?Description of power supply parameters? Output voltage: 24V (DC Adjustable voltage range +5%/-10%) Current range (electric current): 0 to 20A Rated power: 480W Input voltage: AC110V/220V (85-145V /185-265V) Please switch the appropriate voltage before use Opening difference: +/-1%.< br> Efficiency: 80%.< br> Frequency is: 50-60Hz Temperature coefficient: ±0.03%/°C (0~50°C) Operating temperature: -10~60? Humidity during operation: 20-90%RH Storage temperature: -20?~85? Humidity during storage: 10%~ 95%RH Size: 215*115*50mm (L*B*H) Net weight: 0,8kg Connection L: AC input fire line.< br> N: AC input null conductor G: Grounding line -V:Negative (DC output) +V:Positive (DC output) Caution Note: The actual power is 80% of the rated power of the power supply (Example: If the power of your device is 800 watts, you need to buy a power supply with 1000 watts or more). When used indoors, the power supply is not waterproof. It is normal for the power supply to have a built-in fan and make a noise when it is working.
