Input: 100V-240V AC, 50-60Hz; Output: DC 12V, rated power 12W. Wide Application: The 12V 12W 1A LED adapter is suitable for low voltage LED lights, such as Christmas tree lights, string lights, spotlights, lawn lamps, light curtains, holiday lighting, etc. Warm reminder: Please check the voltage, current, watts and (+/-) two connector holes for your device before purchasing. IP44 WATERPROOF: This IP44 rainproof low voltage adapter has continuous mode and can be used indoors and outdoors. 1. Reliability Temperature rise (burn-in): 85% to 95% load per unit, 40+/-5 degrees, 4 hours Leakage current: 0.25mAMax240Vac Dielectric withstand voltage (between primary and secondary), 3000Vac, 60S, 5mAMax MTBF: per MIL-HDBK-217F, full load, 25 degrees, over 50 000 hours 2. Protective function Short-circuit protection: the switching power supply can resume normal operation when the short-circuit is removed Over-current protection: once the fault of overcurrent removed, the switching power supply will automatically resume normal operation Overvoltage protection: When the output voltage of the switching power supply exceeds 150%-180% of the rated voltage, the power supply Switching power supply enters the protection state, and the switching power supply can resume normal operation after the fault is cleared. 3. Environment Operating temperature: 0-40 degrees under full load conditions Storage temperature: -20-85 degrees ty: 5% at 95% non-condensing Have a great time shopping!
