After setting to CC, the constant current value is adjusted by default. When driving the LED, the fast dimming can be achieved by rotating the encoder, which is very convenient.

 

 

 

2. Setting up interface operation instructions:

2.1. Press the key of rotary encoder for 3 seconds to enter the setting interface.

2.2. By adjusting the parameters of the rotary encoded potentiometer, it can support fast rotation (fast increase/decrease), and switch the parameters to be adjusted by pressing the key of the rotary encoded potentiometer.

2.3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum running time (OHP) interface, press the "ON/OFF" button to select the opening or closing of the corresponding function, and if it is closed, display "--";

2.4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the ON/OFF button to select the range of capacity (9.999Ah/99.99Ah/9999999Ah, 9.999Wh/99.999Wh/99999999Wh);

2.5. After the parameter setting, press and hold the encoder potentiometer key for 3 seconds to exit the setting interface and save the setting parameters automatically;

 

Note: After product protection, output will be turned off, LCD will display the corresponding protection code (LVP/OVP/OCP/OPP/OAH/OPH/OHP) power chip itself also has various protection, if the chip itself is protected, OEP will be displayed.

 

3. This product has locking function:

Press the code potentiometer button for 5 seconds, lock the set voltage and current, prevent misoperation! After locking, press the code potentiometer button for 5 seconds to unlock!

 

4. Product use method:

4.1. As a common boost-and-drop power supply with over-voltage/over-current/over-power/over-temperature/under-voltage protection;

(1) Setting the voltage value.

(2) Set the constant current value (overcurrent protection value); (For example, the constant current value is 3.00A, then the maximum current of your product can only reach 3A, when the current reaches 3A, the liquid crystal will display the "CC" state, otherwise the liquid crystal will display the "CV" state.)

4.2. Use as battery charger

Products without constant current function can not be used to recharge batteries. Because of the great voltage difference between batteries and chargers, the charging current is too large and the batteries are damaged. So the batteries should be charged with constant current at the beginning. When the charging reaches a certain level, the batteries should be automatically switched back to constant voltage charging.

(1) Determine the floating charge voltage and current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, the floating charge voltage is 4.2V, if it is 12V rechargeable battery, the floating charge voltage is generally set to about 14V).

(2) Under no-load condition, set the voltage value to make the output voltage reach the floating charge voltage; (If charging 3.7V lithium battery, adjust the output voltage to 4.2V only)

(3) Setting constant current value (charging current of battery) under no-load condition;

(4) Connect the battery and charge it.

4.3. Used as LED Constant Current Driver

(1) Determine the working current and maximum operating voltage of the LED you need to drive.

(2) Under no-load condition, set the voltage and current values to make the output voltage reach the maximum working voltage and current of the LED.

(3) Connect the LED and test it.

This product can adjust the constant current value (between 0 and working current) to achieve LED polar dimming, no stroboscopic!!

5. Functional Details

5.1 Capacity/Energy/Running Time Statistics:

After ON, the statistics will start automatically. After OFF, the value of the last state will be displayed. After ON is turned on again, the recording will start automatically. In the corresponding interface, the corresponding data will be automatically cleared by pressing ON/OFF button for 3 seconds.

5.2 Setting Maximum Capacity/Maximum Energy/Maximum Running Time

5.2.1. Set the maximum capacity (OAH)/energy (OPH): When the OAH/OPH function is activated, when the statistical capacity/energy is higher than the maximum capacity/energy set, the power supply automatically shuts down the output, and flashes "OAH"/'OPH'; after the alarm is lifted, the capacity/energy statistics are automatically cleared;

5.2.2. Set the maximum discharge time (OHP): When the OHP function is activated, when the power supply runs longer than the set maximum discharge time, the power supply automatically closes the output and flickers to display "OHP"; after the OHP alarm is lifted, the automatic clearing time statistics;

    This function can realize the quantitative/timing power supply very well.

Note: When the functions of OAP/OPH and OHP are not turned on, the power supply will automatically record the capacity/energy and running time. When the functions of OAH/OPH and OHP are turned on, the power supply will automatically turn off and output after setting value. When the function of OHP is turned on, the running time of the power supply is countdown mode.

6. Notes:

6.1. Module input VIN-prohibit short connection with output OUT-otherwise constant current function will fail.

6.2. Make sure that the power of the power supply is always greater than the power required by the output load!

6.3. If the module wants to output at full load, the input voltage should be more than 8V. When the input voltage is 5V, the output power is about 15W. The maximum current value of the module is 4A, provided that the maximum output power is limited, such as 18V, and the current should be no more than 2A.

6.4. Module has input undervoltage protection function, default is about 4.7V, below this value, will automatically disconnect the output, when the voltage is higher than 4.7V, will automatically restore the output (Note: 4.7V is the voltage at the product port, when the input current is relatively large, do not ignore the partial voltage on the input wire).
