A built-in long-life DC fan with temperature on/off control (≥50°C ON, ≤40°C OFF) holds full load from -20°C to +70°C; efficiency reaches up to 91–92% with <0.75W no-load consumption. Protections cover short circuit, overload (constant-current limit 3s then shutdown + re-power), over voltage and over temperature. It feeds multiple 5m rolls of 14.4W/m tape, ~15m of 18W/m RGBW, or 10–15m 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 (≈383W / 16A). Not waterproof—mount indoors or in a ventilated enclosure.
451W 24V Heavy Output: 24V DC, 18.8A, 451.2W; output trims 22.8–26.4V (±10%) to compensate cable drop on long 24V runs.
Switchable AC Input: 90–132VAC / 180–264VAC physical selector; 255–370VDC; withstands 300VAC surge for 5s.
1U Case + Smart Fan: 225×124×35mm, built-in DC fan with thermal on/off control, up to 91–92% efficiency, power-on LED, 5G vibration resistant, 3-year warranty.
Industrial Protection Logic: Short circuit / overload 105–150% (constant-current limit 3s → shutdown, re-power to recover) / over voltage 27.6–32.4V (shutdown + re-power) / over temp; IEC/UL 62368-1, EN60335-1, EN61558-1/-2-16, CCC/CE/CB/EAC.
Multi-Zone LED Ready: Several 5m 14.4W/m rolls, ~15m 18W/m RGBW, 10–15m 30W/m COB (with injection); controllers, CCTV, PLCs, signage, sensors on one supply.
