ZK-5KX 0.6-36V 5A Voltage Reducer - Amplifier Module with Display

Technical Specifications

Usage

• Changing display parameters -- in the normal interface, press SW to change values below Vin and display contents between current A power W capacity Ah time h replace it. To switch the uplink display on the screen, long press the SW button and switch the display contents between input voltage IN and output voltage OUT.

• Setting the output voltage - press the U/I button in the normal interface to enter the voltage setting interface. It can be seen that a certain digit of the output voltage value flashes. Turn the potentiometer left and right to adjust the major and minor values. Short press the potentiometer to choose which output voltage to set. After setting, press the U/I button 2 times to return to the normal interface. Or it will automatically switch to normal interface after stopping working for 10s.

• Setting the constant current value (that is, the maximum current value allowed to be output by the module) -- press U/I in the normal interface to enter the constant current agar interface Press. Then press the U/I button and switch to fixed current value. You can see part of the constant current value flashing. Turn the potentiometer left and right to adjust the major and minor values. Short press the potentiometer to select which bit to set the constant current value. After setting, press U/I to exit the setting voltage constant current interface and return to normal, or automatically return to normal interface after stopping operation for 10s.
• Setting the default on/off state of module startup - long press U/I in the normal interface to enter the parameter setting interface. You can see that it shows "ON OFF" or "ON ON". “ON OFF” means the output is OFF by default when the power is ON, and “ON ON” means the output is ON by default when the power is ON. Long press the potentiometer to switch the two states. After setting, press U/I to return to the Unormal interface.

• Setting protection parameters on status and threshold -- long press U/I to enter the parameter setting interface in the normal interface. Press SW until the guard you want appears. LUP -- undervoltage protection threshold; OUP -- overvoltage protection threshold; OCP -- overcurrent protection threshold; OPP -- overpower protection threshold; OAP -- ultra capacity protection threshold; OHP timeout protection threshold; OTP -- extreme temperature protection threshold. Short press the potentiometer to select the bit you want to set the protection parameter. Long press the potentiometer to turn on or off the protection parameters (only timeout protection and super capacity protection can be set to turn on/off, and other protection parameters are on by default.). After setting, long press U/I to return to normal interface.

• 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. Calibration input voltage interface with CAL+IN+V symbol; Calibration output voltage interface with CAL+OUT+V symbol; Calibration output current interface with symbol CAL+OUT+A. Rotate the potentiometer left and right to adjust the size of the parameters. After the setting is completed, long press the potentiometer to confirm. Long press U/I to return to the normal interface.

Button Function Table

 

• There should be no short circuit between the IN input and the OUT output of the module.
• If the module wants to output at full load, the input voltage must be above 8V. When the input voltage is 5V, the output power is about 15W. The maximum module current rating is 4A, depending on the maximum output power such as 17V, the current should not be greater than 2A
• When this module is used above 3A and 35W, please strengthen heat dissipation!!!
• The module has the input undervoltage protection function (adjustable), which defaults to about 4.8v, and the output is automatically cut off after the value is lower than this value (note that the voltage at the module port is low) the low voltage protection threshold and the input current is relatively large do not ignore the partial voltage on the input cable).
