Package include:

1 x Buck Boost Converter Power Supply Module 

Operating mode/setting temperature/return temperature setting:

1. In the operation interface, press the SET key briefly to enter the quick setting interface

2. After entering the quick setting interface, press the SET key briefly to switch the parameters to be set (working mode/setting temperature/return Differential temperature)

3. Modify the parameter value through the JP DOWN key, and support short press/long press

4. Press and hold SET for more than 3s or for 6s without any key operation, exit the quick setting interface, and save the parameters

Alarm temperature/delay start setting/temperature correction:

1. In the operation interface, press and hold SET for more than 3s to enter the parameter setting interface

2. After entering the parameter setting interface, press the SET key briefly to switch the parameters to be set (alarm temperature/delay start setting/temperature correction)

3. Use the UP DOWN key to modify the parameter value, and support short press/long press

4. Press and hold SET for more than 3s or for 6s without any key operation, exit the parameter setting interface, and save the parameters

How to turn on the high temperature alarm (default off):

1. Enter the parameter setting interface, switch to the alarm parameter ALA interface, and press the STOP key briefly to turn it on or off

2. High temperature alarm function; If the high temperature alarm function is turned off, ALA displays "--" as a reminder

How to enable delayed startup (default shutdown):

1. Enter the parameter setting interface, switch to the alarm parameter OPH interface, and turn on or off the high temperature by briefly pressing the STOP key

2. Alarm function; If the high temperature alarm function is turned off, OPH displays "-" as a reminder

Note: 

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

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

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.

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).
