5. Configuració

1. Desembalatge i inspecció: Carefully remove the power supply from its packaging. Inspect the unit for any signs of physical damage. Report any damage to your supplier immediately.
2. Connexió d'alimentació: Connect the supplied AC power cord to the power input on the rear panel of the SPD3303X-E and then to a grounded AC power outlet. Ensure the voltage selector (if present) is set correctly for your region.
3. Encesa inicial: Press the power switch located on the front panel. The display should illuminate, and the unit will perform a self-test.
4. Ventilació: Ensure adequate space around the unit for proper airflow to prevent overheating. Do not block the ventilation openings.

6. Funcionament

6.1 Configuració Voltage i Actual

To set the desired voltage and current for a channel:

1. Select the desired channel (CH1, CH2, or CH3) using the corresponding button.
2. Use the rotary encoder to adjust the voltage value. Press the encoder to switch between digits for fine adjustment.
3. Press the current setting button (usually labeled 'A' or 'I') and use the rotary encoder to set the current limit.
4. Press the output ON/OFF button for the selected channel to enable or disable the output.

6.2 Modes de sortida

The SPD3303X-E supports three primary output modes for Channels 1 and 2:

• Mode independent: Channels 1 and 2 operate as two separate power supplies, each with its own voltage i la configuració actual.
• Mode de sèrie: Channels 1 and 2 are connected in series to provide a higher output voltage (up to 64V). The current limit is determined by the lower of the two channel's current settings.
• Mode paral·lel: Channels 1 and 2 are connected in parallel to provide a higher output current (up to 6.4A). The voltage is determined by the master channel, and the total current limit is the sum of both channels' current settings.

Use the dedicated mode buttons on the front panel to switch between these configurations.

6.3 Timing Output Function

The timing output function allows you to program a sequence of voltage and current changes over time, useful for automated testing and characterization.

Figure 6.1: Display showing the Panel Timing Output settings, allowing users to program voltage and current sequences.

To use the timing output function, navigate to the timing menu on the display and configure the desired steps, including voltage, current, and duration for each step. Once programmed, activate the timing output to execute the sequence.

7. Manteniment

• Neteja: Feu servir un drap suau i sec per netejar l'exterior de la font d'alimentació. No utilitzeu productes de neteja abrasius ni dissolvents.
• Ventilació: Regularly check that the ventilation openings are clear of dust and debris. Blocked vents can lead to overheating and damage.
• Emmagatzematge: Quan no la feu servir durant períodes prolongats, guardeu la font d'alimentació en un entorn sec i sense pols.
• Calibració: Periodic calibration by qualified personnel is recommended to maintain measurement accuracy.

8. Solució De Problemes

If you encounter issues with your SPD3303X-E, refer to the following common troubleshooting steps:

• Sense energia:
  • Check the power cord connection to both the unit and the AC outlet.
  • Verify that the AC outlet is functional.
  • Check the fuse on the rear panel (if accessible and user-replaceable).
• Sense Vol de sortidatage/Actual:
  • Ensure the output for the selected channel is turned ON.
  • Consulteu el voltage and current limit settings; they might be set too low.
  • Verify connections to the load.
  • If in Constant Current (CC) mode, the voltage will drop to maintain the set current. If in Constant Voltage (CV) mode, the current will drop if the load resistance is too high.
• Indicació de sobrecàrrega:
  • Reduce the load or increase the current limit setting.
  • Check for short circuits in the connected load.

If the problem persists after attempting these steps, contact Siglent customer support or a qualified service technician.
