Using Steps: 1>.As a ordinary step up/down power module: 1.1>.Connect right input voltage at input terminal; 1.2>.Rotary potentiometer to set output voltage according to require. LCD display CV symbol. 1.3>.Keep press potentiometer 1second to adjust output constant current value. Then rotary potentiometer to set value. LCD display CC and SET symbol. 1.4>.Test and using(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>.Rotary potentiometer to set output voltage according to require. LCD display CV symbol. 2.5>.Keep press potentiometer 1second to adjust output constant current value. Then rotary potentiometer to set value. LCD display CC and SET symbol. 2.6>.Connect battery at output terminal and start to charging. 3>.As a high power LED constant current driver: 3.1>.Make sure LED working current and maximum working voltage. 3.2>.Connect right input voltage at input terminal.(Note: Please don’t connect load during set parameter). 3.3>.Rotary potentiometer to set output voltage according to require. LCD display CV symbol. 3.4>.Keep press potentiometer 1second to adjust output constant current value. Then rotary potentiometer to set value. LCD display CC and SET symbol. 3.4>.Connect LED and test. Note: 1>.It needs to add extra cooling equipment if output current is more than 3A or output power is more than 35W. 2>.It is a DC power module, So it can not connect to AC power. 3>.Please connect input before connect battery when use as charge and make sure output voltage is higher than battery voltage. 4>.’VIN-’ and ‘OUT-’ can not be connect together. Otherwise module can not support constant current output. 5>.Keep input more than 8V is need if need ZK-4KX output in maximum power. It just can output about 15W when input 5V. 6>.Please make sure input power is more than load power. 7>.Please step down output power if module is hot. 8>.Please read use manual and description before use. Application: 1>.Ordinary power supply; 2>.Battery charger; 3>.LED drive power; 4>.Instrument voltage display; 5>.Test meter; 6>.Circuit test; 7>.Power conversion.
