Short press the button to toggle between editing Voltage (V) and Current (A).

Yes (Prevents high current spikes during startup, though high-power loads may occasionally trigger protection if not managed). Operating Frequency: 180 kHz 2. Hardware Layout and Interface Breakdown

The combination of voltage and current exceeds the watt limit (e.g., 16V at 5.1A equals 81.6W, triggering an 81W OPP ceiling).

If you notice the voltage readout is slightly off compared to your multimeter, you can enter the calibration mode by holding "U/I" and "SET" simultaneously during power-up (refer to specific firmware versions for slight variations). Zk-5kx Manual

Features a rotary encoder knob. Pressing the knob allows you to switch between digits for rapid voltage or current adjustments. Function Buttons:

: A red LED indicating that the module has transitioned into Constant Current mode. Step-by-Step Operating Instructions 1. Switching the Display Screens

: Calibration must be done with care and requires some technical knowledge. Incorrect calibration can cause the module to malfunction or produce inaccurate readings. Short press the button to toggle between editing

Before you begin, it's important to understand the module's physical layout:

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.

When triggered, the protection will automatically turn off the output. The LCD screen will display a protection code. Hardware Layout and Interface Breakdown The combination of

The is a highly efficient, digitally controlled DC-DC power supply module capable of both stepping up (boosting) and stepping down (bucking) input voltage . Delivering up to 36V, 5A, and 80W of maximum power , it serves as an excellent foundational module for DIY bench power supplies, battery chargers, and LED driver systems.

One of the most popular uses for the ZK-5KX is as the core of a DIY variable benchtop power supply. By housing the module in a custom enclosure, you can create a professional-grade lab supply at a fraction of the cost.

Over time or after heavy use, the ZK-5KX may display values that are slightly off from the actual output. If you notice a discrepancy, you can recalibrate it.
