4.2 Assembly (if applicable)
If your converter came as a module requiring case assembly, follow these general steps. Refer to the video for visual guidance.
- Carefully remove any protective films from the acrylic case panels.
- Attach the standoffs to the main circuit board.
- Align the bottom acrylic panel with the standoffs and secure it with screws.
- Place the main circuit board onto the bottom panel, ensuring all ports and buttons align with the case openings.
- Attach the side panels and then the top panel, securing them with the remaining screws.

4.3 Wiring
Connect the input power source to the 'IN' terminals and your load to the 'OUT' terminals. Ensure correct polarity (+ to + and - to -) to prevent damage. The module includes reverse connection protection, but it is always best practice to double-check wiring.
5. Operating Instructions
This section details how to operate your DROK Buck-Boost Converter, including adjusting voltage and current, and understanding the display modes.
5.1 Button Functions
Image: Diagram illustrating the function of each button and knob on the converter.
- SW (Short Press): Toggle between input voltage and output voltage display.
- SW (Long Press): Enter/Exit the settings menu.
- V-SET (Short Press): Adjust voltage setting.
- I-SET (Short Press): Adjust current setting.
- OK/I (Short Press): Toggle display of output power (W), capacity (Ah), energy (Wh), time (h), and temperature (°C).
- OK/I (Long Press): Enter sleep mode and shut down.
- Rotary Encoder (Short Press): Toggle output ON/OFF.
- Rotary Encoder (Long Press): Enable/Disable lock function.
- Rotary Encoder (Rotate Left): Decrease numerical value.
- Rotary Encoder (Rotate Right): Increase numerical value.
5.2 Adjusting Voltage and Current
To adjust the output voltage or current, first ensure the output is OFF. Use the V-SET or I-SET buttons to select the parameter you wish to change, then use the rotary encoder to adjust the value. Short press the rotary encoder to turn the output ON/OFF.

5.3 Display Modes
Image: Explains various display modes on the LCD, including input/output voltage, current, power, capacity, energy, time, and temperature.
The LCD can display various parameters. Use the OK/I button to cycle through different display modes such as output power (W), accumulated capacity (Ah), accumulated energy (Wh), operating time (h), and internal temperature (°C).
5.4 Output Control
The output can be turned ON or OFF by a short press of the rotary encoder. When the output is ON, the "ON" indicator light will illuminate. When OFF, the light will be off.

6. Maintenance
- Cleaning: Keep the module clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
- Ventilation: Ensure adequate airflow around the module, especially if an external fan is installed. Do not block ventilation holes.
- Storage: Store the converter in a dry, cool environment when not in use.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/No power | Input power not connected or insufficient; faulty wiring. | Check input power supply and connections. Ensure input voltage is within 6-36V. |
| Output voltage/current cannot be adjusted | Output is ON; parameters are locked; rotary encoder issue. | Turn output OFF before adjusting. Long press rotary encoder to unlock. Check encoder functionality. |
| Buzzer sounds frequently | Protection mechanism triggered (e.g., overcurrent, overtemperature, undervoltage). | Check load for short circuits or excessive current draw. Ensure adequate cooling. Verify input voltage is stable and sufficient. Reduce output power if necessary. |
| LVP (Low Voltage Protection) triggered | Input voltage is below the set LVP threshold or too low for operation. | Increase the input voltage to a sufficient level for normal operation. |
