Output voltage: DC 0.5V - 30.0V
Output current: 2A (max.)
Output Power: 15W (Max)
Voltage display accuracy: +/- 0.1V
Current display range: 0 - 2.2A
Current display accuracy: +/- 0.05A
Working current: 30mA
Efficiency (conversion efficiency): up to 95%
Features:
Supports fast charge protocols QC2.0, QC3.0, AFC, FCP, SCP.
Adjustment of output voltage and current.
4-digit display.
Two additional inputs: micro USB and Type C.
Overvoltage protection. The device will automatically cut off the voltage if the voltage exceeds 30.5V.
Overcurrent protection. The module will automatically cut off the output power if the current is more than 2A.
Overpower protection. The module will automatically cut off the output power if the power exceeds 15W. The display will show the error -OP-. It is necessary to reduce the load power and then press the ON/OFF button.
Over temperature protection. The module will automatically cut off the output power if the temperature exceeds 100°C. The display shows the error -OT-. It is necessary to reduce the load power and then press the ON/OFF button.
Attention! The device cannot display the output current if its value is below 50mA
Precautions:
ZK-DP2F is a DC power supply module, it cannot connect to AC power.
When using the device, please make sure the input power is higher than the load power.
Reduce the power output when the device heats up.
If the output voltage is not adjustable, turn the CV potentiometer counterclockwise more than 10 turns.
The output current cannot maintain a fixed value, it changes with the load.
There is a protective transport film on the surface of the device body.
Control
The device has three buttons - ON/OFF, SELECT and TRIG.
A quick press of the ON/OFF button turns on or off the output voltage, holding the button for more than 3 seconds sets the mode to on or off when the device is subsequently connected to power.
Each time you press the SELECT button, the display shows the readings of voltage, current and power, it is also possible to set an automatic alternating change of all readings on the display.
When connected to a power supply with QC2.0, QC3.0, AFC, FCP, SCP, the device will automatically detect the fast charge protocol, and the blue diode next to the TRIG button will light up. When the TRIG button is pressed for more than 3 sec. the device switches to manual selection of the required protocol. The numbers on the display start flashing. Each subsequent press of the TRIG button toggles between the possible protocols. AUTO - auto selection, OFF - complete disabling of protocol support. By pressing the ON/OFF button, select the desired value and hold down the TRIG button to exit the protocol selection mode.
Calibrating the output voltage and current
Press the SELECT button to switch the display to the voltage display mode. Hold the SELECT button for more than 3 seconds and release. The display starts flashing. By pressing the ON/OFF button we decrease the value, by pressing the SELECT button we increase it. By long pressing the SELECT button, we save the changes and exit the calibration mode.
To calibrate the current, switch the display to the current display mode and repeat the same manipulations.
