Usage:

The module has two kinds of usage: one is simple mode,another is fully functional mode.The default is simple mode, if you need fully functional mode, you can open it by yourself.

 1, the correct connection input, output, ensure that the input voltage is within the required range , non -reverse, reverse will be bad , pay special attention to this point , fearing damage can be reversed itself 3A series diode current is greater than the input .
2, set the required voltage and current values , the method for setting the voltage and current values:
After power is the default display format voltage setpoint , the voltage value displayed is ” 00.00 ” , press “SET” button to switch to the current setting , the current value display format is ” 0.000 ” , press the button increasing the setting , press the button to reduce the set value , press accurately set , long press can quickly set .
3 After setting press “OK” button you can output the next output state when the voltage value is displayed by pressing the button you can increase the output voltage , the output voltage can be reduced by pressing the button , the current value in the display by The following keys can increase the current setting , press the button to reduce the output voltage and current settings , press accurately set , long press can quickly set up .
4 , the next output state short press “OK” button to switch the display output voltage, current , long press 3 seconds to auto rotate , long press again to cancel the round display .
5 , the next output state , press the “SET” button to turn off the output .
6 , more than five of the module is a simple model , which is the factory mode, you can see it is very simple and easy to use , if you want to save the recall stored values , or view the power , capacity and other parameters in the state of output you need to transform into full-function mode , full-function mode conversion method detailed instructions.

Fully functional mode usage:

This module has three special functions, the default is closed, if necessary, you can open them by yourself.

Function 0:After electricity,it will automatic output.

Function 1: Save and bring up the parameters, display the power and capacity.

Function 2: Automatic take turns to show parameters after output

Open/close method:

Long press the”OK” button, then electricity, the LED will take turns to show among “–0-“,”–1-“and”–2-” .When display “–0-“,release the”OK” button will open or close function 0, when display “–1-” ,release the”OK” button will open or close function 1, when display “–2-” ,release the”OK” button will open or close function 2. After releasing the “OK” button the digital tube display “–y-” said already open the current function, the digital tube display “–n-” said it already close the current function.

1.Enable the function 0, it will automatic output after electricity.

2.Enable the function 1, in the condition of no output, press “SET” button will take turns to display among voltage “00.00”, current “0.000”, bring up the parameters “Lo.- 0” and save the parameters “SA.- 0”. Below illustrate this function:

For example:we need store10V, 1.5 A in the storage location 1 and bring up the parameter from storage location 1.

1Press “SET” button to switch to the voltage value, setting voltage value of 10.00 V, press “SET” button to save the voltage value.

2Press “SET” button to switch to the current value, setting current value of 1.500 A, press “SET” button to save the current value.

3Press “SET” button to switch to the “SA.-0”, press theorbutton to select the storage location, here need to adjust to “SA.-1”, press “OK” button to store the “10 V, 1.5 A” in the storage location 1.

4Press “SET” button to switch to “Lo.-0”, press theorbutton to select the storage location which the parameter need to bring up, here need to adjust to “Lo.-1”,  then press the “OK” button to bring up the parameters of storage location 1.

5This module has total of 0 ~ 9 common 10 groups of storage location, the storage location can be set arbitrary voltage and current value.

3.Enable the function 2,after output,it will automatic take turns to display the parameters such as voltage, current, power and capacity.

Note:

1,Properly connect input and output, it is forbidden to reverse connection, or it will be burnout.

2,This module is a step-down module, input voltage need over output voltage more than 1.5 V.

3,Output under 2A natural cooling, output above 2A shall strengthen heat dissipation.

Display:

00.00: voltage value ,00.00 ~ 36.00 V

0.000: current value, 0.000 ~ 3.000 A

P. 000, P0.00, P00.0, P000. : power value, unit W, the position of the decimal point as the power to change the position. For example: P. 123 said 0.123 W, P1.23 said 1.23 W, P12.3 said 12.3 W, P102. said 102 W

C. 000, C0.00, C00.0 and C000. : capacity value, unit AH, the position of the decimal point as the volume change the position. For example: C.123 said 0.123AH, C1.23 said 1.23 AH, C12.3 said 12.3 AH, C123. said 123 AH

–0-,–1-,–2-:special function0, 1, 2,

–y-: open special functions

–n-: close the special function

SA. – * (*:0 ~ 9) : save the parameters to the store location 0 ~ 9
