4. Setup
- Unpacking: Carefully remove the power supply from its packaging. Inspect for any signs of damage.
- Placement: Place the unit on a stable, level surface with adequate ventilation around all sides. Do not block the cooling fan vents.
- Power Connection: Connect the provided power cord to the AC input on the rear panel and then to a grounded wall outlet.
- Initial Power On: Flip the main power switch on the front panel to the 'ON' position. The LED display should illuminate.
- Output Connection: Connect your load to the main output terminals using appropriate test leads. Ensure correct polarity (red to positive, black to negative). For auxiliary output, use the dedicated terminal.
5. Operating Instructions
5.1 Adjusting Voltage and Current
Image Description: This image illustrates the interaction with the digital display for setting voltage and current. It shows how to press a button to select the digit to adjust and then rotate the encoder knob to change the value, allowing for precise control over the output parameters.
- Power On: Turn on the power supply. Ensure the output is initially OFF.
- Set Voltage: Rotate the Voltage Adjustment Knob to set the desired output voltage. Pressing the knob allows you to select individual digits for fine-tuning.
- Set Current Limit: Rotate the Current Adjustment Knob to set the desired current limit. This acts as a maximum current the supply will deliver. Pressing the knob allows for digit selection.
- Enable Output: Once voltage and current limits are set, press the Output ON/OFF Switch to enable the power output. The display will show the actual output voltage and current.
- Disable Output: To stop the output, press the Output ON/OFF Switch again.
5.2 Over-Voltage Protection (OVP) and Over-Current Protection (OCP)
Image Description: This image highlights the Over-Current Protection (OCP) alarm feature. It shows the power supply's display and indicates that the OCP button can be used to detect and respond to short-circuits or over-current conditions, triggering an alarm and stopping the output to protect the connected device.
The power supply is equipped with OVP and OCP functions to protect both the device and the connected load from damage due to excessive voltage or current. If an OVP or OCP event occurs, the power supply will automatically cut off the output and trigger an alarm. To reset, address the cause of the over-condition, then cycle the output switch off and on.
5.3 Battery Charging Function
Image Description: This image demonstrates the battery charging function of the Jesverty SPS-10010H power supply. It shows the power supply connected to a lead-acid battery, with icons indicating compatibility with Ni-MH, Lithium, LiFePO4, and Lead-Acid batteries. A crucial note advises setting the current and voltage correctly before charging.
The SPS-10010H can be used for charging various battery types, including Ni-MH, Lithium, LiFePO4, and Lead-Acid batteries. Important: Always set the correct charging voltage and current limit according to the battery manufacturer's specifications before connecting the battery and enabling the output. Incorrect settings can damage the battery or the power supply.
6. Maintenance
- Cleaning: 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.
- Ventilation: Periodically check that the ventilation openings are free from dust and debris. Use compressed air to clear if necessary.
- Storage: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.
- Fuse Replacement: If the unit fails to power on, check the fuse located in the AC input socket on the rear panel. Replace with a fuse of the same type and rating (e.g., 10A).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power when switched on | Power cord not connected, wall outlet faulty, fuse blown. | Check power cord connection, test wall outlet, replace fuse if necessary. |
| No output voltage/current | Output switch is OFF, OVP/OCP triggered, faulty connection to load. | Turn output switch ON, check for OVP/OCP condition and reset, verify load connections. |
| Output voltage/current unstable | Loose connections, faulty load, internal issue. | Check all connections, test with a different load, contact support if problem persists. |
| Unit overheats | Blocked ventilation, excessive load. | Ensure vents are clear, reduce load or operating time. |
