It also includes an auxiliary output terminal and is compatible with the SPS-H 19-inch rack mount adapter.
2. Important Safety Instructions
To prevent electric shock, fire, or damage to the unit, please observe the following safety precautions:
- Ensure the power supply is connected to a properly grounded AC outlet.
- Do not operate the unit in wet or damp conditions.
- Do not open the casing; there are no user-serviceable parts inside. Refer all servicing to qualified personnel.
- Ensure adequate ventilation around the unit. Do not block ventilation openings.
- Use only the specified input voltage range.
- Disconnect power before making any connections or disconnections to the output terminals.
- Do not exceed the maximum output voltage or current ratings.
- This device is intended for indoor use only.

- AC Power Input: For connecting the main power cord.
- Cooling Fan: Ensures proper heat dissipation during operation.
- Grounding Terminal: For safety grounding.
4. Setup
4.1 Initial Setup
- Unpacking: Carefully remove the power supply from its packaging and inspect for any damage.
- Placement: Place the unit on a stable, level surface with adequate space for ventilation (at least 10 cm clearance on all sides). Avoid direct sunlight, high temperatures, and dusty environments.
- Power Connection: Ensure the power supply's output is OFF. Connect the provided AC power cord to the AC power input on the rear panel and then to a grounded AC outlet.
- Grounding: For additional safety, connect a grounding wire from the grounding terminal on the rear panel to an appropriate earth ground.
- Load Connection: With the output OFF, connect your load to the output terminals (red for positive, black for negative). Ensure connections are secure.

5. Operating Instructions
5.1 Powering On/Off
Press the main power switch on the front panel to turn the unit ON. The LED display will illuminate. Press again to turn OFF.
5.2 Setting Voltage and Current
Voltage Adjustment: Rotate the encoder knob to adjust the voltage. A short press on the knob allows switching between coarse and fine adjustment modes. The active digit for adjustment will blink.
Current Adjustment: Press the encoder knob for 2 seconds to switch to current adjustment mode. Rotate the knob to set the desired current limit. Press again for 2 seconds to return to voltage adjustment mode.
5.3 Output On/Off Function
After setting the desired voltage and current, press the "Output On/Off" button to enable or disable the power output to the terminals. The display will indicate when output is active.
5.4 Over Voltage Protection (OVP)
The OVP feature protects the connected load from excessive voltage. If the output voltage exceeds the set OVP limit, the power supply will automatically shut down the output. To reset, turn the output OFF, adjust the OVP limit if necessary, and then turn the output ON again.
5.5 Over Current Protection (OCP)
The OCP feature protects the connected load and the power supply from excessive current. If the output current exceeds the set OCP limit, the power supply will automatically shut down the output. To reset, turn the output OFF, adjust the OCP limit if necessary, and then turn the output ON again.
5.6 Using the Auxiliary Output Terminal
The auxiliary output terminal provides a secondary output for specific low-power applications. Refer to the specifications for its exact voltage and current ratings.
5.7 Rack Mount Adapter (SPS-H 19inch)
The SPS-3030HP can be installed into a standard 19-inch equipment rack using the SPS-H rack mount adapter (sold separately). Follow the instructions provided with the adapter for proper installation. Ensure adequate airflow when rack-mounted.
6. Maintenance
6.1 Care and Maintenance
- Cleaning: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Ventilation: Regularly check that the ventilation openings are clear of dust and debris to ensure proper cooling.
- Storage: When not in use for extended periods, store the power supply in a dry, dust-free environment.
7. Troubleshooting Guide
If you encounter issues, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Display off | Power cord not connected; AC outlet faulty; Power switch off. | Check power cord connection; Test AC outlet; Ensure power switch is ON. |
