5. Configuració

1. Col·locació: Place the power supply on a stable, level surface with adequate ventilation. Ensure no obstructions block the cooling fan vents.
2. Connexió d'alimentació: Connect the provided AC power cord to the AC input socket on the rear panel of the power supply and then to a suitable wall outlet.
3. Encesa inicial: Flip the main power switch on the rear panel to the 'ON' position. The LED display on the front panel will illuminate.
4. Terminals de sortida: Connect your load to the positive (+) and negative (-) output terminals using appropriate test leads. For safety, ensure the output is OFF before connecting the load.

6. Instruccions de funcionament

6.1. Configuració Voltage i Actual

The SPS-1560N utilizes encoder knobs for precise adjustment of output voltage i corrent.

• Voltage Ajust: Gireu el 'Volum'tage' knob to adjust the desired output voltage. Press the knob to switch between coarse (whole number) and fine (decimal) adjustment modes. The resolution is 0.01V.
• Ajust actual: Rotate the 'Current' knob to set the maximum output current limit. Press the knob to switch between coarse and fine adjustment modes. The resolution is 0.001A.
• Sortida ON/OFF: Després d'ajustar el volum desitjattage and current, press the 'Output' button to enable or disable the power output to the load.

6.2. Mode CV i CC automàtics

The power supply automatically switches between Constant Voltage (C.V.) and Constant Current (C.C.) modes based on the load. The set voltage and current values act as the crossover point for mode switching.

• Vol. ConstanttagMode e (CV): When the load resistance is high, the output voltage remains constant at the set value, and the output current adjusts according to the load.
• Mode de corrent constant (CC): When the load resistance is low, the output current remains constant at the set limit, and the output voltage adjusts according to the load.

6.3. USB Output Terminals

The front panel includes USB-A and USB-C output terminals for convenient charging of compatible devices.

6.4. Funció de càrrega de la bateria

The power supply can be used for charging various battery types. Ensure correct voltage and current settings for the specific battery chemistry.

Figure 3: Battery Charging Application

• Important: Estableix sempre el corrent i el volumtage correctly according to the battery's specifications before initiating charging to prevent damage to the battery or the power supply.

7. Manteniment

• Mantingueu la unitat neta i lliure de pols. Feu servir un drap suau i sec per netejar-la.
• Ensure the ventilation openings are not blocked to allow proper airflow for the cooling fan.
• Store the power supply in a cool, dry environment when not in use.

8. Solució De Problemes

• Sense energia: Check the AC power cord connection, the main power switch on the rear, and the fuse.
• Sense sortida: Ensure the 'Output' button on the front panel is pressed to enable output. Check all connections to the load.
• Lectures incorrectes: Verify that the test leads are properly connected and that the multimeter (if used for verification) is calibrated and set correctly.
• Protecció de sobrecàrrega: If the OCP (Over Current Protection) or OVP (Over Voltage Protection) indicator lights up, disconnect the load, reduce the set current/voltage, and then re-enable the output.
