5. Configuració
- Col·locació: Place the power supply on a stable, level surface. Ensure there is sufficient space around the unit for proper ventilation. Do not block the ventilation grilles.
- Connexió d'alimentació: Connect the supplied power cord to the AC input socket on the rear of the power supply and then to a suitable mains outlet (100-240V AC, 50/60Hz).
- Connexió de càrrega: With the power supply turned OFF (power switch in '0' position), connect your load to the output terminals. Connect the positive (+) terminal of your load to the red (+) output terminal of the power supply, and the negative (-) terminal of your load to the black (-) output terminal. Ensure connections are secure.
6. Instruccions de funcionament
- Encès: After connecting your load, switch the power supply ON by pressing the power switch to the 'I' position. The unit will provide a fixed 24 V/DC output.
- Monitor Current: Observe the ammeter to monitor the current drawn by your connected load. Ensure the current does not exceed the maximum rated output of 3 A.
- Apagar: To disconnect the load or stop operation, switch the power supply OFF by pressing the power switch to the '0' position. Then, safely disconnect your load.
7. Manteniment
- Neteja: Disconnect the power supply from the mains before cleaning. Use a soft, dry cloth to clean the exterior. Do not use abrasive cleaners or solvents.
- Ventilació: Regularly check that the ventilation grilles are free from dust and obstructions to ensure proper airflow and prevent overheating.
