    Surge voltage is a common but potentially serious damage phenomenon in electrical equipment and systems. To protect these devices, engineers typically use metal oxide varistors (MOVs) and surge protection devices (SPDs). Although both are used to protect against surge voltage, there are significant differences in their working principles, structures, and application scenarios. This article will explore in detail the differences between MOV and surge protection, and explain their applications in light control products. Working Principle MOV (Metal Oxide Varistor): MOV is a varistor whose resistance value adjusts rapidly with changes in voltage. When a surge voltage appears in the circuit, the resistance of the MOV decreases rapidly, shunting the overvoltage […]<\/p>\n","protected":false},"author":1,"featured_media":2677,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_robots_primary_cat":"none","_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","footnotes":""},"categories":[1,185,184],"tags":[],"class_list":["post-2669","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","category-knowledge","category-news"],"_links":{"self":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/2669","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/comments?post=2669"}],"version-history":[{"count":1,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/2669\/revisions"}],"predecessor-version":[{"id":2676,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/posts\/2669\/revisions\/2676"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/media\/2677"}],"wp:attachment":[{"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/media?parent=2669"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/categories?post=2669"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/leaditop.com\/ja\/wp-json\/wp\/v2\/tags?post=2669"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
