Press the to jump the cursor left or right to target the specific digit slot (hundreds, tens, units, or decimals).
The is a highly versatile, programmable digital power supply module capable of stepping voltage both up and down . Operating within an input voltage range of 6.0V to 36V and delivering an adjustable output of 0.6V to 36V at up to 5A (80W max) , it serves as an excellent budget bench power supply, solar charge controller, or battery charger.
One of the most powerful features of the ZK-5KX is its ability to be user-calibrated. Factory tolerances can sometimes lead to discrepancies of a few millivolts or milliamps. Because the module might "lie" about the input or output voltages slightly, calibration ensures accuracy. It is recommended to use a quality multimeter for calibration. Zk-5kx Manual
: Calibration must be done with care and requires some technical knowledge. Incorrect calibration can cause the module to malfunction or produce inaccurate readings.

Once the battery reaches its full target voltage, the module automatically switches to CV (Constant Voltage) mode. The current will begin dropping toward zero. Once the current drops near 0A, the battery is fully charged. 6. Troubleshooting and Common Error Codes
For parameters like and OPH , short press the ON/OFF button to toggle the function on or off (the display will show the target value when enabled, or ---- when disabled). One of the most powerful features of the
Set the maximum output current limit. OPP (Over Power Protection): Set the maximum wattage.
Short press the encoder knob to lock in the calibrated values. Turn off the input power to exit the calibration interface. 6. Common Applications Benchtop Lab Power Supply
button again to switch to current setting mode. Adjust the value to your desired limit (e.g., 1.0A for LED driving). Save & Exit: twice to save or wait 10 seconds for it to auto-save. Protection Mechanisms
