Power fan power supply fan is an important part, is responsible for the hot air out of the power within. Turn on the power inside you can see there are two large fin Xining wholesale power LED rain, and extreme performance parameters of high-power tube heat sink directly affects the safety load power supply and product costs. In addition, the rear two sockets are used to connect the external power supply and the LED display provides Xining rain socket power supply manufacturers, usually male socket for the power outlet. In between the two there is a voltage setting switch socket for switching 110V and 220V two voltage standard, widely used in the domestic standard 220V voltage, if the wrong file would be set on the 110V power supply damage. LED power life LED power life we ??think the impact of the performance, including environmental characteristics Xining LED waterproof power supply factory direct sales, parts and electricity levy to be integrated in the following areas: 1, affect the actual application environment: high humidity environment, high temperature, dusty environment, magnetic environment, vibration environment 2 and lighting temperature environment: temperature less than 65 degrees in the lighting, lighting shell is less than 75 degrees, the power supply temperature less than 60 degrees 3, the impact of the power supply network: Unstable grid voltage inputs have LED Power of parts impact, thus affecting the life of the LED driving pulse. 4, insulation and impact of the installation: the correct installation and good insulation products will increase power LED power supply applications.
