The base of AEPS-group&#8217;s unit consists of 3 parallel connected AC\/DC modules M1, M2 and M3. This unit can be equipped with <a href=\"https:\/\/www.aeps-group.com\/product\/jetna1000-lp\/\" target=\"_blank\" rel=\"noopener\"><strong>JETNA1000-LP<\/strong><\/a> or <a href=\"https:\/\/www.aeps-group.com\/product\/jetna2000-lp\/\" target=\"_blank\" rel=\"noopener\"><strong>JETNA2000-LP<\/strong><\/a> modules, but if the unit size increases, more powerful <a href=\"https:\/\/www.aeps-group.com\/product\/jetna3000-lp\/\" target=\"_blank\" rel=\"noopener\"><strong>JETNA3000-LP<\/strong><\/a> or brand new <a href=\"https:\/\/www.aeps-group.com\/product\/jetna5000-lp\/\" target=\"_blank\" rel=\"noopener\"><strong>JETNA5000-LP<\/strong><\/a> modules can be added. This increases the maximum power per unit to 15 000 W, and to 60 000 W for four units.<\/p>\n<p style=\"text-align: justify;\">The outputs of the M1-M3 modules are connected in parallel according to a common scheme &#8211; through Schottky diodes to eliminate the influence of failures in the output part of one of the modules on the remaining modules.<\/p>\n<p style=\"text-align: justify;\">Thermal modeling of the design was aimed at developing a small-sized high-efficiency radiator, which provides minimal overheating of the module cases, and a system of fans, which form laminar air flows with uniform distribution within individual air channels.<\/p>\n<p style=\"text-align: justify;\">The system contains all necessary deflectors, overhead chambers and airflow short-circuit blockers for optimization.<\/p>\n<p style=\"text-align: justify;\">Achieved overheating of M1-M3 modules bodies in relation to the ambient air temperature was not more than 20\u00b0C, which ensures that the temperature of the modules bodies is not higher than 80\u00b0C. A distributed-type thermal protection system is used, which activates at case temperatures of 82-87\u00b0C.<\/p>\n<p style=\"text-align: justify;\">Speaking of these remarkable and internationally popular low-profile (planar) AC\/DC modules, it should be noted that they are installed in this unit according to specific customer requirements. These requirements include remote functionality; temperature dependence of output voltage for specific batteries; compliance to MIL-STD-810-F (mechanical), MIL-STD-461F.2007 (EMC) standards; voltage and current monitors; distributed temperature protection and much more.<\/p>\n<p style=\"text-align: justify;\">AC\/DC modules have self-contained EMC input and output filters and fire protection input fuses that cut off the input-side emergency module from the others when it fails.<\/p>\n<p style=\"text-align: justify;\">The modules are non-repairable, have a special thermally conductive rigid polymer casting and encapsulated components for operation in dusty, humid environments and, of course, in conditions of sufficiently large mechanical impacts.<\/p>\n<p style=\"text-align: center;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-11094 size-full\" src=\"https:\/\/www.aeps-group.com\/wp-content\/uploads\/JETA2000-LP.webp\" alt=\"The most popular AC\/DC module on the market JETNA3000 for building centralized converters of matrix power supply systems\" width=\"700\" height=\"350\" srcset=\"https:\/\/www.aeps-group.com\/wp-content\/uploads\/JETA2000-LP.webp 700w, https:\/\/www.aeps-group.com\/wp-content\/uploads\/JETA2000-LP-300x150.webp 300w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/p>\n<p style=\"text-align: center;\"><strong>Fig. 3<\/strong> &#8211; The most popular AC\/DC module on the market JETNA3000 for building centralized converters of matrix power supply systems<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\">Figure 3 shows one of the planar AC\/DC modules from the <strong>AEPS-group<\/strong>. These works of art, created by the engineers of the <strong>Alexander Electric Group<\/strong>, can do a lot of things. But perhaps the most unique thing apart from their planarity (the profile of the whole series is unprecedentedly small &#8211; only 38 mm; you can sink the modules into the body of the radiator for another 6 mm) is the separation of heat flows coming down to the base of the module and in the opposite direction &#8211; up. In this case, optimizing the separation of heat fluxes on the sides of the structure resulted in a result of 87% by 13%. So there is a kind of thermal management (do not remember the foreign name of this process &#8211; I do not like it either).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this, the first article of the series, I present a new custom product&#8230;<\/p>\n","protected":false},"author":14,"featured_media":11155,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[259],"class_list":["post-11090","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-electro-blog","wpautop"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/posts\/11090","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/users\/14"}],"replies":[{"embeddable":true,"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/comments?post=11090"}],"version-history":[{"count":0,"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/posts\/11090\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/media\/11155"}],"wp:attachment":[{"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/media?parent=11090"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.aeps-group.com\/cs\/wp-json\/wp\/v2\/categories?post=11090"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
