Choose the right power in order to increase the life of the power supply. Please choose a model with 30% more output power rating than the electrical appliance. For example, 80W electrical appliances, please use 100W power supply. 2. Consider the load characteristics. If the load is a motor, a light bulb or a capacitive load, and the current is large at the moment of power on, a suitable power supply should be selected to avoid overload. If the load is a motor, consider the voltage reverse during shutdown. 3. In addition, the working environment temperature of the power supply needs Package List 1 x Waterproof Power Supply
