5. Operating Instructions
This section details how to operate your power supply.
5.1 Front Panel Overview
Image: Front panel of the JT-DPS5015, highlighting the digital display for voltage, current, and power, along with the control buttons and rotary encoder for parameter adjustment. This visual aid helps users locate and understand the function of each control element.
- Display: Shows real-time output voltage, current, and power.
- Voltage/Current Knobs: Used to adjust the desired output voltage and current limits.
- Output ON/OFF Button: Toggles the power output to the load.
- Set Button: Enters parameter setting mode.
5.2 Basic Operation
- Power On: Turn on the main power switch. The display will illuminate.
- Set Voltage: Use the voltage adjustment knob to set the desired output voltage. Observe the display for the set value.
- Set Current Limit: Use the current adjustment knob to set the maximum allowable output current. This acts as a current limit for your load.
- Enable Output: Press the 'Output ON/OFF' button to enable the power output to your connected load. The output indicator will light up.
- Disable Output: To safely disconnect or adjust the load, press the 'Output ON/OFF' button again to disable the output.
5.3 Protection Features
- Over Voltage Protection (OVP): If the output voltage exceeds a preset limit, the power supply will automatically shut down the output to protect the connected load.
- Over Current Protection (OCP): If the output current exceeds the set current limit, the power supply will enter constant current mode or shut down the output, depending on the setting, to protect the load and the power supply itself.
6. Maintenance
Proper maintenance ensures the longevity and reliable operation of your power supply.
- Cleaning: Disconnect the power supply from the main power source 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 free from dust and debris. Use compressed air to clear any blockages 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.
7. Troubleshooting
