Noise and wave consider this indicator LED power through professional equipment to quantify intuitive judgment Xi'an LED outdoor power plants, mainly through the filter and regulator 220V AC switching power supply into a variety of low-voltage direct current, direct current flag output noise LED smoothness directly related outdoor power, filter quality of the output DC level of the AC component in Xi'an LED outdoor power price, also known as the ripple factor Xi'an LED outdoor power supplier, the coefficient is as small as possible. At the same time the capacity and quality of the filter capacitor is also related to the current time there is a greater change in voltage stabilization process. LED power classification 1, according to the supply voltage divided: there are high voltage and low voltage AC85-265 1.5-36V2, press the power supply, there are sub .3 constant voltage source and a constant current source, the relationship between the input and output by isolation, isolation power supply and Africa. isolated power supply. [2] 4. The relationship between the input voltage and the output voltage, divided boost, buck, buck. and so on.
