Input: 100V-240V AC, 50-60Hz; Output: DC 12V, 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 lights, light curtains, holiday lights, etc. Warm reminder: Check the voltage, current, wattage and (+/-) two connection holes for your device before purchasing it. 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. Protection function Short circuit protection: power can return to normal operation when the short circuit is removed Overcurrent protection: once the fault of overcurrent is removed, power will automatically return to normal operation. Overvoltage protection: When the output voltage from power exceeds 150%-180% of power, power goes off. power may return to normal operation after the error is corrected. 3. Environment Operating temperature: 0-40 degrees under full load Storage temperature: -20-85 degrees Humidity: 5% at 95% non-condensing
