                        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 interface operation instructions:
                        2.1. Press the encoder button for 3 seconds to enter the setting interface.
                        2.2. By adjusting the parameters of the rotary coded potentiometer, it can quickly rotate (fast raise / lower), and switch the parameters to be adjusted by pressing the key of the rotary coded potentiometer.
                        2.3. In the maximum capacity (OAH) / maximum energy (OPH) / maximum running time (OHP) interface, press the "ON / OFF" button to open or close the corresponding function, and if closed, display "-";
                        2.4. In the maximum capacity (OAH) / maximum energy (OPH) parameter interface, long press the ON / OFF button to change the range of capacity (9,999Ah / 99.99Ah / 9999999Ah, 9,999Wh / 99.999Wh / 99999999Wh);
                        2.5. After the parameter setting, hold the encoder potentiometer key for 3 seconds to 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 .
                        3. This product has locking function:

                        4. Product use method:
                        4.1. As a common boost-and-drop power supply with over-voltage / over-current / power / over-temperature / under-voltage protection;
                        (1) 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 be the "CC" state, Otherwise the liquid crystal will be the "CV" state. )
                        4.2. Use as a battery charger
                        Products without a constant current function cannot be used to recharge batteries. Due to the large voltage difference between batteries and chargers, the charging current is too large and the batteries are damaged. So the batteries must be charged with constant current at the beginning. When charging reaches a certain level, the batteries must be automatically returned to constant voltage charging.
                        (1) determine the floating charging voltage and current of the rechargeable battery u; (If the lithium battery parameter is 3.7 V / 2200 mAh, the floating charging voltage is 4.2 V, if it is 12 V rechargeable battery, the floating charging voltage is generally set to about 14 V).
                        (2) Under non-loaded state, the voltage value to the output voltage to reach the floating charging voltage; (if charging 3.7 V lithium battery, set the output voltage 4.2 V only)
                        (3) constant current value setting (battery charging current) under non-loaded state;
                        (4) connect the battery and charge.
                        4.3. Used as a LED Constant Current Driver
                        (1) Determine the working current and maximum voltage the LED you have to drive.
                        (2) Under non-loaded condition, the voltage and current values ​​to the output voltage reaches the maximum working voltage and current of the LED.
                        (3) close the LED and test it.
                        This product can reach the constant current value (between 0 and working current) LED polar dimming, no stroboscopic !!
                        5. Functional Details
                        5.1 Capacity / Energy / Running Time Statistics:
                        After OP, the statistics start automatically. After OFF, the value of the last state will be displayed. After OP is turned on again, the recording will start automatically. In the corresponding interface, the corresponding data is automatically deleted by pressing ON / OFF button for 3 seconds.
                        5.2 Maximum Capacity / Maximum Energy / Maximum Duration Setting
                        5.2.1. 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 switches the output, and "OAH" / flashes "OPH"; After the alarm is cleared, the capacity / energy statistics are automatically cleared;
                        5.2.2. 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 "OHP"; After the OHP alarm has been lifted, the automatic clearing time statistics;
                            This function can realize the quantitative / timing nutrition very well.
                        Note: When the functions of OAP / OPH and OHP are not enabled, the power supply will automatically record the capacity / energy and running time. When the functions of OAH / OPH and OHP are enabled, the power is automatically turned off and output after setting value. When the function of OHP is enabled, the running time of the power supply is countdown mode.
                        6. Notes:
                        6.1. Module input VIN-forbid short connection to output OUT-otherwise constant current function will fail.
                        6.2. Make sure the power supply is always greater than the power required by the output load!
                        6.3. If the module wants output at full load, the input voltage must be more than 8 V. When the input voltage is 5 V, the output power is about 15 W. The maximum current value of the module is 4A, provided the maximum output power is limited, such as 18 V , and the current must not exceed 2A.
                        6.4. Module has input under-voltage protection function, default is about 4.7 V, below this value, automatically disconnect the output, when the voltage is higher than 4.7 V, automatically restore the output (Note: 4.7 V is the voltage on the product port, when the current input is relatively large, do not ignore the partial voltage on the input wire).
