The DC SPD finds voltage jumps on either line and sends extra energy away from important parts. The main part, the Metal Oxide Varistor (MOV), changes how much it resists current during a surge. This lets surge current go through the MOV and protects your system. Your SPD also has a tripping part and a device that disconnects. These break the current path and stop arcs, which is important because DC systems do not have zero-crossings. You get more safety and can see problems with remote signals and arc isolation.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>DC SPDs can fail in two main ways during surges: open-circuit and short-circuit failures. Open-circuit failures happen when the SPD stops working because its disconnectors turn on, often without you knowing, which can leave your system unprotected. Short-circuit failures can happen from long high voltage or faults, and may cause fires. To help, DC SPDs use disconnectors inside, thermal protection, follow IEC rules, and use extra overcurrent devices outside.<\/p>\n<\/blockquote>\n\n\n\n<p>\ub2e4\uc74c\uacfc \uac19\uc740 \uc548\uc804 \ubd80\ud488\uc774\uc788\ub294 DC SPD\ub97c \uc120\ud0dd\ud574\uc57c\ud569\ub2c8\ub2e4. <a target=\"_blank\" href=\"https:\/\/cnkuangya.com\/ko\/%eb%b8%94%eb%a1%9c%ea%b7%b8\/%ed%9a%8c%eb%a1%9c-%eb%b3%b4%ed%98%b8%ec%97%90%ec%84%9c-%ec%84%9c%ec%a7%80-%eb%b3%b4%ed%98%b8-%ec%9e%a5%ec%b9%98-spd-%eb%b0%8f-%ed%93%a8%ec%a6%88-%eb%b6%84%ec%84%9d-%eb%b0%a9%eb%b2%95\/\">\uc704\ud5d8\ud55c \uc2e4\ud328<\/a> \uc2dc\uc2a4\ud15c\uc744 \uc548\uc804\ud558\uac8c \ubcf4\ud638\ud558\uc138\uc694.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\uc11c\uc9c0 \ubcf4\ud638 \uc7a5\uce58 \uad6c\uc131 \uc694\uc18c<\/h2>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6.webp\" alt=\"\uc11c\uc9c0 \ubcf4\ud638 \uc7a5\uce58 \uad6c\uc131 \uc694\uc18c\" class=\"wp-image-2022\" srcset=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6.webp 1200w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6-300x169.webp 300w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6-1024x576.webp 1024w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6-768x432.webp 768w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6-18x10.webp 18w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2025\/10\/556330d0b72a45ae8762e727494be7a6-600x338.webp 600w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">\uc774\ubbf8\uc9c0 \ucd9c\ucc98: <a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/unsplash.com\">\uc5b8\uc2a4\ud50c\ub798\uc2dc<\/a><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">MOV<\/h3>\n\n\n\n<p>Metal Oxide Varistors, or MOVs, are the main part of your <a href=\"https:\/\/cnkuangya.com\/ko\/%eb%b8%94%eb%a1%9c%ea%b7%b8\/%ed%9a%8c%eb%a1%9c-%eb%b3%b4%ed%98%b8%ec%97%90%ec%84%9c-%ec%84%9c%ec%a7%80-%eb%b3%b4%ed%98%b8-%ec%9e%a5%ec%b9%98-spd-%eb%b0%8f-%ed%93%a8%ec%a6%88-%eb%b6%84%ec%84%9d-%eb%b0%a9%eb%b2%95\/\" target=\"_blank\">\uc11c\uc9c0 \ubcf4\ud638 \uc7a5\uce58<\/a>.

These diodes work almost right away when voltage jumps. Their quick action stops damage to your equipment. Suppression diodes clamp and limit voltage by working in a special way. You see them as the last part in circuits with many levels. TVS diodes, a special kind, work faster than spark gaps or GDTs. This speed is important for protecting sensitive electronics.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\ucc38\uace0: \ub2e4\uc774\uc624\ub4dc\ub294 MOV \ubc0f GDT\uc640 \uc798 \uc791\ub3d9\ud569\ub2c8\ub2e4. \uc774 \ubaa8\ub4e0 \ubd80\ud488\uc744 \ud568\uaed8 \uc0ac\uc6a9\ud558\uba74 \uc11c\uc9c0\ub85c\ubd80\ud130 \ub354 \uc798 \ubcf4\ud638\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n<\/blockquote>\n\n\n\n<p>\uc2dc\uc2a4\ud15c\uc5d0 \ub9de\ub294 \uc11c\uc9c0 \uc7a5\uce58\ub97c \ub9cc\ub4e4\uae30 \uc704\ud574 MOV, GDT, \ub2e4\uc774\uc624\ub4dc\ub97c \uc801\uc808\ud788 \uc870\ud569\ud558\uc5ec \uc120\ud0dd\ud569\ub2c8\ub2e4. \uac01 \ubd80\ud488\uc758 \uc7a5\uc810 <a target=\"_blank\" href=\"https:\/\/cnkuangya.com\/ko\/%eb%b8%94%eb%a1%9c%ea%b7%b8\/how-dc-spd-prevents-costly-downtime-in-pv-systems\/\">DC \uc7a5\ube44\uc758 \uc548\uc804 \uc720\uc9c0<\/a> \uc11c\uc9c0\ub85c\ubd80\ud130 \ubcf4\ud638\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\uc791\ub3d9 \ubaa8\ub4dc<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">\ub300\uae30<\/h3>\n\n\n\n<p>\ub300\uae30 \ubaa8\ub4dc\uc5d0\uc11c\ub294 DC SPD\uac00 \ud56d\uc0c1 \uc900\ube44\ub418\uc5b4 \uc788\uc2b5\ub2c8\ub2e4. \uc774\uc0c1\ud55c \uc804\uc555 \ubcc0\ud654\uac00 \uc788\ub294\uc9c0 \uc2dc\uc2a4\ud15c\uc744 \uac10\uc2dc\ud569\ub2c8\ub2e4.

energy your DC SPD can take during a surge. There are two main ratings: nominal discharge current (In) and maximum discharge current (Imax). Type 2 SPDs, used near inverters in solar systems, work at voltages from 600V to 1500V. These SPDs have a nominal discharge current of 20kA and can take a maximum of 40kA. You need to pick a surge current rating that fits your area. Places with more risk need SPDs with higher ratings for better safety.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><p>\uc720\ud615 2 SPD\ub294 \uc778\ubc84\ud130 \uadfc\ucc98\uc758 \uc911\uc694\ud55c \ubd80\ud488\uc744 \ubcf4\ud638\ud569\ub2c8\ub2e4.<\/p><\/li>\n\n\n\n<li><p>600V~1500V\uc5d0\uc11c \uc791\ub3d9\ud569\ub2c8\ub2e4.<\/p><\/li>\n\n\n\n<li><p>Nominal discharge current (In) is 20kA.<\/p><\/li>\n\n\n\n<li><p>\ucd5c\ub300 \ubc29\uc804 \uc804\ub958(Imax)\ub294 \ucd5c\ub300 40kA\uc785\ub2c8\ub2e4.<\/p><\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<colgroup><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><\/colgroup><tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>SPD \uc720\ud615<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>\uacf5\uce6d \ubc29\uc804 \uc804\ub958(In)<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>\ucd5c\ub300 \ubc29\uc804 \uc804\ub958(Imax)<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>\uc720\ud615 2 SPD<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>20 kA<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>\ucd5c\ub300 40kA<\/p><\/td><\/tr><\/tbody>\n<\/table>\n<\/figure>\n\n\n\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<colgroup><col style=\"min-width: 25px;\"\/><col style=\"min-width: 25px;\"\/><\/colgroup><tbody><tr><th colspan=\"1\" rowspan=\"1\"><p>\uc11c\uc9c0 \uc804\ub958 \uc815\uaca9(kA)<\/p><\/th><th colspan=\"1\" rowspan=\"1\"><p>\uc124\uba85<\/p><\/th><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>20<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>\uc911\uac04 \uc815\ub3c4\uc758 \uc11c\uc9c0\uac00 \uc788\ub294 \uc7a5\uc18c\uc5d0 \uc801\ud569\ud558\uba70 \uacac\uace0\ud55c \ubcf4\ud638 \uae30\ub2a5\uc744 \uc81c\uacf5\ud569\ub2c8\ub2e4.<\/p><\/td><\/tr><tr><td colspan=\"1\" rowspan=\"1\"><p>40<\/p><\/td><td colspan=\"1\" rowspan=\"1\"><p>\uace0\uc704\ud5d8 \ubd80\uc704\uc5d0 \uac00\uc7a5 \uc801\ud569\ud558\uba70 \ub354 \uac15\ub825\ud558\uace0 \uc624\ub798 \uc9c0\uc18d\ub418\ub294 \ubcf4\ud638 \uae30\ub2a5\uc744 \uc81c\uacf5\ud569\ub2c8\ub2e4.<\/p><\/td><\/tr><\/tbody>\n<\/table>\n<\/figure>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u26a1 SPD\ub97c \uc124\uce58\ud558\uae30 \uc804\uc5d0 \ud56d\uc0c1 \uc11c\uc9c0 \uc804\ub958 \uc815\uaca9\uc744 \ud655\uc778\ud558\uc138\uc694. \uc774\ub807\uac8c \ud558\uba74 \uac15\ud55c \uc804\uc555 \uc11c\uc9c0\ub85c\ubd80\ud130 \uc2dc\uc2a4\ud15c\uc744 \uc548\uc804\ud558\uac8c \ubcf4\ud638\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">\uc751\ub2f5 \uc2dc\uac04<\/h3>\n\n\n\n<p>DC SPD\uac00 \uc11c\uc9c0\uc5d0 \uc5bc\ub9c8\ub098 \ube68\ub9ac \ubc18\uc751\ud558\ub294\uc9c0 \uc544\ub294 \uac83\uc774 \uc911\uc694\ud569\ub2c8\ub2e4. \uc751\ub2f5 \uc2dc\uac04\uc740 \uc7a5\uce58\uac00 \uc5bc\ub9c8\ub098 \ube68\ub9ac \uc2dc\uc2a4\ud15c\uc744 \ubcf4\ud638\ud558\uae30 \uc2dc\uc791\ud558\ub294\uc9c0\ub97c \ubcf4\uc5ec\uc90d\ub2c8\ub2e4. \ub300\ubd80\ubd84\uc758 DC SPD\ub294 1\ub098\ub178\ucd08 \uc774\ub0b4\uc5d0 \uc791\ub3d9\ud569\ub2c8\ub2e4. \uc774\uac83\uc740 \ub9e4\uc6b0 \ube60\ub985\ub2c8\ub2e4. \uc11c\uc9c0\ub294 \uc804\uc790 \uc81c\ud488\uc744 \uc989\uc2dc \uc190\uc0c1\uc2dc\ud0ac \uc218 \uc788\uae30 \ub54c\ubb38\uc5d0 \ube60\ub978 \uc751\ub2f5\uc774 \uc911\uc694\ud569\ub2c8\ub2e4.
