2. Safety Instructions
Your safety is paramount. This power supply is designed with multiple protection functions, but proper handling is crucial to prevent damage or injury.
- Input Voltage: This DC power supply is designed for 110V input, meeting US standard voltage. 220V input is NOT supported for this model.
- Protection Features: The device includes leakage, grounding terminal, over-voltage, over-current, over-power, over-load, over-temperature, and short-circuit protection. These features ensure stable performance and prolong product life.
- Proper Use: Always use the power supply under occupied conditions. Avoid violent impact or dropping the device.
- Connection: Ensure all connections, especially positive (+) and negative (-) terminals, are correct before activating the output. Incorrect connections can damage the load.
- Accuracy Measurement: To correctly measure accuracy, do not connect any load and ensure the multimeter is properly set to the DC voltage/current measurement range.

5. Setup
- Unpacking: Carefully remove the power supply and all accessories from the packaging. Inspect for any signs of damage.
- Placement: Place the power supply on a stable, flat surface with adequate ventilation. Ensure the cooling fan at the rear is not obstructed.
- Connect Input Power: Plug the input power cord into the power supply's rear input socket, then into a standard 110V AC outlet.
- Connect Output Leads: Connect the provided output power cords to the corresponding terminals on the front panel: red to positive (+), black to negative (-), and green to ground (GND) if required by your application.
6. Operating Instructions
- Power On: Press the 'POWER' button on the front panel to turn on the device. The LED display will illuminate.
- Set Voltage and Current: Use the 'V-COARSE' and 'V-FINE' knobs to set the desired output voltage. Use the 'A-COARSE' and 'A-FINE' knobs to set the desired output current limit. The display will show the set values.
- Activate Output: Press the 'OUTPUT' button to enable the power output. The green indicator light next to the button will illuminate. The display will show the actual output voltage, current, and calculated power.
- C.V. / C.C. Mode: The power supply automatically operates in either Constant Voltage (C.V.) or Constant Current (C.C.) mode. The corresponding indicator (red LED) will light up to show the active mode.
- USB Port: The 5V/2A USB port is always active when the power supply is on, allowing you to charge compatible USB devices.
- Power Off: Press the 'OUTPUT' button to disable the output first, then press the 'POWER' button to turn off the device.

8. Troubleshooting
If you encounter issues with your power supply, please refer to the following common problems and solutions:
- No Output: Check if the 'OUTPUT' button is pressed (green indicator should be on). Verify input power connection.
- Incorrect Readings: Ensure all connections are secure. If using a multimeter for verification, ensure it's correctly set for DC voltage/current measurement and no load is connected to the power supply during calibration checks.
- Fan Not Running: The intelligent cooling fan only activates when the internal temperature exceeds 122°F/50°C. This is normal operation.
- Short Circuit Protection Activated: If a short circuit occurs, the power supply will automatically cut output and switch to C.C. mode (red LED). Disconnect the short, then re-enable output.
