What Types of Video Wall Processors Can I Choose?

图片
  When considering investing in a  4K video wall , there are some important factors you need to keep in mind. In this guide, we'll take a look at what a video wall is, some of the technology behind it, and the four types of video walls used for different applications ranging from basic to complex. What is a  video wall ? A video wall is a type of multi-display wall that displays a larger image or windows of multiple images by connecting multiple screens together. The display technology can be LCD or LED panels, tiles, cubes or projection screens. A video wall can be as simple as one image from a single source stretched across multiple screens. These types of video walls offer greater flexibility, control, scalability and creativity. ​ Display Screens When planning your video wall, consider what type of display you want to use. You can choose from LED and LCD panels, tiles, cubes and projector systems. Not all displays have the same brightness or resolution, and these spec...

How to Prevent Inverter Clipping

图片
  While oversizing the solar array relative to the   inverter ‘s rating can help your system capture more energy throughout the day, this approach is not without costs.   “Either spend money on an additional inverter or lose energy harvest to inverter clipping.”     When the DC maximum power point (MPP) of the solar array – or the point at which the solar array is generating the most amount of energy – is greater than the inverter’s power rating, the “extra” power generated by the array is “clipped” by the inverter to ensure it’s operating within its capabilities.   The inverter effectively prevents the system from reaching its MPP, capping the power at the inverter’s nameplate power rating.   To prevent this, it’s crucial to model  inverter  clipping to design a system with a DC-to-AC ratio greater than 1, especially in regions that frequently see an irradiance larger than the standard test conditions (STC) irradiance of ...

Do You Know How Inductors Work?

图片
  Inductors , like resistors R and capacitors C, are an important part of passive components that are inevitably used in electronic devices.An inductor is a component in an electrical circuit which stores energy in its magnetic field. It can release this almost instantly. Being able to store and quickly release energy is a very important feature and that’s why we use them in all sorts of circuits. ( Sitong Electronic   has been established for 20 years and our engineers have 40 years of experience.)   Magnetic effect of electric current and coils   An electric current produces a magnetic field and has a magnetic effect on its surroundings. This is the "magnetic effect of electric current", which was discovered by Oster in 1820. It follows that parallel wires with currents flowing in the same direction attract each other, while parallel wires with currents flowing in the opposite direction repel each other. Moreover, Ampere also made a coil of wire into a cylindrical ...

Cree vs COB LED light: Which One to Choose?

图片
  We all know that LEDs last longer, use less energy, and don't produce as much heat as incandescent bulbs. However, there are subcategories of LEDs, such as Cree or   COB LEDs , which offer users the advantages of regular LEDs, so what is the difference when looking at Cree versus COB LED lights?   What is the difference between Cree and COB LED lights? The differences are minimal, but there are enough differences to choose between them.   What is a Cree LED? What is the difference between Cree and COB LED lights? Cree LEDs are simply LED lights that utilize Cree chips. There are many reasons why the lighting community praises the chips used by Cree. However, the most common reasons include high performance output, longevity and stability. You can look at the chips to see if they are Cree. Dual Color 100W IR+White COB LED Cree chips use square chips that are divided into rectangles. cree chips can provide 370 lumens of light to your LED, which is another reason why ...

What is the battery connector called?

图片
  Automotive batteries typically have one of three types of terminals. In recent years, the most common design was the SAE Post, consisting of two lead posts in the shape of truncated cones, positioned on the top of the battery, with slightly different diameters to ensure correct electrical polarity. The "JIS" type is similar to the SAE but smaller, once again positive is larger than negative but both are smaller than their SAE counterparts. Most older Japanese cars were fitted with JIS terminals. General Motors, and other automobile manufacturers, have also begun using side-post  customized battery connector , which consist of two recessed female 3/8" threads (SAE 3/8-16) into which bolts or various battery terminal adapters are to be attached. These side posts are of the same size and do not prevent incorrect polarity connections. L terminals consist of an L-shaped post with a bolt hole through the vertical side. These are used on some European cars, motorcycles, lawn ...

How Should the Laser Lens Be Cleaned and Maintained

图片
In the laser cutting machine optical system, the   laser lens   is a consumable item. In order to reduce the cost of use as much as possible, we should strictly follow this specification to clean the lenses. In the process of cleaning and replacing, laser lenses should be placed, tested and installed with care to avoid making the lenses contaminated or damaged as much as possible. After the installation of new lenses, the protective lenses should be checked regularly and cleaned in time.   Daily preventive measures 1. before dismantling the laser lens, should ensure that the cutting head laser lens window around clean, and not have a fan blowing in the direction of the cutting head, so as not to remove the laser lens when the airflow will bring dust into the cutting head inside, resulting in internal pollution. 2. do not install the laser lens with bare fingers, but wear powder-free finger covers or rubber/latex gloves. 3. should not touch the film layer and mirror when t...
