Dust, rain splash, moisture condensation and occasional water immersion are common risks for field-deployed power supplies.<\/div>\n<\/div>\n<div>\n<div>Without adequate ingress protection, internal circuit boards suffer corrosion, short-circuit damage and unexpected shutdowns.<\/div>\n<\/div>\n<div>\n<div>For outdoor installations, industrial sites and surveillance deployments, ordinary open-frame power supplies cannot stand up to real-world conditions. Repair and replacement costs add up fast once water or dust damages power hardware.<\/div>\n<\/div>\n<div>\n<div>That is why many buyers prioritize high-IP rated models at the procurement stage. WEHO designs IP67 power supplies built to resist moisture and dust for demanding field deployments.<\/div>\n<\/div>\n<div>\n<div>When you evaluate project specifications, you should treat waterproof performance as a core selection indicator, not an optional extra feature. Even moderate humidity can gradually erode unprotected electronics over months of continuous operation.<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_an_IP67_Power_Supply\"><\/span>What Is an IP67 Power Supply?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>An IP67 power supply is an industrial power unit certified under the Ingress Protection rating system. The two-digit IP code defines its resistance against solid particles and liquid exposure respectively.<\/div>\n<\/div>\n<div>\n<div>The first digit measures dust resistance, while the second digit indicates liquid-proof capability.<\/div>\n<\/div>\n<div>\n<div>For IP67 grade, digit 6 represents complete dust-tight performance, preventing fine dust particles from entering the internal housing. Digit 7 means the unit can withstand temporary immersion in one-meter deep water for a limited time period.<\/div>\n<\/div>\n<div>\n<div>It is critical for you to understand that IP67 does not equal permanent underwater submersion. This rating targets accidental short-term immersion, not continuous underwater operation.<\/div>\n<\/div>\n<div>\n<div><a href=\"https:\/\/www.wehopower.com\/hi\/\" target=\"_blank\" rel=\"noopener\">\u0935\u0947\u0939\u094b<\/a> IP67 waterproof power supplies follow this standard.

IP67 certification validates performance under standardized laboratory test conditions.<\/div>\n<\/div>\n<div>\n<div>During official testing, the IP67 power supply is submerged into one-meter deep fresh water for 30 minutes. After this test, no harmful water intrusion is allowed inside the enclosure.<\/div>\n<\/div>\n<div>\n<div>This specification covers accidental drops into water, heavy rain exposure, splash and temporary flooding scenarios.<\/div>\n<\/div>\n<div>\n<div>You need to keep one key limitation in mind. This rating is based on intact enclosures, connectors and cable entries.

If your equipment only faces rain splash, IP65 may satisfy requirements.<\/div>\n<\/div>\n<div>\n<div>Once there exists risk of temporary water pooling or accidental submersion, you should pick IP67.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"IP66_vs_IP67_Power_Supply\"><\/span>IP66 vs IP67 Power Supply<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>IP66 supports strong high-pressure water washing, but cannot endure submersion. Factories requiring frequent surface cleaning often select IP66.<\/div>\n<\/div>\n<div>\n<div>If your site has both cleaning operations plus possible water immersion risk, IP67 becomes the safer choice.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"IP67_vs_IP68_Power_Supply\"><\/span>IP67 vs IP68 Power Supply<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>IP67 supports short-time immersion, while IP68 enables sustained underwater deployment. Most outdoor industrial projects do not demand IP68.<\/div>\n<\/div>\n<div>\n<div>IP67 can control your hardware cost effectively. WEHO provides both IP65 and IP67 waterproof power supply options for you to match different site conditions.<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"How_IP67_Power_Supplies_Achieve_Waterproof_Protection\"><\/span>How IP67 Power Supplies Achieve Waterproof Protection<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>Waterproof capacity is not achieved by a single modification. Multiple structural designs work together to deliver IP67-level ingress protection.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Sealed_Enclosure_Design\"><\/span>Sealed Enclosure Design<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>The metal or plastic enclosure forms the first defensive barrier. The housing shell needs precise dimensional tolerance.<\/div>\n<\/div>\n<div>\n<div>Joint gaps between upper and lower casing must be filled with compression-resistant sealing gaskets. Poor gasket material or loose assembly will directly break waterproof performance.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Potting_and_Encapsulation_Technology\"><\/span>Potting and Encapsulation Technology<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>Inside qualified IP67 power supplies, circuit boards are fully filled with insulating potting compound. This solid filling material wraps every electronic component.<\/div>\n<\/div>\n<div>\n<div>It stops moisture, dust and condensation from touching circuit traces. Good potting material also helps improve shock and vibration resistance for field-working power supplies.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Waterproof_Connectors_and_Cable_Entry_Design\"><\/span>Waterproof Connectors and Cable Entry Design<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>Cable in-and-out positions are frequent failure points for waterproof power supplies. Ordinary rubber cable glands cannot reach IP67 standards.<\/div>\n<\/div>\n<div>\n<div>Professional IP-rated waterproof connectors and cable glands prevent water from creeping in along cable surfaces. When you place orders, you should double-check whether supporting connectors match the power supply\u2019s IP grade.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Thermal_Management_in_Sealed_Enclosures\"><\/span>Thermal Management in Sealed Enclosures<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>Full sealing brings one obvious challenge: heat dissipation. Since there are no ventilation holes, all heat must dissipate through enclosure shell surfaces.<\/div>\n<\/div>\n<div>\n<div>WEHO IP67 power supplies adopt optimized thermal design for sealed housings. You must confirm the power supply can maintain full rated output under your site\u2019s highest ambient temperature.
