It features a 2-pole (2P) configuration and is designed to limit transient overvoltages on DC power lines caused by lightning and other voltage surges.<\/li>\n<li>The product has a nominal voltage (Un) of 1000V DC, a maximum continuous operating voltage (Uc) of 1060V DC, a nominal discharge current (In) of 20kA, a maximum discharge current (Imax) of 40kA, and a voltage protection level (Up) of \u2264 4.0kV. The device also has an IP20 degree of protection.<\/li>\n<li>The device features a plug-in\/removable module design, making inspection and replacement easier when necessary. Each module has a status indicator window. Green indicates that the module is operating normally. When the indicator turns red, the module should be checked and replaced according to the manufacturer's instructions.<\/li>\n<li>The KSPD-2P-DC40KA features dual thermal and overcurrent protection and can be configured with an optional remote signaling interface for status monitoring. The power terminals are clearly marked DC+ and DC-, making it easy to identify the correct polarity during installation.<\/li>\n<li>The device is designed for renewable energy systems such as solar and wind power systems, with voltage versions of 500V, 800V, and 1000V. The KSPD-2P-DC40KA 1000V version is particularly suitable for DC power lines with matching specifications, including solar power systems, DC distribution boards, DC power supply systems, and other renewable energy systems that require protection against voltage surges.<\/li>\n<li>In solar power applications, the device can be installed in DC distribution boards or at suitable locations along the DC power lines, depending on the system design, to help reduce the effects of transient overvoltages on downstream equipment. During installation, the correct DC+ and DC- polarity must be followed. Disconnect the power supply completely before installation, and ensure that all connecting wires are short, straight, securely connected, and have minimal bends.<\/li>\n<\/ul>\n<h3><span style=\"font-size: 18px;\">Specifications<\/span><\/h3>\n<ul>\n<li>Model: KSPD-2P-DC40KA<\/li>\n<li>Device Type: DC Surge Protective Device (SPD)<\/li>\n<li>Number of poles: 2P<\/li>\n<li>Power Supply: DC<\/li>\n<li>Nominal Voltage (Un): 1000V DC<\/li>\n<li>Maximum Continuous Operating Voltage (Uc): 1060V DC<\/li>\n<li>Nominal Discharge Current (In): 20kA<\/li>\n<li>Maximum Discharge Current (Imax): 40kA<\/li>\n<li>Voltage Protection Level (Up): \u2264 4.0kV<\/li>\n<li>Degree of Protection: IP20<\/li>\n<li>Module Type: Plug-in\/Removable Module<\/li>\n<li>Power Terminals\tDC+ \/ DC-<\/li>\n<li>Status Indicator\tGreen \u2013 Normal; Red \u2013 Replacement Required<\/li>\n<li>Protection Mechanism\tThermal and Overcurrent Protection<\/li>\n<li>Monitoring Capability\tOptional Remote Signaling Interface<\/li>\n<li>Connection Method\tConnected in Parallel with the DC Power Supply<\/li>\n<li>Installation Requirements\tShort, straight, securely connected wires with minimal bends<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Thi\u1ebft B\u1ecb Ch\u1ed1ng S\u00e9t Lan Truy\u1ec1n DC 2P 1000V 40kA KSPD-2P-DC40KA l\u00e0 thi\u1ebft b\u1ecb ch\u1ed1ng s\u00e9t lan truy\u1ec1n d\u00e0nh cho h\u1ec7 th\u1ed1ng \u0111i\u1ec7n m\u1ed9t chi\u1ec1u DC, c\u1ea5u h\u00ecnh 2 c\u1ef1c (2P), \u0111\u01b0\u1ee3c thi\u1ebft k\u1ebf \u0111\u1ec3 h\u1ea1n ch\u1ebf c\u00e1c xung qu\u00e1 \u0111i\u1ec7n \u00e1p xu\u1ea5t hi\u1ec7n tr\u00ean \u0111\u01b0\u1eddng ngu\u1ed3n do \u1ea3nh h\u01b0\u1edfng c\u1ee7a s\u00e9t v\u00e0 c\u00e1c hi\u1ec7n [&hellip;]<\/p>","protected":false},"featured_media":37266,"comment_status":"open","ping_status":"closed","template":"","meta":{"_yoast_wpseo_focuskw":"Thi\u1ebft b\u1ecb ch\u1ed1ng s\u00e9t","_yoast_wpseo_metadesc":"","_yoast_wpseo_focuskeywords":"","_yoast_wpseo_keyword_synonyms":""},"product_cat":[507],"product_tag":[],"class_list":["post-37263","product","type-product","status-publish","has-post-thumbnail","hentry","product_cat-cau-dao-dien-aptomat"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.9 (Yoast SEO v24.9) -
