Features:
1.The product adopts the original chip, high quality capacitors, input TVS protection, quality is guaranteed!
2. The product in the design, materials, PCB process under the effort, so that the module can be done in a very small volume above the very considerable parameters and functions
3. Module size is relatively small, the heat dissipation area is limited, high-power output heating is a normal phenomenon
4. The product has output short-circuit protection, built-in over-temperature protection, safer and more secure to use
Parameter:
IN+: DC input positive 6V-40V (need to be higher than the output 1V or more)
IN-: DC input negative, connected with the output negative pole
OUT+: DC output positive
OUT-: DC output negative terminal, connected to the negative terminal of the input.
Attention:
1. The product input should be greater than the output voltage, to maintain a pressure difference of more than 1V is best, the input can not be reversed, reverse burn board!
2. wiring is best to disconnect the power supply, otherwise when the voltage is high, it is easy to spark, so there is a certain risk of striking the chip, breakdown chip
3. Wiring can not be too thin, to ensure that the wire can withstand the corresponding current
4. Good protection of inductive loads, to avoid excessive reverse electromotive force beyond the chip's tolerance range
5. The higher the power of the module, the closer the current is to the maximum current. The more heat will be generated, pay attention to the use of heat dissipation
6. In the absence of external heat dissipation, the continuous use of current is recommended below 3A, more than 3A requires additional heat dissipation, otherwise it will overheat to protect the output.
7. The use of voltage is recommended below 38V, because if the supply voltage is not very stable, the spike voltage exceeds 40V will trigger the chip internal over-voltage protection, for stable operation, appropriate to leave some margin!

How to choose the correct size:
Step 1 Please measure your foot length carefully.
Step 2 Please choose the correct size according to your foot length and chinese size.
For example, If your foot length is 255 mm , you should choose the size 8.
