Input: 100Vto240V AC, 50to60Hz 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 (burntoin): 85 percent to 95 percent load per unit, 405 degrees, 4 hours Leakage current: 0.25mAMax240Vac Dielectric withstand voltage (between primary and secondary), 3000Vac, 60S, 5mAMax MTBF : per MILto HDBKto217F, 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 percent to180 percent of power, power goes off. power may return to normal operation after the error is corrected. 3. Environment Operating temperature: 0to40 degrees under full load Storage temperature: to20to85 degrees Humidity: 5 percent at 95 percent nontocondensing
