Button/Potentiometer/LED introduction:
1. Long press means need keep press for more than 3second.
2. ON/OFF:Short Press to select enabled/disabled output.Long press is used to set default enabled/disabled output when power-ON.
3. IN/OUT:Short Press to switch display input voltage or output voltage or temperature.Long press is used to switch display output current or output power.
4. CV Potentiometer:Adjust output voltage.Increase the output voltage when rotating clockwise.
5. CC Potentiometer:Adjust output current.Increase the output current when rotating clockwise.
6. ON LED:Green LED.Output indicator.It will turn ON when there is a output at output terminal.
7. CC LED:Red LED.Constant current output indicator.It enters the constant current state when the load current reaches the set current and CC constant current indicator turns ON.
Using Steps:
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.
1.3 Rotate CC potentiometer counterclockwise more than 10 turns at first.
1.4 Short circuit between OUT+ and OUT-(Connect both by wire).Or 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 2A if display 2A on multimeter.Red LED indicator will turn on if output reach to 2A.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.
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 est output voltage by multimeter and adjust CC 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 Short circuit between OUT+ and OUT-(Connect both by wire).Or 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 Short circuit between OUT+ and OUT-(Connect both by wire).Or 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.
Note:
1. Input undervoltage protection voltage is 4.7V.Module need re-power if input less than 4.7V.
2. Please rotate the CV potentiometer counterclockwise more than 20 turns if there is no output voltage.
3. It is a DC power module,So it can not connect to AC power.
4. Module need re-power after short circuit protection.
5. Please connect input before connect battery when use as charge and make sure output voltage is higher than battery voltage.
6. ’IN-’ and ‘OUT-’ can not be connect together,otherwise module can not support constant current output.
7. Please make sure input power is more than load power.
8. Please step down output power if module is hot.
9. Please read use manual and description before use.
