1>.As a ordinary step up/down power module:
1.1>.Connect right input voltage at input terminal;
1.2>.Short press UP and DOWN buttons to set output voltage according to require.LCD display CV symbol.
1.3>.Keep press SET button 1second to adjust output constant current value. Then press UP and DOWN buttons to set value. LCD display CC and SET symbol.
1.4>.Test and using(E.g:Module’s maximum output current is 2A if display 2A on multimeter.LCD will display symbol CC if output reach to 2A.Otherwise display CV.)
1.5>.The output voltage will decrease due to the current sampling resistor at the output. The higher the current, the more the voltage is reduced.
2>.As a charger:
2.1>.Tops:Power module can not be used as charger module if it does not support constant current function.The voltage difference between the battery with insufficient voltage and the charger is very large.Causes excessive charging current even damage the battery.So it need keep charging in constant current mode to reaching a certain level.Then automatically switch back to constant voltage charging.
2.2>.Make sure floating charge voltage and charge current for battery.If the lithium battery’s parameter is 3.7V/2200mAh, then the float charge voltage is 4.2V, and the maximum charging current is 1C, which is 2200mA.
2.3>.Connect right input voltage at input terminal.(Note:Please don’t connect load during set parameter).
2.4>.Short press UP and DOWN buttons to set output voltage according to require.LCD display CV symbol.
2.5>.Keep press SET button 1second to adjust output constant current value. Then press UP and DOWN buttons to set value. LCD display CC and SET symbol.
