3.NOTE before using:

1. Output must be used isolated, not in series or on parallel, otherwise it will be burnt.
2. before using, please connect all wire well first, then turn on the input power supply, not turn on the input power supply first,
then connect the wire. Otherwise it will cause the fuse and MOS damaged.
3. when you get the product in the first time, please don't use your hands to touch the components, because human static
electricity can damage some chips.
4.You must make sure that the input voltage is 1.1 times higher than output voltage. Under large current circumstances, pay
attention to heat elimination. 
5.When the current is more than 10A or the temperature is more than 45 °c , the fan will begin to work. when the temperature is more than 65°c, the module will stop working.
6. if you use AC-DC converter or transformer coil, please add rectifier (rectifier bridge) and filter (more than 4700uf filter
capacitor). If input power supply is unstable, please add LC, L is over 47uf, C is over 2200 uf.
