5. Impostazione

1. Disimballaggio: Carefully remove the power supply from its packaging. Inspect the unit for any signs of damage during transit. Retain the packaging for future storage or transport.
2. Posizionamento: Place the power supply on a stable, level surface. Ensure there is sufficient space around the unit for proper ventilation, especially around the rear fan and side vents. Avoid placing it near heat sources or in direct sunlight.
3. Collegamento elettrico: Connect the provided 220V AC power cord to the power input socket on the rear of the unit, then plug the other end into a grounded 220V AC wall outlet.
4. Accensione iniziale: Press the Power On/Off button on the front panel. The digital displays should illuminate.
5. Collegamento del cavo di uscita: Before connecting any load, ensure the power supply output is disabled (OUTPUT button LED off). Connect your load using appropriate test leads to the Positive (+) and Negative (-) output terminals. For safety, connect the ground (GND) terminal to the chassis of your circuit if required.

6. Istruzioni per l'uso

6.1 Impostazione del volumetagee Limiti di corrente

1. Imposta Vol.tage: With the output disabled (OUTPUT button LED off), use the COARSE V E FINE V knobs to set the desired output voltage. Osservare il Voltage Visualizza.
2. Imposta limite corrente: With the output disabled, use the COARSE A E FINE A knobs to set the desired maximum current limit. This acts as a safety feature to protect your circuit.
3. Abilita output: Una volta voltage i limiti di corrente sono impostati, premere il tasto PRODUZIONE button. The LED will illuminate, and power will be supplied to the output terminals.

6.2 Volume costantetagModalità e (CV) e corrente costante (CC)

• Volume costantetage (CV) Modalità: When the load current is below the set current limit, the power supply operates in CV mode. The output voltage remains constant at the set value, and the CV l'indicatore LED si accenderà.
• Modalità corrente costante (CC): If the load current attempts to exceed the set current limit, the power supply automatically switches to CC mode. The output current is maintained at the set limit, and the output voltage will drop to protect the load. The CC l'indicatore LED si accenderà.

6.3 Using the 5V/2A USB Output

The front panel includes a dedicated 5V/2A USB port. This port provides a fixed 5V output with a maximum current of 2A, independent of the main adjustable output. It can be used to power or charge compatible USB devices.

7. Manutenzione

• Pulizia: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use abrasive cleaners or solvents.
• Ventilazione: Periodically check the ventilation openings for dust accumulation. Use compressed air to gently clear any blockages to ensure proper airflow.
• Magazzinaggio: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to use the original packaging for storage.
• Ispezione dei cavi: Regularly inspect the power cord and output cables for any signs of damage, fraying, or loose connections. Replace damaged cables immediately.
