- Volume de sortie réglabletage: A multi-turn potentiometer allows precise voltage réglage.
- Protection intégrée : Thermal shutdown and current limit protection prevent damage.
- Facteur de forme compact : Small size fits well in tight enclosures and projects.

Installation or Setup
- Identify input terminals (IN+ and IN-) and output terminals (OUT+ and OUT-).
- Solder power source wires to the input terminals with correct polarity.
- Connect output terminals to the load or multimeter for adjustment.
- For currents over 2A, attach an external aluminum heat sink to the LM2596 IC.
Comment utiliser
- Connect input terminals to a stable DC power source (4.5V to 40V).
- Assurer le volume d'entréetage is at least 1.5V higher than the desired output.
- Power on the input source.
- Mesurer le volume de sortietage with a digital multimeter at OUT+ and OUT-.
- Ajuster le volume de sortietage using the blue multi-turn potentiometer:
- Turn clockwise to increase voltage.
- Turn counterclockwise to decrease voltage.
- Turn off the power, disconnect the multimeter, and connect your device.
- Power on to operate your system.
Entretien et nettoyage
- Keep the module clean and dust-free to prevent overheating.
- Use a soft anti-static brush or compressed air for cleaning.
- Store in an anti-static bag when not in use.
- Avoid moisture exposure to prevent damage.
Conseils de sécurité
- Never reverse input polarity (no reverse polarity protection).
- Conserver le volume d'entréetage en dessous de 40 V CC.
- Avoid operating at 3A max current without proper cooling.
- Keep away from flammable materials during high-load use.
Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| Volume de sortietage equals input voltage | Potentiometer not engaged | Turn the potentiometer counterclockwise 15-20 turns |
| The module becomes excessively hot | High current or large voltage différentiel | Reduce load, add a heat sink or active cooling |
| Pas de voltage sortie | Wrong input connections or low input voltage | Verify wiring and input voltage au-dessus de 4.5V |
| Volume de sortietage fluctue | Unstable or insufficient input voltage | Stabiliser le volume d'entréetage, ensure ≥1.5V above output |
