5. Operating Modes

The SPS3010-2KD offers three primary output configurations, selectable via the front panel buttons: Independent, Series, and Parallel.

Diagram illustrating the three output modes: Independent (INDEP) providing two 30V 10A outputs, Series (SER) providing one 60V 10A output, and Parallel (PAR) providing one 30V 20A output. Each mode is shown with corresponding multimeter readings.
Figure 3: Overview of Independent, Series, and Parallel Output Modes.

5.1 Independent Output Mode (INDEP)

In this mode, the power supply functions as two separate 30V 10A DC power supplies. Each channel (CH1 and CH2) has independent voltage and current controls and output terminals.

Video 1: Demonstration of Dual Output Mode operation.
  1. Press the INDEP button. Both CH1 and CH2 displays will be active.
  2. Use the CH1 Current and Voltage knobs to set the desired output for Channel 1.
  3. Use the CH2 Current and Voltage knobs to set the desired output for Channel 2.
  4. Connect your load to the respective CH1 or CH2 output terminals.

5.2 Series Output Mode (SER)

This mode combines the two channels in series to provide a higher voltage output, up to 60V, with a maximum current of 10A. Only the left display (CH1) will be active, showing the combined output.

  • Storage: When not in use for extended periods, store the power supply in a cool, dry environment, away from direct sunlight and excessive dust.

8. Troubleshooting

If you encounter issues with your power supply, refer to the following common problems and solutions:

ProblemPossible CauseSolution
No power/display offPower cord not connected, power switch off, or power outage.Check power cord connection, ensure power switch is on, verify wall outlet functionality.
No output voltage/currentOutput terminals not connected, voltage/current set to zero, or protection activated.Ensure test leads are securely connected. Adjust voltage/current settings using encoder knobs. Check for activated protection indicators (e.g., OVP, OCP).
Inaccurate readingsLoose connections, uncalibrated external meter, or internal issue.Verify all connections are tight. Compare readings with a known calibrated multimeter. If discrepancies persist, contact support.
Unit overheatsBlocked ventilation, excessive load, or fan malfunction.Ensure clear airflow around the unit. Reduce load if operating near maximum capacity. Check if cooling fans are operating.
Difficulty adjusting valuesIncorrect use of encoder knob.Remember to press the encoder knob to select the digit you wish to adjust before rotating.

Note: This unit does not feature an output disable switch. Always ensure test leads are disconnected from your circuit before powering on or making significant adjustments to prevent accidental damage to connected devices.
