4. Мере предострожности
- Always ensure correct polarity when connecting input and output. Incorrect connections can damage the module and connected devices.
- Немојте прекорачити максималну улазну запреминуtage (30V) or output current/power ratings.
- Ensure adequate ventilation, especially when operating at higher currents or power levels, to prevent overheating. Consider auxiliary cooling for loads above 3A/30W.
- Avoid touching the module components during operation, as some parts may become hot.
- Keep the module away from moisture, dust, and static electricity.
- This module is intended for use by individuals familiar with basic electronics and electrical safety.

5.1. Везе
- Улазна веза: Connect your DC power source to the 'IN+' (positive) and 'IN-' (negative) terminals. Ensure the input voltagе је у опсегу од 5.5V до 30V.
- Излазна веза: Connect your load or device to the 'OUT+' (positive) and 'OUT-' (negative) terminals.
5.2. Initial Voltagе Подешавање
Before connecting a sensitive load, it is recommended to adjust the output voltagе до жељеног нивоа.
- Connect the input power source.
- Користите мултиметар да измерите запреминуtage across the 'OUT+' and 'OUT-' terminals.
- Locate the small potentiometer (trimmer) on the module.
- Using a small screwdriver, gently turn the potentiometer clockwise to increase the output voltage or counter-clockwise to decrease it, until the desired voltagе се достиже.
Слика 3: Запреминаtage adjustment potentiometer is located near the output terminals. Turning it clockwise increases the output voltage.
6. Упутство за употребу
Once the module is set up and the output voltage is adjusted, it will maintain the set output voltage even if the input voltage fluctuates within its specified range (5.5V to 30V).
6.1. Load Considerations
The module can handle up to 3A/30W with natural heat dissipation. For applications requiring higher current or power (up to 4A/50W), auxiliary cooling such as a heatsink or fan is necessary to prevent overheating and ensure stable operation.

7. Одржавање
- Држите модул чистим и без прашине и прљавштине.
- Редовно проверавајте везе како бисте били сигурни да су безбедне.
- Monitor the module's temperature during operation, especially under heavy loads. If it becomes excessively hot, reduce the load or improve cooling.
- Avoid physical shock or excessive vibration to the module.
КСНУМКС. Решавање проблема
8.1. No Output Voltage
- Проверите улазно напајање: Уверите се да је јачина звука на улазуtage is within the 5.5V-30V range and the power source is functioning correctly.
- Verify connections: Confirm that 'IN+' and 'IN-' are correctly connected to the power source and 'OUT+' and 'OUT-' to the load.
- Check for short circuits: Disconnect the load and measure the output voltagе. Ако је волtage appears, there might be a short circuit in your load.
8.2. Оутпут Волtage is Unstable or Incorrect
- Adjust potentiometer: Re-adjust the output voltage using the onboard potentiometer.
- Check load: Ensure the load current/power does not exceed the module's maximum ratings. Overloading can cause voltage drop or instability.
- Инпут волtage fluctuations: Verify the input voltage is stable. Significant fluctuations in input can affect output stability if the module is operating at its limits.
- Overheating: If the module is hot, it may be throttling output. Improve cooling.
8.3. Module Overheats
- Reduce load: Decrease the current drawn from the module.
- Improve ventilation: Ensure the module is in an open area with good airflow.
- Add auxiliary cooling: For loads exceeding 3A/30W, attach a heatsink to the main power components or use a cooling fan.
