How many volts is the main card power supply of the outdoor LED display

The display controls how many volts are snapped into.

Whether the power supply of the small LED display can be directly powered by a 6V battery also depends on how many volts the power supply voltage it requires.

Generally, the working voltage of small LED display is 12V or above, of course, if the display screen itself requires a power supply voltage of 6V, it can be directly connected and used. If the display voltage is not 6V, you can't directly use 6V power supply, you can choose a DC-DC converter to raise the 6V battery voltage to the corresponding voltage, and then drive the display.

Now there are many DC-DC varieties on the market, which can be purchased according to the actual voltage and current of the display screen.

The upstairs are all P10, what if you don't use P10.

I'll tell you a way to calculate the power of the board.

Generally, you take a lamp bead to calculate, a board of total lamp beads *, if the board is 4 sweeps with 4, 8 sweeps of 8, static does not remove.

This gives you the power of a board.

The power of the power supply The power of a single board is the number of plates that can be carried, I hope it can help you.

Mine has 14 P10 strips, power supply* (The power of each unit board can be rounded down.

This is what the person who sells you when you buy a power supply will tell you that it's generally 10 pieces and a good 12 pieces.

The display screen needs to use a computer serial port to communicate, because notebooks generally do not have a serial port, you need to find a specific genus.

The outdoor LED display is connected to the power supply and the indoor LED display is connected to the power supply in the same way.

Generally, the display screen uses five volts of electricity. Connect the 5-volt output on the 5-volt power supply to the module....220V can be connected to industrial electricity.

You have to ask the manufacturer what the front letter represents, and different manufacturers will use different letters to identify; 200 should mean that the power of the power supply is 200 watts, and 5 should mean that the output voltage of the power supply is 5V, and the power supply voltage used on the display screen is not high. The current is very large. Like this 200W5V power supply, the current is 40A.

A = Amps. 200=200W should be a power supply of 5V40A-200W.

The letters represent the series of products, and 200 represents 200w. 5 means power 5V.

The letters represent the serial model of the product, 200 indicates the power, and 5 indicates the voltage.

Please connect the positive and negative poles of the receiving card directly to the power supply, you have already had a voltage drop when you connect the module like that, and then connect the receiving card even more.

It is best to divide the power cord from the middle to both sides, and one cable can carry up to 3 modules.

It's best to go straight from the power supply to the control card, so that the current to the control card will become very small.

In general, the control card should have a separate power supply, which is better for the control card. This roadmap of yours is not very good.

I don't know much about this kind of engineering drawing, but you can check it if you have any questions - Huahai Tech's **, is a professional LED manufacturer, I believe it can help you!

The display comes to the inlet termination and is enough to control the self.

To make a control card for points, install the driver on the computer and use the control card to control the display!

The specific method of connecting the LED display to the computer is as follows:

1. Black screenDuring the use of LED outdoor screens, if there is a black screen, first check whether the display is powered on and whether the data cable interface is loose or falling off. After making sure that these are correct, check that the software is working properly. If the software is also displayed normally, it is likely that there is a damage in the middle of the data cable or a problem with the sending and receiving cards.

2. The display position is incorrect, and this situation is mostly a problem with software settings. In particular, the control computer changes the resolution so that the corresponding picture is mapped to other positions, resulting in a display misalignment.

3. Other problems such as blurred screens, partial displays, etc. There are many cases of synchronous display problems between LED displays and computer monitors, and the reasons are more complex.

BAI's wiring.

1.First of all, the cut DU profile is spliced, and the outer frame of the display DAO is assembled. The market-specific general profiles are all square and round, but the assembly method is the same.

2.After assembling the outer frame, place the P10 unit board in the frame (pay attention to the front and back sides of the frame, the slotted side is the front), and the position of the mounting back strip is quite accurate, so as to avoid the trouble of changing all the wrong one.

3.After the back strip is fixed, remove the frame and install the magnet, as shown in the picture below

4.Secure the unit board.

5.Connect the cables and the upper and lower power cables.

6.Fix the display power supply and the LED control card, and connect the LED control card with the power cable. Connect the LED control card with the power cord to the nearest unit board, and the positive and negative poles are marked on the control card.

7.The display power supply is wired with the display unit board, pay attention to the positive and negative poles, it is recommended to use SVV2* soft core wire, that is, the main power supply of 1 square double-strand soft core wire is selected according to the size of the screen.

8.The control card is connected with the unit board cable (especially important), please read carefully before connecting, the screen is not fixed on the wall, this is the most critical step, you can check whether the screen is installed correctly through the test button.

9.Data cable (short distance generally with super 5 category network cable can be) normal generally use serial port cross line, there are also parallel lines, software CD-ROM generally have wiring instructions.

1. Use a microcomputer timing switch, connected to the AC contactor of the electronic screen, set according to the time when you turn on the computer every working day, the timer is set to be a few minutes later than the computer, and the closing setting is a few minutes earlier than the computer. Although the light board now has a protection circuit, it is better to form a habit. Turn on the computer first and then turn on the screen, and turn it off in reverse.

2. If there is a setting in the software setting of the LED studio, it is in the automatic setting. Note that the format path of the file should be correct, or the file cannot be found when the software starts automatically.

LED lights use a switching power supply, and the common power supply does not have a signal control function!

1. Purchase a power timer separately.

2. Change the power supply with signal control function.

3. Modify the power supply by yourself.

How much power is the current power supply?

Also, if you look at the client control software, there is a "screen power control" option, which is usually available.

Hehe, I have encountered this problem in my previous projects, and then it was solved like this:

An IO is drawn from the CPU to control a triode, and the transistor controls a relay, and then the relay controls a contactor, and the contactor controls the power supply of all LED parts.

In this way, the PC sends instructions to the single-chip microcomputer, and the single-chip microcomputer turns off the power supply of the LED part, leaving only the power supply of the CPU itself still on, but the power is not even 5W, hehe.

In the morning, the PC sent an order again, and the single-chip microcomputer connected the power supply of the LED part again. At this time, in order to minimize the inrush current, the CPU should constantly clear the screen, that is, make the LED completely black, and reduce the load of the power supply.

The sound of the contactor closing is still quite loud, so be prepared, but it doesn't matter if your screen is outside.

That's what you need, hehe.

Add a timer switch on it, and the switch time is set by yourself, which is very commonly used.

As for the LED studio auto-start, open the studio, Settings - Software Settings - Auto Settings - Start when starting Windows - Automatically load files on startup, tick, save the settings, and that's it.

It is equipped with a multi-function card that can transmit sound and remotely control power-up.

The LED software can turn off the setting, which is the timing command table. However, it is best to add a power controller to the main power supply.
