2. Safety Instructions
- Ensure the input AC voltage is within the specified range of 100V~240V, 50~60Hz.
- Do not operate the power supply in wet or damp conditions.
- Avoid blocking the ventilation openings. The cooling fan starts automatically to prevent overheating.
- If the power supply becomes excessively hot, discontinue use immediately and allow it to cool down to prevent irreversible damage.
- Always connect the load before turning on the power supply.
- Do not exceed the maximum output power of 150W. The device will prevent setting values that exceed this limit.
- Ensure proper grounding.
- Keep out of reach of children.
3. Product Overview
The NICE-POWER SPS-E3010 is a compact and portable DC power supply designed for various applications. Key features include:
- Variable Output: Adjustable voltage from 0-30V and current from 0-10A.
- Power Limit: Maximum output power is 150W. Note that when current is set to 10A, voltage cannot exceed 15V. When voltage is set to 30V, current cannot exceed 5A.
- 3-Digit LED Display: Provides clear readings for voltage (accurate to 0.1V) and current (accurate to 0.01A).
- Encoder Buttons: High-precision encoder knobs for accurate digital adjustment of voltage and current.
- Automatic Cooling Fan: Activates automatically to maintain optimal operating temperature and extend service life.
- Wide AC Input: Supports 100V~240V AC input, suitable for global use.

4. Setup
- Unpacking: Carefully remove the power supply and all accessories from the packaging. Verify that all components listed in the packing list are present: 1x DC power supply, 1x Output Power Cords, 1x Input Power Cord, 1x User Manual.
- Placement: Place the power supply on a stable, flat surface with adequate ventilation. Ensure that the air vents on the sides and rear are not obstructed.
- Power Connection: Connect the provided input power cord to the AC inlet on the rear of the power supply and then to a suitable AC power outlet (100V~240V).
- Output Connection: Connect the red output power cord to the red (+) terminal and the black output power cord to the black (-) terminal on the front panel. Connect the other ends of the output cords to your load device.
- Initial Power On: Press the power button on the front panel. The LED display will illuminate, and the cooling fan may start briefly.

5. Operating Instructions
5.1 Adjusting Voltage and Current
The SPS-E3010 uses encoder knobs for precise adjustment of output voltage and current. This allows for setting exact values rather than just adjusting them.
- Select Digit: Press the Voltage knob or Current knob to select the specific digit you wish to adjust on the LED display. The selected digit will typically blink or be highlighted.
- Adjust Value: Rotate the selected knob (Voltage or Current) to set the desired value for that digit (from 0 to 9).
- Repeat steps 1 and 2 for each digit until the desired voltage and current values are displayed.
- Power Output Limit: Remember the 150W power limit. For example, if you set the current to 10A, the maximum adjustable voltage will be 15V. If you set the voltage to 30V, the maximum adjustable current will be 5A. The device will prevent settings that exceed 150W.

5.2 Constant Voltage (C.V) and Constant Current (C.C) Modes
The power supply operates in two primary modes:
- Constant Voltage (C.V): When the load current is below the set current limit, the power supply maintains a constant output voltage. The C.V indicator will be lit.
- Constant Current (C.C): When the load current reaches the set current limit, the power supply automatically switches to constant current mode, maintaining the set current by reducing the output voltage. The C.C indicator will be lit.
6. Application Scenarios
The NICE-POWER SPS-E3010 DC Power Supply is suitable for a variety of applications, including:
- LifePO4 battery charging and testing.
- Electroplating processes.
- Photovoltaic system testing.
- DIY electronics projects.
- Benchtop power for various electronic devices.

7. Maintenance
- Cleaning: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or aerosols.
- 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 cool, dry place away from direct sunlight and extreme temperatures.
- Overheating: As noted in safety instructions, if the unit becomes too hot, stop use and allow it to cool. Persistent overheating may indicate an issue requiring professional inspection.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Display off | Power cord not connected; Power switch off; Blown fuse. | Check power cord connection; Turn on power switch; Replace fuse (refer to specifications for fuse type). |
| No output voltage/current | Output terminals not connected; Voltage/current set to zero; Overload protection activated. | Ensure output cables are securely connected; Adjust voltage/current knobs to desired values; Reduce load or check for short circuit. |
