5. Instruccions de funcionament

5.1. Configuració Voltage i Actual

The SPS-3010C uses encoder knobs for precise digital adjustment of voltage i corrent.

Figure 5.1: Encoder Knob Adjustment for Voltage i Actual

• Voltage Ajust:
  • Premeu el botó Voltage Pom (gruixut) to select the digit before the decimal point. Rotate the knob to change the value.
  • Premeu el botó Voltage Pom (Fi) to select the digit after the decimal point. Rotate the knob to change the value.
  • The resolution for voltagLa configuració és de 0.01 V.
• Ajust actual:
  • Premeu el botó Control actual (gruixut) to select the digit before the decimal point. Rotate the knob to change the value.
  • Premeu el botó Control actual (Fi) to select the digit after the decimal point. Rotate the knob to change the value.
  • The resolution for current setting is 0.001A.

5.2. Control de sortida ON/OFF

Després d'ajustar el volum desitjattage and current, press the Botó de control de sortida to enable or disable the main DC output. The display will show the actual output values when enabled.

5.3. Intelligent Battery Charging Mode

This function allows for safe and efficient charging of various battery types.

Figure 5.2: Intelligent Battery Charging Function

1. Connect the battery to the output terminals, ensuring correct polarity (+ to + and - to -). The unit has built-in reverse connection protection.
2. Set the desired charging voltage and current limit using the encoder knobs.
3. Premeu el botó CHG Setting Button to activate the Intelligent Battery Charging function. The CHG indicator will illuminate.
4. The display will show real-time charging power (Ah). The power supply will automatically stop charging when the battery reaches the set voltage.

5.4. USB-A & USB-C Quick-Charge Ports

The unit includes dedicated USB-A and USB-C ports for quick charging external devices.

Figura 5.3: Funcionalitat de càrrega USB

• Both USB-A and USB-C ports support 20W fast charging.
• These ports provide fixed voltage and current output and are independent of the main DC output settings.
• Simply connect your compatible device to the appropriate USB port for charging.

5.5. OPN (Output Power ON) Function

The OPN function determines the state of the main DC output when the unit is powered on.

• When OPN is enabled, the main DC output will automatically turn ON with the previously set voltage and current parameters as soon as the power switch is engaged.
• When OPN is disabled, the main DC output will remain OFF upon power-up, requiring a manual press of the Botó de control de sortida per activar.
• Consult the full instruction manual for details on how to enable or disable the OPN function.

6. Característiques de protecció

• OCP (Over-Current Protection): This feature protects the connected load from excessive current. When activated, if the output current exceeds the set OCP threshold, the output will be shut off, and the OCP Status LED will illuminate.


Figure 6.1: Over-Current Protection in action

• Temperature-Regulated Cooling Fan: An internal fan automatically adjusts its speed based on the unit's temperature to prevent overheating during operation.
• Protecció de connexió inversa: For battery charging, this feature prevents damage to the power supply and battery if the polarity is accidentally reversed.

7. Manteniment

• Neteja: Disconnect the power supply from the mains before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
• Ventilació: Regularly check that the cooling fan vents are clear of dust and debris to ensure proper airflow.
• Emmagatzematge: Guardeu la unitat en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes quan no l'utilitzeu.

8. Solució De Problemes

• Sense energia:
  • Check if the power cord is securely connected to both the unit and the electrical outlet.
  • Assegureu-vos que l'interruptor d'alimentació estigui en la posició ON.
  • Verify the AC Input Selectable Switch on the rear panel is set correctly (115V/230V).
  • Check the fuse in the Fuse Box on the rear panel. Replace if blown with a fuse of the same rating.
• Sense Vol de sortidatage/Actual:
  • Assegureu-vos el Botó de control de sortida is pressed and the output is enabled.
  • Check if OCP is active (OCP Status LED illuminated). If so, clear the fault condition and reset OCP.
  • Comproveu que el voltagLa configuració e i actual no estan establertes a zero.
• Inaccurate Current Display at Low Loads: At very low current settings (e.g., below 15mA), the displayed current may show a slight deviation (e.g., 2mA less than actual). This is a characteristic of some switching power supplies and typically does not affect performance for most applications.
• Voltage Transients During Load Changes: When connecting loads with large capacitance, especially if the power supply is already enabled at a high voltage, a brief current surge may occur as the output capacitance discharges into the load. It is recommended to connect the load with the output disabled, then enable the output.
