The combination of IP67 protection rating, Class II insulation, and active PFC makes it suitable for both visible installations and integration into ceiling lights, false ceilings, or junction boxes in humid environments. The 5.5×2.1mm output connector with center-positive polarity is the de facto standard for CCTV cameras, IP intercoms, RGB LED strips, routers, hubs, and most consumer DC electronics.\u003c\/p\u003e\n\u003ch3\u003eKey Technical Advantages\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e🛡️ \u003cstrong\u003eIP67 rating\u003c\/strong\u003e — fully protected against dust and temporary immersion up to 1 meter for 30 minutes (IEC 60529 standard).

NEVER connect your system's yellow-green wire to the output load — this power supply is double-insulated, and the output only has +12V and GND, not a protective earth. The output GND is NOT equipotential to the system's earth: connecting them together can create ground loops that disturb CCTV video signals or introduce hum in audio installations. If you need to power multiple devices on the same data line, use only one common ground point on the load side, not on the mains side. And always check the connector polarity before connecting: 5.5×2.1mm center positive is the most common standard, but some devices (rare, but they exist) have reversed polarity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cimg alt=\"Oniroview Expert\" style=\"width: 100px; height: 100px; object-fit: cover; border-radius: 50%; border: 2px solid #b91c1c; flex-shrink: 0;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0260\/6222\/5485\/files\/Chi_siamo_oniroview.jpg?v=1751647335\"\u003e\n\u003c\/div\u003e\n\u003ch3\u003e\n\u003cbr\u003eComplete your project\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e🔗 DC 5.5×2.1mm male-female extension cable (to extend the distance from the load beyond the 50 cm of the integrated cable)\u003c\/li\u003e\n\u003cli\u003e🔗 5.5×2.1mm DC jack screw terminal (to terminate bare wires on loads without a standard connector)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use it outdoors thanks to its IP67 rating?\u003c\/strong\u003e\u003cbr\u003eThe Alpha Elettronica manual explicitly states \"not designed for outdoor use,\" so formally no — IP67 protects the power supply from accidental rain or heavy condensation, but it is not certified for continuous exposure to UV and outdoor thermal cycles.
