Zk-5kx Manual ◎

If you notice minor variances between the ZK-5KX display readout and a high-precision bench multimeter, you can calibrate the voltage and current sensors manually. Turn off the output of the ZK-5KX.

Adjust the limit to a safe ceiling slightly above what your device under test expects to draw. Connect your device to the OUT+ and OUT- terminals. Short press the ON/OFF button to deliver power. Using the ZK-5KX for Battery Charging

Short press the button to cycle through the parameters: LVP, OVP, OCP, OPP, OAH, OWH, or OHP.

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).

Cycles through the bottom display line: Power (W), Capacity (Ah), and Run Time.

Short press toggles the output terminal power on or off. Long press switches the default boot state (whether the unit powers on with the output active or inactive). If you notice minor variances between the ZK-5KX

The manual’s table of DIP switch settings is a wall of numbers. Here is the cheat sheet for the three most common use cases:

| Specification | Details | | :--- | :--- | | | 6.0V - 36V DC | | Output Voltage | 0.6V - 36V DC (adjustable) | | Output Current | 0 - 5A Max (4A for long-term stable work) | | Output Power | 80W Max (natural heat dissipation ~35W, forced cooling ~50W) | | Display Resolution | Voltage: 0.01V; Current: 0.001A | | Conversion Efficiency | Approximately 88% | | Protections | Input reverse connection, output backflow prevention, undervoltage, overvoltage, overcurrent, overpower, overtemperature, timeout, and overcapacity | | Cooling | Intelligent temperature-controlled fan (activates >50°C or >1A) | | Dimensions | Approx. 79 × 43 × 48 mm |

Connect a fixed input source (like an old laptop power brick or a 24V industrial switching power supply) to the input terminals. Adjust the output voltage and maximum current limit to safely power prototype circuits on your workbench. Battery Charging Station Connect your device to the OUT+ and OUT- terminals

: For high accuracy, you can calibrate the readings. Long-press the button to enter setting modes and use the button to toggle through calibration points. Cooling Mechanics
