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. Reliability: Temperature rise (burn-in): 85% to 95% load per unit, 40+/-5 degrees, 4 hours. Leakage current: 0.25mA Max at 240Vac. Dielectric withstand voltage (between primary and secondary): 3000Vac, 60 seconds, 5mA Max. MTBF: per MIL-HDBK-217F, full load, 25 degrees, over 50,000 hours. Protective functions: Short-circuit protection: the switching power supply can resume normal operation when the short-circuit is removed. Over-current protection: once the overcurrent fault is removed, the switching power supply will automatically resume normal operation. Overvoltage protection: when the output voltage exceeds 150%-180% of the rated voltage, the switching power supply enters protection state and resumes normal operation after the fault is cleared. Environment: Operating temperature: 0-40 degrees under full load conditions. Storage temperature: -20-85 degrees. Humidity: 5% to 95% non-condensing.
