4Button/Potentiometer/LED introduction:
1>Long press means need keep press for more than 3second
2>Button ON:Short press to turn ON or OFF output voltageLong press is used to turn ON or OFF screen meanwhile voltage keep output
3>Button SW:Short press to switch display output voltage,output current or display these parameters in turnLong press is used to enter or exit calibration mode
4>CV Potentiometer:Adjust output voltageIncrease the output voltage when rotating clockwisePlease rotate the CV potentiometer 10 turns in counterclockwise if the output voltage cannot be adjusted
6>V LED:Red indicatorIt will turn ON when display output voltage
7>A LED:Blue indicatorIt will turn ON when display output current
8>Input terminal:There are three input methods:
81>Method 1:Standard Type A USB Male It just can input DC 5V
82>Method 2:Micro USB FemaleIt just can input DC 5V
83>Method 3:IN and IN- padsIt can input DC 35V-120V
84>It can only choose one input method
9>Output terminal:KF-301-2P 508mm blue terminal It can output DC 12V-240V
5Accuracy Calibration:
1>ZK-DPL can calibrate output voltage and output current accuracy
2>Calibrate output voltage accuracy:Long press button SW when display output voltage into calibrate output voltageThen the screen will flashingShort press button ON to decrease valueShort press button SW to increase valueLong press button SW again to save and exit setup modePress multiple times to change value
3>Calibrate output current accuracy:Long press button SW when display output current into calibrate output currentThen the screen will flashingShort press button ON to decrease valueShort press button SW to increase valueLong press button SW again to save and exit setup modePress multiple times to change valueThe higher the current, the more accurate the calibration valueIt can not display if output current is less than 10~30mA
6Using Steps:
1>Connect right input voltage at input terminal;
2>Adjust CV constant voltage potentiometer to set output voltage according to requireRotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted
3>Remove input power supply and then connect load at output
4>Re-connect input power supply to use module
5>Output current can not keep a fix value outputIt changes with loadBut output power can not exceed 3W
7Note:
1>It is a DC power module,So it can not connect to AC power
2>Please don't short output
3>'IN-' and ‘OUT-' can not be connect together,otherwise module can not support constant current output
4>Please make sure input power is more than load power
5>Please step down output power if module is hot
6>Rotate CV potentiometer counterclockwise more than 10 turns if the output voltage can not be adjusted
7>Output current can not keep a fix value outputIt changes with loadBut output power can not exceed 3W
8>Please read use manual and description before use
8Application:
1>Ordinary power supply;
2>Instrument voltage display;
3>Test meter;
4>Circuit test;
5>Power conversion
9Package:
1>1pc ZK-DPL DC-DC 3W Buck Boost Voltage Converter
