- AC Power Input: For connecting the supplied AC power cord.
- Cooling Fan: Automatically activates when the internal temperature exceeds 50°C (122°F) to maintain optimal operating temperature.
- Fuse Box: Contains the protective fuse.
- Voltage Selector Switch: Allows selection between 115V and 230V AC input. Ensure this is set correctly for your region.
4. Setup
- Unpacking: Carefully remove the power supply and all accessories from the packaging.
- Placement: Place the unit on a stable, level surface with adequate ventilation around all sides. Avoid placing it near heat sources or in direct sunlight.
- Input Voltage Selection: Before connecting the AC power cord, verify that the voltage selector switch on the rear panel is set to the correct voltage for your local power grid (115V or 230V).
- Power Connection: Connect the supplied AC power cord to the AC power input on the rear panel and then to a grounded wall outlet.
- Output Connections: Ensure the power supply is OFF (Power Switch) and the OUTPUT is disabled before connecting any load. Connect the red output test line to the positive (+) terminal and the black output test line to the negative (-) terminal. Connect the other end of the test lines to your device or circuit.
5. Operating Instructions
5.1 Basic Voltage and Current Adjustment

Image: Demonstrates the operation of the high-precision encoder adjustment knobs for setting voltage and current.
- Turn on the power supply using the Power Switch.
- Adjusting Voltage: Rotate the Voltage Adjustment Knob to set the desired voltage. Press the knob to select a specific digit on the voltage display, then rotate to fine-tune that digit.
- Adjusting Current: Rotate the Current Regulation Knob to set the desired current limit. Press the knob to select a specific digit on the current display, then rotate to fine-tune that digit.
- Once voltage and current are set, press the OUT button to enable the output. The OUT indicator will illuminate green.
- To disable output, press the OUT button again.
5.2 Memory Presets (M1, M2, M3)
The power supply allows you to save and recall three frequently used voltage and current settings.

- Saving Settings: Set the desired voltage and current using their respective knobs. Long press one of the M1, M2, or M3 buttons for approximately 3 seconds until a beep confirms the settings are saved.
- Recalling Settings: Short press the desired M1, M2, or M3 button to instantly recall the saved voltage and current values.
5.3 Output Enable/Disable
The OUT button controls the activation of the DC output terminals.
- Pressing OUT enables the output, and the indicator light turns green.
- Pressing OUT again disables the output, and the indicator light turns off. This feature prevents accidental short circuits or damage during connection changes.
5.4 Over Current Protection (OCP)
The OCP function protects your connected device and the power supply from excessive current draw.

Image: Visual representation of the multiple protection functions, including OCP, output enable, and locking key.
- Press the OCP switch to activate Over Current Protection. The OCP indicator will illuminate.
- If the output current exceeds the set limit while OCP is active, the power supply will automatically stop output and display "OCP".
- To resume operation after an OCP event, clear the short circuit or overload condition, then press the OUT button to re-enable output.
5.5 Locking Function
The locking function prevents accidental changes to the set voltage and current values.
- Press the Function Lock Button (lock icon) to lock the control panel. The lock indicator will illuminate red.
- While locked, the voltage and current knobs, and memory buttons will not respond to input.
- Press the Function Lock Button again to unlock the panel.

6. 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 cooling fan and vents are free from dust and obstructions. Blocked vents can lead to overheating.
- Fuse Replacement: If the unit fails to power on, the fuse may need replacement. Disconnect the AC power cord, locate the fuse box on the rear panel, and replace the fuse with one of the same type and rating (e.g., T3.15AL 250V for 230V input, T6.3AL 250V for 115V input).
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power when turned on | AC power cord not connected; Power switch off; Blown fuse; Incorrect input voltage selection. | Check AC power cord connection; Ensure Power switch is ON; Replace fuse (see Maintenance); Verify input voltage selector switch setting. |
| No output voltage/current | Output disabled (OUT button); OCP activated; Short circuit in load. | Press OUT button to enable output; Check OCP status and clear fault; Inspect load for short circuits. |
| Voltage/Current cannot be adjusted | Function Lock is active. | Press the Function Lock Button to unlock the panel. |
| Unit overheats | Blocked ventilation; Prolonged high load operation. | Ensure vents are clear; Reduce load or operate in a cooler environment. |
