1>.ZK-DP2 can calibrate output voltage and output current.
2>.Calibrate output voltage:Long press right button when display output voltage into calibrate output voltage.Then the screen will flashing.Short press left button to decrease the value.Short press right button to increase the value.Long press right button again to save and exit setup mode.
3>.Calibrate output current:Long press right button when display output current into calibrate output current.Then the screen will flashing.Short press left button to decrease the value.Short press right button to increase the value.Long press right button again to save and exit setup mode.
1>.Over-Voltage Protection:Module will turn OFF output voltage automatically if output voltage is more then 30.5V.
2>.Over-Current Protection:Module will turn OFF output automatically if output current is more then 2A.
3>.Over-Power Protection:Module will turn OFF output automatically if output power is more then 15W.It will display ‘-OP-’.User need reduce load power and then press ‘ON/OFF’ button.
4>.Current error:Large display error when output current is less than 0.05A.It can not display output current if current is 10~40mA.
5>.Over Temperature Protection:Module will turn OFF output automatically if termperature is more then 100℃.It will display ‘-OT-’.User need reduce load power and then press ‘ON/OFF’ button.
1>.As a ordinary step down power module:
1.1>.Connect right input voltage at input terminal;
1.2>.Adjust CV constant voltage potentiometer to set output voltage according to require.Rotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted.
1.3>.Rotate CC potentiometer counterclockwise more than 10 turns at first.
1.4>.Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module)
1.5>.Rotate CC constant current potentiometer clockwise to set output current according to require over-current protection value.
1.6>.Test and using(E.g:Module’s maximum output current is 1A if display 1A on multimeter.Red LED indicator will turn on if output reach to 1A.Otherwise LED is OFF.)
1.7>.The output voltage will decrease due to the current sampling resistor at the output. The higher the current, the more the voltage is reduced.
1.8>.Output current can not keep fix value output.It changes with load.But It can not exceed set output current value.
2>.As a charger:
2.1>.Tops:Power supply 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>.Test output voltage by multimeter and adjust CV potentiometer to make sure output voltage reach to require floating charge voltage.(If charge a 3.7V lithium battery, adjust the output voltage to 4.2V)
2.5>.Rotate CC potentiometer counterclockwise more than 10 turns at first.
2.6>.Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module)
2.7>.Rotate CC constant current potentiometer clockwise to set output current according to require charge current value.
2.8>.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>.Test output voltage by multimeter at output terminal and adjust CV potentiometer to set output voltage to LED’s maximum working voltage.
3.4>.Rotate CC potentiometer counterclockwise more than 10 turns.
3.5>.Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module)
3.6>.Rotate CC constant current potentiometer clockwise to set output current according to require LED working current.
3.7>.Connect LED and test.
1>.It is a DC power module,So it can not connect to AC power.
2>.Please don’t short output.
3>.’IN-’ and ‘OUT-’ can not be connect together,otherwise module can not support constant current output.
4>.Please make sure input power is more than load power.
5>.Please step down output power if module is hot.
6>.Rotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted.
