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 lights, light curtains, holiday lighting, etc. Warm Reminder: Please check the voltage, current, wattage, and (+/-) two connector connections of your device before purchasing. IP44 WATERPROOF: This IP44 rainproof low-voltage adapter has a continuous mode and can be used indoors and outdoors. 1. Reliability Temperature Rise (Soak Test): 85% to 95% load per unit, 40+/-5 degrees, 4 hours Leakage Current: 0.25mA Max @ 240Vac Dielectric Withstand Voltage (between primary and secondary): 3000Vac, 60S, 5mA Max MTBF: Per MIL-HDBK-217F, full load, 25 degrees, over 50,000 hours 2. Protection Function Short Circuit Protection: The power supply can resume normal operation once the short circuit is removed. Overcurrent Protection: When the overcurrent fault is removed, the power supply will automatically resume normal operation. Overvoltage Protection: If the output voltage exceeds 150%-180% of the rated voltage, the power supply enters protection mode and can resume normal operation after the fault is cleared. 3. Environment Operating Temperature: 0-40 degrees under full load Storage Temperature: -20-85 degrees Humidity: 5% to 95% non-condensing
