LED display, 200W switching power supply has three sets of outlet, each line with four P10 board. Can bring twelve modules, can I ask a group outlet with twelve boards? What's the difference between dividing into two or three groups? Thank you
Ha ha, seems to be a novice.The switching power supply of 200W is actually 200W, and that number determines how many modules it can take.Each module has a certain power consumption, the power supply can only be 200W, you can figure out how many modules you can bring.Grouping is for assembly, and management is convenient.Several groups also look at the power supply, it is not convenient to see.
The power of general 200W can take 16-20 board if only you can take this module, but if you take system card that one should not take so much, you want to leave the system card card for current margin, because the system not required, but for voltage higher requirements advise system card with 14 module up fast. Of course, in your work you display, multi band module power pressure drop increases, the power of your life will be reduced by 20mA single lamp module you count a module is 32*16*0.02/8=1.28A plus board for their own consumption of 0.5 is 1.78A. You can only use the power rating of 85%, that is, 170W divided by 5V is equal to 36A divided by 1.78, approximately equal to 20 fast modules, which is the maximum ideal value. With 16 dollars is enough, you can only take the line 1.5mm - 12A, is a set of lines you come up with 6 blocks, you can also use the 2.5mm - line can 22A yourself, although the current run very fast but you have to follow the average distribution first, to the actual situation to far, your power line can not be too long, or there will be a drop or close to the power to light, away from the darker. Let's have a look at it.
Standard general power supply with 8 boards, and some power quality is good, you can take a few more, it is best not to exceed 14. Three sets of outlet is interlinked, the power band refers to the number of power supply with the overall, irrespective of the line. A set of outlet can take 12 pieces, other without, but generally do not do so, a few lines to guide a place wiring difficult, inconvenient
Oh, this brother answered too let me dizzy, first of all do not know with what model is used, the high wire, can say in detail, it is not difficult to see that you speak with law for module Oh P10 monochrome, a simple point to say, you use 3 groups then, a group of 3 blocks, each of the current is the same. A group of words, wires increased, the line is reduced, the current is all in one group. Wait a minute. I don't seem to say anything. In fact, it's not scientific to divide this into groups. First, the load is too big, just like you have 130 kilowatts of large equipment. Will you use a big switch to switch it? Do you know how much spark he has on the impact voltage? On the contrary, the upstairs brothers have a point there, but it's not your problem. In fact? You might be thinking of using a line to feel clean and refreshing. The line won't go anywhere. For relatively small current modules, especially walking characters, but some modules are not allowed to do so, because it doesn't make sense.
The three sets of wires are free to use, and how many units can be taken. The main thing is the actual power of the power supply. There is no difference between taking them separately and bringing them together
