Cutting battery powered led strip8/13/2023 3) Check and isolate other accessories on the same circuit. Note that the power supply must be powered up for this test. If it shows a voltage less than its rated voltage, you may have a malfunctioning power supply. 2) Confirm that your power supply is working correctly.Ī quick test using a multimeter to verify the voltage across the two output wires, or voltage between the DC plug's inner pin and outer barrel should indicate a voltage differential. Then, check the LED strip itself, which will have its input voltage marked at the LED strip connection points. Check the back of the power supply unit, which will have the output voltage marked. If, for example, your power supply is 12V DC, it will not work with a 24V LED strip. To troubleshoot, try the following steps: 1) Confirm that your power supply's voltage and current rating are compatible with your LED strip. You've connected the power supply to the LED strip, turned the switch on, and.nothing. Use caution and seek the advice of a qualified individual if you are not sure how to perform these tests safely. Note that in some troubleshooting steps we suggest below, you will need to have the power supply plugged in and powered up to complete the test. However, whenever possible, we strongly recommend that you turn off the power to, or unplug, the power supply prior to testing or adjusting any LED strips or accessories. CAUTION: Low voltage DC electronics are generally considered safe and pose a relatively low shock hazard. Through our many years of working with LED strips, we've put together some of the most common causes of LED strip problems and what you can do to solve them. Electrical tape is a good option to secure the connection and insulate any exposed pins should you decide to continue using M/M jumper wire between an inverter and EL wire.LED strips come in a very wide variety of sizes, densities and color quality, but what they all have in common is that at some point, you may run into some difficulty getting them to work. When you are done testing and integrating the EL wire in a project, make sure to seal any exposed EL wire or connections on the AC side. The brightness can depend on the length of EL you are using, how you are wiring the EL, and the type of inverter. While the inverter can light up 4 strands, they are barely visible in normal light and very dim in the dark as well.Īs you can see from the images below, connecting more EL wire in parallel with the 3V inverter will cause both EL wires to dim. At three 3m lengths, you can only tell all three wires are on if the room is dark. When adding a second 3m length, the two get a bit dimmer, but still close to full brightness. Tests with Different Lengths of EL Wire: Some real world testing revealed that this inverter can easily drive a 3m length of EL wire. The mating connector is populated on EL inverters and boards sold in the SparkFun catalog. The end of the EL wire is usually terminated with a polarized 2-pin JST-PH connector (with the exception of the polarized 4-pin chasing EL wire).

On the right is a close up of white EL wire opened up. On the left is a physical diagram of EL wire. Core Wire - At the center of EL wire is another wire.It also separates the corona wires and core. Phosphor Coating - Applying AC power around the coating creates that nice glowing effect from the phosphor being excited.The wire pair is isolated from the center core. These are very fine and can sometimes be referred to as angle wires. Corona Wires - There are two thin wires that wrap around and extend to the end of the EL wire.This sleeve is not as thick as the outer layer and is also clear. Clear PVC Sleeve - A second layer is yet another PVC sleeve.Depending on the manufacturer and color, this may be clear or translucent. Colored, Clear PVC Sleeve - On the outside is a colored PVC sleeve. Let's take a look at the anatomy of standard EL wire. Anatomy of ELĮL consists of a few layers. If you don't reseal, you could end up getting a good jolt. If you do not have an end cap for the EL wire, you can still seal the ends with hot glue or epoxy to seal cut wire. You can cut EL to any length or shape, but you must reseal the ends you cut. Be careful when handling EL products and any exposed circuits that are powered on the AC side. However, it is enough to give you a good shock. With that, it's important to mention that the AC power coming from the inverter is not enough to hurt or kill you. Note: SparkFun does not condone hanging out around high voltage areas.
