Input voltage calibration method: After the module is powered on, let the digital display show the input voltage. At this time, the &#8220;IN&#8221; indicator light is always on. Press and hold the button for 2 seconds and then release it. At this time, the digital display flashes. Adjust the calibration value by pressing the button. After adjustment, press and hold the button for 2 seconds to exit the calibration mode and save the set parameters. It will not be lost when power is off;<\/p>\n<p>2. Calibration method for output terminal voltage: After the module is powered on, let the digital tube display the output voltage. At this time, the &#8220;OUT&#8221; indicator light is always on. Press and hold the button for 2 seconds and then release it. At this time, the digital tube flashes. Adjust the calibration value by pressing the button.

The peak output current is 3A, and it should work within 2A for a long time. If it exceeds 2A, it is necessary to strengthen heat dissipation.<\/p>\n<p>3. This module is a voltage reduction module, with an output voltage lower than the input voltage and a voltage difference of at least 1V.<\/p>\n<p>4. The maximum output voltage and maximum output current cannot be met simultaneously, and the maximum output power of 10W is the limiting condition. Output voltage * output current=output power.<\/p>\n<p>5. Do not use load voltage regulation. Adjust the parameters first, then connect the load circuit, and finally connect the power.<\/p>\n<p>6. Do not use high voltage, high current, or hot swapping to prevent damage to the module.<\/p>\n<p>When the input voltage is below 4V, the digital display will not display or work. To ensure the accuracy of the voltmeter display, the input voltage must be above 4.5V.<\/p>\n<p><img decoding=\"async\" data-no-lazy=\"1\" loading=\"lazy\" src=\"https:\/\/www.diyipcb.com\/wp-content\/uploads\/module-store-import\/2025\/description_images\/renamed_description_images_filtered\/lm2596dcdc_1.jpg\" \/><img decoding=\"async\" data-no-lazy=\"1\" loading=\"lazy\" src=\"https:\/\/www.diyipcb.com\/wp-content\/uploads\/module-store-import\/2025\/description_images\/renamed_description_images_filtered\/lm2596dcdc_2.jpg\" \/><img decoding=\"async\" data-no-lazy=\"1\" loading=\"lazy\" src=\"https:\/\/www.diyipcb.com\/wp-content\/uploads\/module-store-import\/2025\/description_images\/renamed_description_images_filtered\/lm2596dcdc_3.jpg\" \/><img decoding=\"async\" data-no-lazy=\"1\" loading=\"lazy\" src=\"https:\/\/www.diyipcb.com\/wp-content\/uploads\/module-store-import\/2025\/description_images\/renamed_description_images_filtered\/lm2596dcdc_4.jpg\" \/><img decoding=\"async\" data-no-lazy=\"1\" loading=\"lazy\" src=\"https:\/\/www.diyipcb.com\/wp-content\/uploads\/module-store-import\/2025\/description_images\/renamed_description_images_filtered\/lm2596dcdc_5.jpg\" \/><\/p>\n<div class=\"simg-pop-btn\" style=\"top: 1914.22px; left: 14px; display: none;\" data-hover=\"0\"><\/div>\n<div class=\"simg-pop-btn\" style=\"top: 2720.44px; left: 14px; display: none;\"><\/div>\n<div class=\"simg-pop-btn\" style=\"top: 4332.89px; left: 14px; display: none;\"><\/div>\n<section class=\"module-customization\">\n<h3>Personalizaci\u00f3n de productos<\/h3>\n<p>Ofrecemos servicios de personalizaci\u00f3n de productos. <a href=\"https:\/\/www.diyipcb.com\/es\/contact-us\/\">Cont\u00e1ctanos<\/a> para hablar de sus necesidades.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"<p>Voltage regulator chip: LM2596S-DJ Equipped with reverse connection protection, overheating protection, and short circuit protection Input voltage: DC4.0-40V Output voltage: DC1.25-37V continuously adjustable Output current: maximum 3A Output power: Maximum 10W (5V\/2A) Trinity 0.36-inch red digital tube Equipped with an input\/output voltage indicator light that can be switched by pressing a button to display the&#8230;<\/p>","protected":false},"featured_media":5279,"comment_status":"open","ping_status":"closed","template":"","meta":{"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":""},"product_brand":[],"product_cat":[99,94,2098],"product_tag":[],"class_list":["post-9197","product","type-product","status-publish","has-post-thumbnail","product_cat-displays-hmi","product_cat-electronic-modules","product_cat-prototyping","first","instock","shipping-taxable","purchasable","product-type-simple","entry","content-bg","loop-entry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product\/9197","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/comments?post=9197"}],"version-history":[{"count":0,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product\/9197\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/media\/5279"}],"wp:attachment":[{"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/media?parent=9197"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product_brand?post=9197"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product_cat?post=9197"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.diyipcb.com\/es\/wp-json\/wp\/v2\/product_tag?post=9197"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
