3: Outdoor & Harsh Climate Installations
* Why it fits: Europe’s diverse climate (scorching heat in the south, damp/snowy conditions in the north) and limited indoor space often require outdoor wall, garden, or eave mounting.
* Key strengths: IP66 ingress protection (dust-tight and protected against powerful water jets) – no extra enclosure needed; operating temperature from -25℃ to 60℃ (with smart derating above 45℃). The intelligent fan cooling ensures stable performance whether in the heat of Spain or the freezing winters of Germany.
* Key data support: IP66 rating; Operating temp -25℃~60℃; Smart cooling; Noise level only 50dB (does not disturb daily life even when installed indoors).
