Protection mechanism:
1>.ZK-4KX supports reverse protection at input terminal.
2>.ZK-4KX supports anti-backflow protection at output terminal.
3>.LVP Under voltage protection. The default protection value is 4.8V and set range is DC 4.8V~30V adjustable. Screen will display OVP and flashing after start over voltage protection. In the battery discharge test, setting the appropriate LVP can effectively prevent the battery from being over-discharged, so as not to damage the battery.
3>.OVP over voltage protection. The default protection value is 31V and set range is DC 0.5V~31V adjustable. But user can modify the values as required. Screen will display OVP and flashing after start over voltage protection.

7>.OHP timeout protection. The default protection function is disabled. But user can modify the values as required and user can turn ON and set range is 00:00h~99:59h.Screen will display OAP and flashing after start over capacity protection.
8>.OTP over temperature protection. The default protection value is 110℃ and set range is 80℃~110℃ adjustable. Screen will display OTP and flashing after start over temperature protection.
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:
