The ZK-5KX is a versatile DC-DC adjustable step-up/step-down power supply module. Whether you are building a DIY lab bench power supply, charging batteries, or driving LEDs, this module packs a lot of punch into a small form factor. 1. Key Specifications Input Voltage: 6.0V – 36V Output Voltage: 0.6V – 36V Output Current: 0 – 5.0A

Output Power: 80W (with natural heat dissipation; up to 100W with extra cooling) Voltage Resolution: 0.01V Current Resolution: 0.001A 2. Basic Controls & Interface

The interface consists of a digital encoder (the knob), two buttons (SW and U/I), and a clear LCD screen.

Rotary Encoder (The Knob): Used to adjust values. It also acts as a button when pressed.

ON/OFF Button: Short press to toggle the output on or off. Long press (2 seconds) to switch the display between the input voltage and output voltage.

SW Button: Short press to cycle through the bottom display options (Current (A), Power (W), Capacity (Ah), and Time (h)).

U/I Button: Short press to enter the Voltage and Current setting interface. 3. How to Set Voltage and Current

Setting your limits is the most important part of using the ZK-5KX.

Enter Setting Mode: Short press the U/I button. The voltage digits will start flashing.

Adjust Voltage: Turn the knob to change the value. Press the knob to move the cursor to the digit you want to change (for faster adjustments).

Adjust Current: Short press the U/I button again while in setting mode. The current digits will flash. Turn the knob to set your maximum current limit (essential for CC mode/charging).

Save and Exit: Short press the U/I button one more time or wait 10 seconds for it to auto-save and return to the main screen. 4. Advanced System Settings

To access the deeper "Software Protection" menu, long-press the U/I button for 2 seconds while the output is off. Turn the knob to scroll through these parameters:

LVP (Low Voltage Protection): Default 4.8V. The module turns off if the input voltage drops below this.

OVP (Over Voltage Protection): Default 37V. Protects your load from voltage spikes. OCP (Over Current Protection): Default 5.2A. OPP (Over Power Protection): Default 81W.

OAH (Over Capacity Protection): If enabled, the module shuts off after a certain Ah (Amp-hour) threshold is reached (great for battery charging).

OPH (Over Time Protection): Shuts off after a set amount of time.

To change a value, press the knob to select the digit and rotate to adjust. Long-press U/I again to save and exit. 5. Calibration (Use with Caution)

If your multimeter shows a different reading than the ZK-5KX screen, you can calibrate it: Long-press U/I to enter the settings. Scroll to find SET (calibration mode).

Match the screen value to your trusted multimeter by rotating the knob. 6. Safety Tips & Best Practices

Heat Management: While rated for 80W, the module can get very hot. If you are consistently pulling more than 3A or 50W, consider adding a small 12V fan to the heatsink.

Input vs. Output: Remember that buck-boost means it can output 12V even if your input is only 6V. However, your input power source must be able to handle the wattage (Volts x Amps) required by the output.

Common Anode Design: Avoid connecting the "Input -" and "Output -" wires together. This will bypass the current sensing resistor and could cause the module to fail or lose current limiting capabilities.

Are you planning on using this module for a specific project, like a solar charger or a lab power supply?

3.1 Mechanical Mounting

Procedure

  1. Mount the device on a DIN rail (EN 50022 standard). Ensure 50mm clearance above and below for ventilation.
  2. Connect power: As per the manual’s terminal diagram, connect V+ to +24V, V- to 0V. Double-check polarity—reverse polarity will blow an internal fuse (often marked F1).
  3. Wire an input test: Connect a pushbutton between IN1 and COM (NPN config means IN1 to +24V through the button).
  4. Wire an output test: Connect an LED with a 2.2kΩ resistor between OUT1 and 0V.
  5. Apply power. The LED should flash once (power-on self test PASS).
  6. Force the input using the manual’s “monitor mode” (typically by pressing MENU → I/O MON → ENTER).
  7. Check the output logic—the manual will show if the output is active-high or active-low.
