Internal sensor exceeded the safe thermal range. Ensure the integrated heatsink has adequate ventilation.
Short press the SW button to toggle the bottom line between Current (A), Power (W), Capacity (Ah), and Time (h). Setting Output Voltage: Short press the U/I button while on the main screen. Rotate the encoder knob to change the value.
The display will show an ON or OFF indicator icon in the lower portion of the screen. Adjusting Voltage and Current (Quick Method) Short press the button. The voltage digits will flash. Zk-5kx Manual
To set whether the device starts "ON" or "OFF" when powered: Long press to enter the parameter menu. Locate "OPEN OFF" (default off) or "OPEN ON" (default on).
The ZK-5kx series is a standalone fingerprint Time & Attendance system designed for small to medium-sized businesses. Developed by ZKTeco—a global leader in biometric security—this device is engineered to provide accurate employee tracking, eliminate "buddy punching" (one employee clocking in for another), and streamline payroll processing.
Set the maximum output current limit. OPP (Over Power Protection): Set the maximum wattage. | Specification | Details | | :--- | :--- | | | 6
The is a CNC DC-DC Buck-Boost Converter capable of handling up to 5A and 80W. It allows you to both increase (boost) and decrease (buck) input voltages between 6.0V and 36V to a stable output of 0.6V to 36V . Basic Operation Guide
With nothing connected to the output terminals, set the ZK-5KX output voltage to the exact floating charge target (e.g., 14.4V for a 12V Lead-Acid battery, or 4.2V for a single 18650 Li-ion cell).
I can provide custom calibration steps or tailor wiring diagrams to your project. Short press the SW button to toggle the
Many users find that these units benefit from a quick calibration to match their multimeter's readings. If your display seems slightly off, you can enter the calibration menu (usually by holding the encoder or specific button combinations) to fine-tune the accuracy.
Turns off the converter if the input voltage drops below a set threshold. OVP/OCP: Over-voltage and over-current protection. OPP: Over-power protection (typically capped at 82W).
Displays input/output voltage, current, power, capacity (Ah), energy (Wh), and running time.
The ZK-5KX is a versatile, digital DC-DC buck-boost voltage converter widely used by hobbyists, DIY electronics enthusiasts, and technicians. Combining a step-up (boost) and step-down (buck) regulator into a single compact module, it delivers a stabilized output voltage regardless of whether the input voltage is higher, lower, or equal to the target output.
