What Do You Need to Pay Attention to When Applying ETL Authentication AC Light Source Module

There are different test standards in each industry. Among the electrical and photoelectric products, the ETL inspection sign indicates that it is tested that it meets the relevant industry standards that meet the relevant industry standards. The ETL inspection logo is widely used in photoelectric products. With the development of the economy, there are more and more related applications involving the ETL authentication AC light source module. But when we apply ETL authentication AC light source module, it will cause problems. So what should we pay attention to? At present, as the LED display is widely used, consumers usually require manufacturers to help installation when buying LED display. Although for sophisticated technicians, the LED display installation can be described as light cars, but for some technicians who have just touched the LED display, it is often easy to ignore some places when installing the LED display, which leads to unnecessary unnecessary unnecessary. There was a problem. 1. The input method used by ETL authentication AC light source modules is low pressure, so you must not enter 220V directly, otherwise the entire module will be damaged, which will cause unnecessary losses. 2. When installing the ETL authentication AC light source module, it is required to use double -sided or woodworking glue to make the module card slot and the plastic base plate firmly paste. When using double -sided glue, you must add glass glue, otherwise it will cause the module to fall off under long -term exposure of the outdoor sunlight. This is quite important. 3. When installing an ETL authentication AC light source module in the sucking word or the box, try to use three points and quarter lines as much as possible to form a loop or multiple circuits in the entire word or the box when connecting. Red and black power cords connect the modules at the end of each stroke according to the positive and negative electrode. When the power cord is connected to the box, it must be connected to the corresponding four or three sets of modules through a quarterly line or a three -point line first. After the power cord enters the box, a large knot should be played to prevent ETL authentication AC light source module. 4. Adjust the output voltage of the ETL authentication AC light source module according to the actual situation. When the module is used in the use process, it cannot adjust the voltage at will, otherwise it will cause an impact. 5. Install the ETL authentication AC light source module without waterproof treatment. Pay attention to whether there are water entering. Moreover. 6. When installing the ETL authentication AC light source module, it should not be too hard to avoid destruction of the device and affect the overall effect. 7. ETL authentication AC light source module has a positive and negative pole. Pay attention to whether the power port wiring is positive and negative during installation. If the positive and negative is the opposite, then the module will not glow. But dont worry, it will not damage the module when it is connected. Just take it back to the normal direction. 8. ETL authentication AC light source module spacing can be adjusted according to the requirements of the brightness. Each square meter cloth is generally controlled between 50 and 100 groups. 9. The number of connected groups in the power port is recommended not to exceed 50 groups, otherwise the tail module will cause the ETL authentication AC light source module due to voltage attenuation. Although this phenomenon can be weakened through the method of circuit, it is not recommended to connect too many modules. 10. Generally, when connecting the ETL authentication AC light source module, the wires are firmly inserted, so as not to cause future falling off. In order to prevent the occurrence of falling off in the future, it is usually refueling on the online design. If the connection is inconvenient, you can exit and re -insert.
