5.With output short circuit protection function

Product description:
Non-isolated step-down module
High voltage input, ensure that the voltage peak cannot be higher than the calibration value.
For high voltage input, please connect it safely to avoid damage, and do not pat it if you do not understand the relevant electrical technology.
The 5V output can be used to charge the mobile phone, and the 12V output cannot be used to charge the mobile phone.
When wiring, the USB interface should not be loaded. After connecting, make sure that the output voltage of the USB interface meets the voltage you need before use.
If the voltage is high and the voltage is reduced, the heat will be greater. Do not pat if you mind.

Parameters:
Input: 9-85V wide voltage input (recommended for use within 80V)
Output: 5V/12V optional, maximum 2A output
AC 56V input (peak value cannot exceed 86V)
Input with thermal sensing protection
Low standby power consumption
With overcurrent protection function
With overheat protection function
With output short circuit protection function
Can be used with the shell (the shell needs to be assembled)

Application:
Electric vehicle, unicycle, mobile phone charging on-board power supply, battery for mobile phone, recorder and other equipment

Package include:
Package 1:
1X module
Package 2:
1X module
1X housing

common problem:
*Does it support fast charging?
This is normal charging.
*Is the module safe?
The module is normal as long as the input voltage does not exceed the use voltage. However, it is difficult to ensure that the power supply voltage is stable and pure in general. Sparks in the wiring, interference from other equipment, etc., may cause the power supply voltage to be much higher in an instant. Therefore, if the mobile phone is charged, it is recommended to input less than 76V, which is safer.
*Does it support mobile phones and DASH CAM?
Yes, the voltage of other equipment can be matched, and the current can not exceed 2A
