Operation
|
|
|
|
|
|
|
|
|
|
|
|
|
|
1. Switch display parameters -- in the normal interface, press SW to switch the display
|
|
|
|
|
|
|
below the display screen, and switch the display content between current A power W |
|
|
|
|
|
|
capacity Ah time h.Long press SW button to switch the uplink display on the display |
|
|
|
|
|
|
screen and switch the display content between input voltage IN output voltage OUT. |
|
|
|
|
|
|
2. Set output voltage -- press U/I button in the normal interface to enter the interface
|
|
|
|
|
|
|
of setting voltage constant current.It can be seen that a certain digit of the output |
|
|
|
|
|
|
voltage value is flashing. Rotate the encoder left and right to adjust the major and |
|
|
|
|
|
|
minor.Short press the rotary encoder to choose which bit of output voltage to set.After |
|
|
|
|
|
|
setting, press U/I button 2 times to return to the normal interface.Or automatically |
|
|
|
|
|
|
return to the normal interface after stopping operation for 10s. |
|
|
|
|
|
|
3. Set constant current value (that is, the maximum current value allowed to output by
|
|
|
|
|
|
|
the module) -- press U/I button in the normal interface to enter the setting voltage |
|
|
|
|
|
|
constant current interface.Then press U/I button and switch to setting constant |
|
|
|
|
|
|
current value. You can see a bit of the setting constant current value flashing. Rotate |
|
|
|
|
|
|
the rotary encoder left and right to adjust the major and minor.Short press the rotary |
|
|
|
|
|
|
encoder to choose which bit to set the constant current value.After setting, press U/I |
|
|
|
|
|
|
to exit the setting voltage constant current interface and return to the normal |
|
|
|
|
|
|
interface.Or automatically return to the normal interface after stopping operation for 10s. |
|
|
|
|
|
|
4. Set the default on/off state of module power-on -- long press U/I in the normal
|
|
|
|
|
|
|
interface to enter the parameter setting interface.You can see that it shows "OPEN |
|
|
|
|
|
|
OFF" or "OPEN ON". "OPEN OFF" means the output is turned OFF by default when |
|
|
|
|
|
|
power is ON, and "OPEN ON" means the output is turned ON by default when power is |
|
|
|
|
|
|
ON.Long press rotate encoder to switch two states.After setting, long press U/I to |
|
|
|
|
|
|
return to the normal interface. |
|
|
|
|
|
|
5. Setting of protection parameters on state and threshold -- long press U/I to enter
|
|
|
|
|
|
|
the parameter setting interface in the normal interface.Press SW until the protection |
|
|
|
|
|
|
you want appears.LUP -- undervoltage protection threshold;OUP -- overvoltage |
|
|
|
|
|
|
protection threshold;OCP -- overcurrent protection threshold;OPP -- over power |
|
|
|
|
|
|
protection threshold;OAP -- ultra-capacity protection threshold;OHP timeout |
|
|
|
|
|
|
protection threshold;OTP -- overtemperature protection threshold.Short press rotate |
|
|
|
|
|
|
encoder to select which bit you want to set the protection parameter.Long press the |
|
|
|
|
|
|
rotary encoder to set the protection parameters on or off (only timeout protection |
|
|
|
|
|
|
and supercapacity protection can be set to turn on/off, and other protection |
|
|
|
|
|
|
parameters are turned on by default.).Rotate the encoder left and right to make the |
|
|
|
|
|
|
parameters bigger and smaller.After setting, long press U/I to return to the normal interface. |
|
|
|
|
|
|
6. Calibration voltage and current -- press U/I button to enter the parameter setting
|
|
|
|
|
|
|
interface under normal interface.Press SW until a parameter interface with CAL |
|
|
|
|
|
|
appears.The calibration input voltage interface with the symbol CAL+IN+V;The |
|
|
|
|
|
|
calibration output voltage interface with the symbol CAL+OUT+V;The calibration |
|
|
|
|
|
|
output current interface with the symbol CAL+OUT+A.Rotate the encoder left and |
|
|
|
|
|
|
right to adjust the size of parameters.After the adjustment is completed, long press |
|
|
|
|
|
|
the rotary encoder to confirm the adjustment is completed, and the parameter value |
|
|
|
|
|
|
is no longer flashing.Long press U/I to return to the normal interface.
Note: in order to |
|
|
|
|
|
|
ensure the accuracy of calibration, calibration voltage -- above 12V can only be |
|
|
|
|
|
|
started;Calibration current - start calibration only when the current is above 1A. |
