LED power classification 1, according to the supply voltage divided: there are high voltage and low voltage AC85-265 1.5-36V2, according to Xi'an power supply LED rainproof power supply, there are sub .3 constant voltage source and a constant current source, the press relations input and output isolation LED. rain power, isolation and non-isolated power supply. [2] 4. The relationship between the input voltage and the output voltage, divided boost, buck, buck. and so on. LED power supply LED power supply is a power supply LED rainproof power Xi'an professional production, is providing power to electronic equipment device, also known as the power supply LED waterproof power suppliers Xi'an, deploy different power inputs on the device attached to the belt There are two or three separate power input circuit apparatus. (Light emitting diode) and other known battery power; through the transformer and rectifier, the alternating current into direct current power supply device called a rectifier. To provide an electronic device called a signal source. Transistor can be amplified signal sent, again amplified signal is transmitted to the back of the circuit to go. Transistor on the back of the circuit can also be seen as a signal source. Rectifier power supply, sometimes the source. Xi'an LED waterproof power supply Direct _ Chun away Lighting (certified) _LED rain is powered by Shenzhen far Lighting Limited. Lighting Co., Ltd.
