• AC Selector Switch (110V/220V): Selects the appropriate input voltage.
• Cooling Fan: Provides air circulation for heat dissipation.

4. Setup

Follow these steps to set up your power supply:

1. Unpacking: Carefully remove the power supply from its packaging. Inspect for any signs of damage.
2. Placement: Place the unit on a stable, level surface with adequate ventilation around the rear cooling fan.
3. Input Voltage Selection: Locate the AC selector switch on the rear panel. Ensure it is set to match your local mains voltage (110V or 220V). Incorrect setting can damage the unit.

5. Operating Instructions

5.1 Basic Operation

1. Power On: Flip the Instrument Power Switch on the front panel to the 'ON' position. The display will illuminate.
2. Set Voltage: Rotate the Voltage Regulation Knob to adjust the desired output voltage. Push the knob for fine adjustment, release for coarse adjustment.
3. Set Current Limit: Rotate the Current Regulation Knob to set the maximum output current limit. Push the knob for fine adjustment, release for coarse adjustment. This acts as a current protection threshold.
4. Enable Output: Press the Output Switch Menu Function Key to enable the power output. The 'OUTPUT' indicator will light up. The voltage and current displays will show the actual output values.

7. Power Off: Press the Output Switch Menu Function Key to disable the output, then flip the Instrument Power Switch to 'OFF'.

5.2 Memory Function

The power supply allows you to save and recall two sets of voltage and current settings (M1, M2).

1. Saving Settings:
   • Adjust the Voltage Regulation Knob and Current Regulation Knob to your desired values.
   • Press and hold either the M1 or M2 button until a confirmation beep or indicator appears, indicating the settings are saved.
2. Recalling Settings:
   • Briefly press the M1 or M2 button. The saved voltage and current values will be loaded and displayed.

5.3 OVP/OCP Settings (Over Voltage/Current Protection)

The unit features adjustable Over Voltage Protection (OVP) and Over Current Protection (OCP) to safeguard connected devices and the power supply itself.

1. Setting OVP:
   • With the output disabled, long-press the Voltage Regulation Knob. The display will show the current OVP setting.
   • Rotate the knob to adjust the OVP threshold. This value should be set slightly above your desired maximum operating voltage.
   • Briefly press the knob again to confirm and exit OVP setting mode.
2. Setting OCP:
   • With the output disabled, long-press the Current Regulation Knob. The display will show the current OCP setting.
   • Rotate the knob to adjust the OCP threshold. This value should be set slightly above your desired maximum operating current.
   • Briefly press the knob again to confirm and exit OCP setting mode.

6. Maintenance

Proper maintenance ensures the longevity and reliable operation of your power supply.

• 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: Ensure the ventilation holes and cooling fan on the rear panel are free from dust and obstructions. Periodically clean with compressed air if necessary.
• Storage: When not in use for extended periods, store the power supply in a dry, dust-free environment.
