A built-in long-life DC fan with temperature on/off control (≥50°C on, ≤40°C off) supports full load from -25°C to +70°C; efficiency is up to 88–89% with <0.75W no-load consumption. Protections cover short circuit, overload (hiccup auto-recovery), over voltage and over temperature. It powers multiple 5m rolls of 14.4W/m 24V tape, ~10m of 18W/m RGBW, or 8–10m of 30W/m COB with injection. Ideal for commercial LED installs, DMX/PWM controllers, CCTV, PLCs and industrial automation. For 24/7 use de-rate to 85% load (≈298W / 12.4A). Not waterproof—mount indoors or in a ventilated enclosure.
350W 24V Heavy-Duty: 24V DC, 14.6A, 350.4W; output trims 21.6–28.8V to compensate cable drop on long 24V runs.
Switchable AC Input: 90–132VAC / 180–264VAC physical selector; 240–370VDC; withstands 300VAC surge for 5s.
1U Case + Smart Fan: 215×115×30mm, built-in DC fan with thermal on/off control, up to 89% efficiency, power-on LED, 5G vibration resistant, 3-year warranty.
Full Protection Suite: Short circuit (auto recovery), overload 110–140% (hiccup), over voltage 28.8–33.6V (hiccup), over temp (hiccup/recovery); UL/IEC/EN 62368-1, EN60335-1, EN61558-1/-2-16, CCC/CE/CB.
Multi-Roll LED Ready: Several 5m 14.4W/m rolls, ~10m 18W/m RGBW, 8–10m 30W/m COB (with injection); controllers, CCTV, PLCs, signage, sensors on one supply.
