\/><\/figure>\n<p>A &lt;strong&gt;24v 5a power supply&lt;\/strong&gt; is often described as a 120W supply because voltage multiplied by current gives 24V \u00d7 5A = 120W. That number is useful, but it is only the starting point. Real equipment may have startup current, cable voltage drop, heat, and duty-cycle changes that make a simple wattage calculation incomplete.<\/p>\n<p>Start by listing every 24V load. Include LED modules, sensors, relays, controllers, valves, small motors, communication devices, and any indicator lighting. Record normal current and maximum current separately. If the load turns on in groups, note whether several devices start at the same time.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Match_120W_rating_with_margin\"><\/span>Match 120W rating with margin<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure class=\"weho-blog-image\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25.png?quality=85&strip=all\" alt=\"Exact WEHO XLG-120-24 waterproof 24V 5A 120W LED power supply product photo\" title=\"Exact WEHO XLG-120-24 waterproof 24V 5A 120W LED power supply product photo\" width=\"1536\" height=\"1024\" class=\"alignnone size-full wp-image-17548\" loading=\"lazy\" srcset=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25.png?quality=85&strip=all 1536w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25-300x200.png?quality=85&strip=all 300w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25-1024x683.png?quality=85&strip=all 1024w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25-768x512.png?quality=85&strip=all 768w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/03-product-25-18x12.png?quality=85&strip=all 18w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n<p>If a system needs exactly 5A continuously, a 5A supply may be too tight unless the datasheet allows that operating condition at the actual temperature. A safer design normally leaves margin so the supply does not run at its limit for long periods. The margin also helps when line voltage, cabinet temperature, or load current changes.<\/p>\n<p>For outdoor lighting or sealed equipment, choose a case style and power level that match the environment. The <a href=\"https:\/\/www.wehopower.com\/product\/120w-led-driver-ac-95-264v-dc-24v-36v-48v-waterproof-ip67-switching-power-supply\/\">WEHO XLG-120 waterproof 120W LED power supply<\/a> is a relevant 24V 5A product-family reference when the application needs sealed construction rather than an open cabinet supply.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Check_startup_current_and_voltage_drop\"><\/span>Check startup current and voltage drop<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A load that runs at 3A may briefly draw more at startup. Motors, solenoids, LED arrays, and capacitive loads can all behave this way. If the supply enters protection during startup, the system may flash, reset, or fail to start even though the running current looks acceptable.<\/p>\n<p>Voltage drop is another common issue. At 24V, a long cable can reduce the voltage seen by the load. Measure at the farthest load under real operating current. If the voltage is low, improve cable size, shorten the run, split the branches, or choose a supply and layout that fit the wiring plan.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Choose_the_right_enclosure_style\"><\/span>Choose the right enclosure style<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<figure class=\"weho-blog-image\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29.png?quality=85&strip=all\" alt=\"WEHO XLG-120-24 waterproof LED driver detail view showing label cable exits and mounting ears\" title=\"WEHO XLG-120-24 waterproof LED driver detail view showing label cable exits and mounting ears\" width=\"1536\" height=\"1024\" class=\"alignnone size-full wp-image-17550\" loading=\"lazy\" srcset=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29.png?quality=85&strip=all 1536w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29-300x200.png?quality=85&strip=all 300w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29-1024x683.png?quality=85&strip=all 1024w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29-768x512.png?quality=85&strip=all 768w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/04-installation-29-18x12.png?quality=85&strip=all 18w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n<p>Not every 24V 5A application needs the same physical product.

Motors can draw much more than their running current, so check the peak requirement before choosing a 5A supply.\"}},{\"@type\":\"Question\",\"name\":\"How much margin should I add to a 120W load?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Many industrial selections leave 20 to 30 percent margin, then adjust for ambient temperature, enclosure ventilation, startup current, and the exact datasheet derating curve.\"}},{\"@type\":\"Question\",\"name\":\"What cable size should I use for 24V 5A?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Cable size depends on distance, allowable voltage drop, installation temperature, and local practice. For longer runs, calculate voltage drop and measure voltage at the load.\"}},{\"@type\":\"Question\",\"name\":\"What information does WEHO need to recommend a model?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Provide load type, 24V current, peak current, cable distance, installation environment, waterproof or cabinet requirement, ambient temperature, and expected duty cycle.\"}}]}<\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>24v 5a power supply guide covering 120W load sizing, derating, cable voltage drop, startup current, heat, and application checks.<\/p>","protected":false},"author":1,"featured_media":17578,"parent":0,"menu_order":2,"comment_status":"closed","ping_status":"","template":"","format":"standard","meta":{"_acf_changed":false,"_joinchat":[],"footnotes":""},"news_category":[149,148],"class_list":["post-17553","news","type-news","status-publish","format-standard","has-post-thumbnail","hentry","news_category-blog","news_category-industry-news","entry"],"acf":[],"post_mailing_queue_ids":[],"_links":{"self":[{"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/news\/17553","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/news"}],"about":[{"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/types\/news"}],"author":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/comments?post=17553"}],"version-history":[{"count":3,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/news\/17553\/revisions"}],"predecessor-version":[{"id":17581,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/news\/17553\/revisions\/17581"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/media\/17578"}],"wp:attachment":[{"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/media?parent=17553"}],"wp:term":[{"taxonomy":"news_category","embeddable":true,"href":"https:\/\/www.wehopower.com\/vi\/wp-json\/wp\/v2\/news_category?post=17553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
