How to connect a led strip?
In order to connect properly led strip you need to know at least a few of its main parameters. It is also important to know the length of the tape, as LEDs are connected and the type of LEDs and possibly the parameters of the current consumption. All you need to know to choose the right PSU for consumption. That he was not the biggest or one of those that will burn in a couple of days of work. Mainly supplied in coil tape five meters long, but not always used in full, often it is cut into pieces and each piece separately zapityvat. Tapes come in both monochrome and polychrome.
first seated you how to connect single color led strip.
first things First you need to look at the current consumption of the entire tape, and the output of the power supply, if the unit can withstand with a small margin, then this is what you need in this case. Sometimes there is a need to connect two or more strips to one power supply, then its capacity must be larger than the combined power of all tapes. Knowing Ohm is law can be sitting at home counting anything:))
do Not buy a power supply if it is on power is identical to the power consumed by the tape, it is important to have some stock on this parameter, so the PSU is not very warm.
By and large the account of connection of the tape is reduced to a pair of manipulation, complicated in procedure no. Is the PSU, there are tapes, just need something to connect everything in the chain and if you need something to break the chain put some kind of control device. This can be a normal switch or a microcontroller with a specific application (on and off - say in the morning to be disabled, and in the evening turn on internal clock is practice in greenhouses or under illumination of the aquarium) . This is the simplest solution.
Take the tape and connected to the power supply, typically on the tape is written where + and where and you actually need to connect the correct polarity. Then at the final stage connected our circuit to 220V. On the PSU there should be written "AC 220V" and "Output Output 12V or 5V, depending on the complexity of the power supply and from his appointment. On terminals "AC 220V" plug cord wire plug under our standard wall outlet. It is worth remembering that there is a certain specificity marking laces and Clem. If you have terminals on the PSU, and they are painted in color, most likely red terminals positive and black negative. But this is not always the case, it is better to take the device and check the polarity and the output voltage, so as to collect all as expected.
When all will gather and turn in the socket, it has to either light up properly or not. If you confused terminals of the power, so to speak filed for an awning power the wrong polarity, the tape just does not light. LEDs do not miss a one way current, but at the same time, are completely open to each other. If not lit, led strip, then you will need to simply reverse the polarity, swap the wires from the power supply and to the led strip. it is pretty simple.
the PSU is your power cord, there is no cord. The main thing to observe according to the passport data and on the power supply and the led strip. Importantly, the same contacts as possible to pack well. If you have the opportunity to solder, if it clips, then you need to watch that the contact was good. If good contact is not, in a place with a bad connection is to be heated, which may result in failure of the entire supply chain.
