LED driven constant current charging 60V step-down power module with charging indicator CC CV LM2596HV

Instructions for use:
For safety reasons, please leave as much margin as possible. When connecting the input battery, consider the highest voltage when the battery is fully charged. The output voltage must not exceed 35V, and the output power (product of voltage and current) should not exceed 10W as much as possible; If it exceeds the limit, please add heat dissipation.
1. The fixed turn signal current is 0.1 times the constant current value (used to identify whether the battery is fully charged during charging);
2. Added input protection diode, which forms a circuit by connecting the input, consuming connection energy and protecting the module; If the energy is too high and the current surges, the s-shaped wiring on F1 on the PCB will be burned off, forming an open circuit, which further protects the module; At this point, only a thin copper wire needs to be connected to the F1 position to restore the output. If an overcurrent protector is added to the F1 position, it can be automatically restored. (Note: Some manufacturers claim to have added diodes to their modules without adding F1, so it is still impossible to protect the modules!)
