5.1 Ožičenje
Carefully connect your power source and load to the module's terminals as shown in Figure 3.3. Ensure correct polarity:
- IN+: Positive input from your power source.
- IN-: Negative input from your power source.
- OUT+: Positive output to your load.
- IZLAZ-: Negative output to your load.
Tighten the screw terminals securely to prevent loose connections.
5.2 Početno napajanje
After wiring, apply power to the input terminals. The LCD display will light up, showing the current output voltage and current. The 'ON' indicator LED will illuminate if the output is active.
6. Uputstvo za upotrebu
6.1 Osnovni rad
- Uključivanje/isključivanje: Press the 'ON/OFF' button to enable or disable the output. The 'ON' LED indicates active output.
- Display Switching: Short press the 'SW' button to cycle through different display parameters: output voltage (V), output current (A), output power (W), accumulated capacity (Ah), accumulated time (h), and module temperature.
- Input/Output Display: Short press the 'U/I' button to switch between displaying the input voltage i izlazna voltage.
- Podešavanje Output Voltage/Current: Rotate the rotary encoder to adjust the output voltage or current. A short press of the rotary encoder will switch between voltage i trenutni načini podešavanja.
6.2 Postavljanje parametara zaštite
The module includes several protection features that can be configured:
- Uđite u način podešavanja: Long press the 'SW' button until the display shows a protection parameter (e.g., 'SET LUP').
- Parametri navigacije: Short press the 'SW' button to cycle through the protection parameters:
- LUP (Input Undervoltage zaštita): Default 5.8V.
- OVP (Output Overvoltage zaštita): Default 36V.
- OCP (Output Overcurrent Protection): Default 5A.
- OPP (Output Overpower Protection): Standardno 80W.
- OTP (Over-Temperature Protection): Podrazumevano 110°C.

7. Održavanje
- čišćenje: Use a soft, dry cloth to clean the module. Do not use liquids or abrasive cleaners.
- Rad ventilatora: The intelligent temperature-controlled fan will automatically activate when the module's temperature exceeds 50°C or the output current exceeds 1A. Ensure the fan vents are not obstructed to allow for proper airflow.
- Skladištenje: Modul čuvajte na suhom i hladnom mjestu, dalje od direktne sunčeve svjetlosti i ekstremnih temperatura.
8. Otkrivanje problema
- Nema prikaza/Nema napajanja: Check input power connections and ensure the input voltage is within the specified range (6.0-36V). Verify the power source is functioning correctly.
- Output Not Active: Ensure the 'ON/OFF' button has been pressed to enable the output. Check if any protection mechanisms (OVP, OCP, OPP, etc.) have been triggered.
- Netačan izlazni volumentage/Current: Verify settings using the rotary encoder. Ensure the load is within the module's capabilities.
- Pregrijavanje modula: Check for obstructions around the fan and heatsink. Reduce the load or ensure the ambient temperature is not excessively high. The fan should activate automatically under load.
- Protection Triggered: If a protection (e.g., OVP, OCP) is triggered, the output will shut off. Identify the cause (e.g., excessive load, incorrect voltage setting) and correct it before re-enabling the output.
9. Savjeti za korisnike
- Utilize the LCD display to continuously monitor all critical parameters (voltage, current, power, capacity, time, temperature) for optimal control and safety.
- Carefully adjust the protection limits (LUP, OVP, OCP, OPP, OTP, OAP, OHP) to match your specific application requirements and prevent damage to sensitive components.
- For applications requiring sustained high power, ensure the module is placed in an environment with good airflow to assist the intelligent cooling fan.
- The soft start feature helps protect connected loads during power-up, but be mindful of very high power loads that might still cause issues.
