DC-DC Step-down Constant Current Regulator Module for Charging

DC-DC Step-down Constant Current Regulator Module for Charging 5A 75W large power, in addition to the function of current limit, voltage stabilizing and step-down, the module can also be used as a high power LED constant current driver module and charging module for the lithium battery of usb connector. Two kinds of work mode: constant voltage and constant current. The red indicator light can show the current working status. Light up means constant voltage mode, light off means constant current mode. With current limit, short circuit, over temperature protection, the module can not be burned out even if the output is short circuit, which is more safe. Please don't reverse connection at the input port, otherwise the module will be burned out. Used as a charging module for lithium battery, blue light up means charging, blue light off and green light up means charging completed.Owning two high precision voltage and current pontentiometers, rotate the screw to adjust output voltage and current. How to set the current and voltage: 1. Adjust the constant-voltage potentiometer, make sure the output voltage to achieve what you need. 2. Directly connect the multimeter to the output ports at 10A current, to measure the output short circuit current, and adjust constant current pontentionmeter to make sure the output current to achieve the scheduled value. Length: 61mm Width: 26mm Height: 15mm Weight: 25g Input Voltage: 4V-38V(38V is max) Output Voltage: 1.25V-36V ( Used as a step down module, the input voltage muse be higher than output voltage more than 2V. ) Output Current: 5A (MAX), the output voltage can only be adjusted when the voltage is above 2V. Output Power: 75W (MAX, Please strengthen the cooling when the output is above 3A 35W.) Work Temperature: -45 to +85 degree centigrade Switching Frequency: 180KHz Transfer Efficiency: less than or equal to96% Short-circuit Protection: Yes (Limited current 8A) Over-temperature Protection: Yes (Automatically shut
