We choose power supplies according to the power output. This power is reflected in Amperes (A), the higher the value, the more power the supply will have. To know the equivalent in Watts (w), it is necessary to multiply the amperes by the value of the output voltage of the power supply. In other words, if the supply offers 40A for an output voltage of 5 volts, the power that this supply will offer will be 40A x 5V = 200w. In general, a LED screen power supply must meet a series of requirements:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 5V DC stabilized output<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 110-220V AC input<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 5V DC outputs divided into two or three outputs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 Total power between 200-450W<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 Output amps between 40-60A<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 CE manufacturing certifications<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are many power supply manufacturers for LED screens, although in the last 10 years the technical evolution has been marginal, and most manufacturers share the same components in their power supplies, certain brands have been highlighted thanks to their performance in marketing and promotion.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"alignfull wp-block-ugb-container ugb-container ugb-bc60734 ugb-container--v2 ugb-container--design-plain ugb-main-block ugb--has-custom-content-width ugb-main-block--inner-center ugb--has-block-background\"><style>.ugb-bc60734.ugb-container > .ugb-inner-block{max-width:1440px !important}.ugb-bc60734{padding:0 !important}@media screen and (min-width:768px){.ugb-bc60734.ugb-container{margin-bottom:0px !important;padding-top:50px !important;padding-right:35px !important;padding-left:35px !important}}<\/style><div class=\"ugb-inner-block ugb-inner-block--center\"><div class=\"ugb-block-content\"><div class=\"ugb-container__wrapper ugb-bc60734-wrapper\"><div class=\"ugb-container__side\"><div class=\"ugb-container__content-wrapper ugb-bc60734-content-wrapper\">\n<h2 class=\"wp-block-heading\">POWER SUPPLY TERMINALS<\/h2>\n\n\n\n<div class=\"wp-block-ugb-columns ugb-columns ugb-dbb9993 ugb-columns--design-plain ugb-columns--columns-2 ugb-main-block\"><style>.ugb-dbb9993-content-wrapper > .ugb-column{align-items:center !important}.ugb-dbb9993-content-wrapper > .ugb-column > .ugb-inner-block{height:auto !important}<\/style><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-columns__item ugb-dbb9993-content-wrapper\">\n<div class=\"wp-block-ugb-column ugb-column ugb-ef2d157 ugb-column--design-plain ugb-main-block\"><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-column__item ugb-ef2d157-column-wrapper\"><div class=\"ugb-column__content-wrapper\">\n<p class=\"wp-block-paragraph\"><strong>L (line)<\/strong>: phase terminal or alternating current line at 220V \u2013 110V brown power cable according to Spanish standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>N (neutral)<\/strong>: neutral terminal of alternating current at 220V \u2013 110V blue power cable according to Spanish standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ground<\/strong>: Earth connection of the network.

These losses in power are due to various factors, such as fluctuation of the input voltage, parasites and harmonics on the network, environmental temperature, workload, etc. \u2026 The manufacturers of power supplies usually include an efficiency graph on their technical specifications.<\/p>\n\n\n\n<div class=\"wp-block-ugb-spacer ugb-spacer ugb-7955c04 ugb-spacer--v2 ugb-main-block\"><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-spacer--inner\"><\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-ugb-columns ugb-columns ugb-8464c5e ugb-columns--design-plain ugb-columns--columns-2 ugb-main-block\"><style>.ugb-8464c5e-content-wrapper{grid-column-gap:100px !important}<\/style><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-columns__item ugb-8464c5e-content-wrapper\">\n<div class=\"wp-block-ugb-column ugb-column ugb-2776de4 ugb-column--design-plain ugb-main-block\"><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-column__item ugb-2776de4-column-wrapper\"><div class=\"ugb-column__content-wrapper\">\n<h2 class=\"wp-block-heading\">WHAT IS THE ENERGY EFFICIENCY OF A POWER SUPPLY?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Energy efficiency is the maximum power that a power supply can output, and it is represented with a percentage. Power supplies experience \u201closses\u201d during their operation and fail to output full power for technical reasons. This means that a power supply cannot give 100%. This is where we can see the effects of different qualities in the power supply market: a supply marked as 350w can have an efficiency of 80% and another that is also 350w can have an efficiency of 60%. When making a choice between these two supplies, the one that will offer the best performance will be the one that gives 80%, even if the two mark the same power output.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-ugb-column ugb-column ugb-aa0a0aa ugb-column--design-plain ugb-main-block\"><div class=\"ugb-inner-block\"><div class=\"ugb-block-content\"><div class=\"ugb-column__item ugb-aa0a0aa-column-wrapper\"><div class=\"ugb-column__content-wrapper\">\n<h2 class=\"wp-block-heading\">WHAT IS THE IMPORTANCE OF EFFICIENCY IN A POWER SUPPLY?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Well, this is the most important number to keep in mind when choosing the right power supply. supplies with poor efficiency \u200b\u200bare cheaper, so at first it seems a good option, but when the time comes to calculate the feed for LED modules, we will realize that we need more units than if we had stuck to the more efficient option. This means that using highly efficient supplies improves the consumption of our screens while reducing the interior\u2019s temperature.<\/p>\n<\/div><\/div><\/div><\/div><\/div>\n<\/div><\/div><\/div><\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div>\n\n\n\n<div class=\"alignfull wp-block-ugb-container ugb-container ugb-146afa5 ugb-container--v2 ugb-container--design-basic ugb-main-block ugb--has-custom-content-width ugb-main-block--inner-center ugb--has-block-background\"><style>.ugb-146afa5-wrapper.ugb-container__wrapper{background-color:var(--stk-global-color-45647,#eeeeee) !important}.ugb-146afa5-wrapper.ugb-container__wrapper:before{background-color:var(--stk-global-color-45647,#eeeeee) !important}.ugb-146afa5-content-wrapper > h1,.ugb-146afa5-content-wrapper > h2,.ugb-146afa5-content-wrapper > h3,.ugb-146afa5-content-wrapper > h4,.ugb-146afa5-content-wrapper > h5,.ugb-146afa5-content-wrapper > h6{color:#222222}.ugb-146afa5-content-wrapper > p,.ugb-146afa5-content-wrapper > ol li,.ugb-146afa5-content-wrapper > ul li{color:#222222}.ugb-146afa5.ugb-container > .ugb-inner-block{max-width:1440px !important}.ugb-146afa5{padding:0 !important}@media screen and (min-width:768px){.ugb-146afa5.ugb-container{margin-bottom:0px !important;padding-top:50px !important;padding-right:0px !important;padding-left:0px !important}}<\/style><div class=\"ugb-inner-block ugb-inner-block--center\"><div class=\"ugb-block-content\"><div class=\"ugb-container__wrapper ugb-146afa5-wrapper\"><div class=\"ugb-container__side\"><div class=\"ugb-container__content-wrapper ugb-146afa5-content-wrapper\">\n<h2 class=\"has-text-align-center wp-block-heading\">REFRIGERATION IN THE POWER SUPPLIES<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Power supplies emit heat caused by its components during their operation.
