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, and holiday lighting. Warm Reminder: Please check the voltage, current, wattage, and connector size of your device before purchasing. IP44 Waterproof: This IP44-rated rainproof low-voltage adapter operates in continuous mode and can be used both indoors and outdoors. Reliability: - Temperature rise (burn-in): 85% to 95% load per unit, 405C, 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, 25C, over 50,000 hours Protective Functions: - Short-circuit protection: The switching power supply resumes normal operation after the short circuit is removed - Over-current protection: Automatically resumes normal operation once over-current condition is cleared - Overvoltage protection: When output voltage exceeds 150%-180% of rated voltage, the power supply enters protection mode and resumes after fault is cleared Environment: - Operating temperature: 0C to 40C under full load - Storage temperature: -20C to 85C - Humidity: 5% to 95% non-condensing
