Power long overvoltage protection circuit when the supply voltage is below or above a certain value, Xi'an rain power sales, the protector off the line; when the supply voltage returns to the normal range, Xi'an rainproof power supply factory outlets, protection automatically turned on. 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, rain power has. isolated and non-isolated power supply. [2] 4. The relationship between the input voltage and the output voltage, divided boost, buck, buck. and so on.
