or "series"? The problem however is that the remote can get out of sync with the lights strips and then it's pure h^ll trying to get them all back in sync, only to … Dimming LED Strip Lights. I used 3.0V for Vf as an example. We don’t carry them as a normal stock item, but are able to help with special orders. Only one remote will operate all 4 strips. To connect your LED strip lights, you can either use a connector for easy attachment, or you can solder the wires to the strip, which carries more current and creates a more stable connection. Hook up a multimeter as shown in Figure 2. and measure the current drawn by one strip. The schematic on the right has two strings of LED's in parallel. We could take those same four 3V LEDs and wire them in parallel to a smaller power supply, say two AA batteries putting out a total of 3V and each of the LEDs would get the 3V they need. If you have a project, such as a home / restaurant or bar, where you have several areas of LED strips, then you may want to control them independently or synchronised together. - Wireless RF options. I have multiple (4) 12 volt LED light strips with a positive and negative wire. Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply. The expensive way would be to connect a high capacity power source in parallel to multiple LED controllers and their associated LED strips. All you need to do is to identify the anode (positive) and the cathode (negative) ends of each LED strip. Check out our new vlog. ... or two different runs but still to the one power supply. The picture on the left has only one LED and one resistor. Your LED's are probably different. How to connect multiple LED strips to one power source? Figure 2. Learning how to connect multiple LED strips to one power source shouldn’t necessarily jade you if you opt for the series circuit.
