1.25-53V Adjustable Voltage Reducer Buck DC-DC 20A 300W Power Supply Car LED ZEN
This is a DC-DC step down converter module that convert 12V~55V to 1.25V~53V.
The module supports USB interface, the rated current is 2A and rated voltage 5V, that could be used as charger or power supply for USB equipment.
It has a DC 12V high quality cooling fan which will automatically start up or stop due to module working state.
Current is related to voltage difference and temperature. When it is large current and causes to much heat for chip, it will automatically reduce output power. Due to the limit of maximum power, maximum current will differ according to various output voltage.
The input voltage limit is 55V, and when input voltage is more than 55V, master control chip will burn out as well as module will be damaged.
